Ethernet upgrade for the Master series: The philosophy of the BBC Microcomputer series included the ability to network several computers together to allow expensive peripherals such as printers to be shared between several users - often in a classroom or small business environment. This 'Econet' network was offered as an option on most machines, and in the case of the BBC Master series as a user installable plug in module. Despite its robustness the majority of other computer vendors eventually adopted the Ethernet standard instead using variable length messages called Internet Protocol ('IP') packets. The Master 10/100 net module allows the BBC Master series to be retrospectively upgraded to communicate with an Ethernet network, sharing peripherals and information with other personal computers.

sd2iec file dump: Welcome to the official dumping ground for sd2iec firmware releases. The most up-to-date source code and binary files for sd2iec are linked below. Normal users will only need the file, developers may be interested in the source tarball. This is currently the only up-to-date release version of sd2iec, if you find any version named 0.something on this or any other web site, it is obsolete and only archived for historical preservation.

SSSSAM: Text-to-speech for the Commodore computer. If you owned a C64, an Atari or an Apple computer, then you might be familiar with the synthetic sound of the voice of SAM. The Software based text-to-speech speech synthesizer package that required no additional hardware. But if back then, you only had a VIC-20 then you missed out, because SAM won't run on such a system, there simply aren't enough resources, since the VIC-20 doesn't have enough RAM. But the project on this page is about SAM and this project does work perfectly fine on a VIC-20 (and also on various other Commodore computers that have a userport).

The Commodore Knowledge Base: The Commodore Knowledge Base is an assimilation of various articles on Commodore repair, programming and technical issues, ranging from beginner level to advanced, covering a diverse series of topics from CP/M to hardware modifications. CKB covers the gamut of Commodore 8-bit systems, not Amiga and very little on the PC series. Emulator content is intentionally limited, although cross-platform development is a considered topic. CKB articles originate from many sources, largely the Usenet group comp.sys.cbm, patrolled by a news robot maintained by Cameron Kaiser. Kurt Brandon has also provided a significant number of articles gleaned from BBSes and the now defunct QLink online service. Other notable contributors include: Marko Mäkelä, Stephen Judd, John Iannetta, Doug Cotton, Nicolas Welte, Jim Butterfield, Jim Brain, Ray Carlsen.

The Future was 8bit - SD2IEC: Of all the methods of loading stuff into your Commodore, TFW8b's SD2IEC SD card interfaces are the business. SD2IEC provides much of the functionally a 1541 disk drive, supports fast loaders like JiffyDos, Final Cartridge III and Epyx FastLoad. version of the SD2IEC is the most common method of loading/saving on a Commodore 8bit Today!

The Secret Weapons of Commodore!: They were the secret weapons! The unrealized phantasms of technological wonder! The ravings of mad geniuses made flesh and locked away in caverns of dust never to see the light of day! The demons that Tramiel forgot, to come tapping at their door even as the winds of oblivion beckon and spit!

Uno2iec: A commodore (CBM) 1541 emulator on the Arduino Uno, using any desktop PC (or raspberry PI with raspbian) as a media host.

The host system location can be a network share, an USB or SD flash media, SSD or any hard disk that is supported by a Windows, Linux or Mac operating systems.


ADF-Copy: ADF-Copy is a small hardware i developed which uses a Teensy 3.2 microcontroller to read and write non copy protected Amiga disks with an out of the box PC 3.5″ Floppy drive connected to the microcontroller which can be build with a few jumper wires on a breadboard with no additional component. The low level stuff is handled in the microcontroller which is controlled by a Java application.

A.D.A. Amiga Demoscene Archive: On the Amiga Demoscene Archive, you will find some of the best demos and intros released on the Amiga.

A314: The A314 is an expansion board for the Amiga 500 that goes in the trapdoor expansion slot. A Raspberry Pi (RPi) is attached to the A314, and the A500 and the RPi can communicate through a shared memory. We have constructed a communication protocol through which associated processes on each platform (Amiga and RPi) can allocate logical channels, carried over one physical SPI channel. The protocol is handled by a driver on each side (a314.device on the Amiga and a314d on the RPi). The drivers are responsible for alerting receiving processes of incoming data via an interrupt.

AMIGA 500 - SWITCHLESS BOOT SELECTOR (3 RESET BOOT DRIVE SELECTOR): “A500 - Switchless Booter” is a circuit for changing boot priority of floppy drives, for Amiga 500. If you use a second floppy drive connected to your A500, like GOTEK Drive or a mechanical floppy drive, (as DF:1), then you need a boot selector to boot from the second drive. (Most of old boot selectors work with a toggle switch.)

Amiga-Digital-Video: Add pixel-perfect HDMI output to the Amiga machines. For all Amiga versions that have a socketed DIP Denise chip, a rather small adapter board can be used to extract the digital video signal (12 bit) to a 40-pin connector compatible with the Raspberry Pi Zero. This can then be used with the RGBtoHDMI software to produce a perfect HDMI picture with very low latency (a few milliseconds at most).

DiagROM: DiagROM is a diagnostic tool for the amiga computers. And it is to be used on defective machines, trying to help no-boot situations etc. You simply replace the Kickstart roms in the Amiga with the DiagROM. and when poweron. your Amiga will start a diagnostic software. It will try to dump info on the serialport (and actual menus etc aswell) while also trying on the screen. One important thing is that the software relies on as little hardware as possible. so no timers, no IRQ etc. so you can start up the machine on a very broke machine and from that test different things. and hopefully help finding hardwareissues.

phase5 - Drivers/Libraries

PiStorm: The PiStorm itself is an adapter board intended to be paired with a Raspberry Pi Model 3A+. It goes in the DIP socket on and acts in place of the CPU, but functionality can be extended beyond simple CPU emulation. While the PiStorm should work with any DIP socket 16-bit 68000-powered system, the FC lines are currently not properly handled and no guarantees can be made for it working on anything except an Amiga 500, 500+ and 2000. General Performance with the current use of Musashi as the 68k CPU emulator is somewhere around a 70-80 MHz 68030.

The Amiga 1000 Parceiro: The Parceiro (sounds like par-say-ro) attaches to the side expansion port of the Amiga and is about the size of a harmonica that’s been run over by a steam roller as it’s only about 1/3 of an inch thick. It provides the following features: 8MB of Autoconfig Fast RAM. It is a single 8MB of SRAM versus DRAM, so it really and truly is indeed fast with zero wait states - Coin-cell battery backed Real Time Clock (RTC), which comes with its own clock software that gets put into your startup sequence - SD Card Reader with 2GB MicroSD. It comes pre-formatted with the FAT32 file system and is readable on any PC as a result. This way you can quickly set up your new SD-based hard drive. It’s worth mentioning that this is running on period correct Amiga OS 1.3, too.

X-Surf-100: X-Surf-100 is a Z2/Z3 auto-sensing card: In an Amiga 2000, it will work as a Zorro-2 card. In an A3000 or A4000 computer, it will work as a Zorro-3 card. For stable operation, a Buster-11 chip is recommended. Proper function is only guaranteed in original Commodore daughterboards. The X-Surf-100 may or may not work in second-source daughter boards like Elbox, RBM or Eagle. Should you experience instabilities, you can close the jumper on your X-Surf-100, which will force the slower Z2 mode, even in Z3 computers. This may or may not give you stable operation in daughter boards that are not fully Zorro-compliant.

X-Surf-500: X-Surf-500 is the networking card for both the ACA500 and the ACA500plus accelerators. While it offers full 100MBit networking support and comes with a TCP/IP stack included, it comes at a very competitive price.

ZoomFloppy: ZoomFloppy brings Commodore disk archival into the 21st Century, bridging the gap between the both the IEEE-488 and IEC-based disk intelligent Commodore™ disk drive line and contemporary personal computers. Taking up the baton from the ever-popular X*-1541 line of parallel port interfaces, ZoomFloppy provides complete functionality for newer machines running multitasking and multi-user operating systems and those systems lacking the legacy parallel port upon which the X*-1541 interfaces depend.


Commodore 128 40/80 Column Video Adapter: I was looking for a solution to be able to display 80 column video of my C128 onto my TV in color. Various schematics were out there, but all had different drawbacks. So I decided to encorporate them all into one design, thus creating the Commodore 128 40/80 Column Video Adapter.


1541 Diagnostic Cartridge - World of Jani: I have repaired a fair amount of drives, and every time I find myself loading a test or a diagnostic software from disk. This is a bit of a contradiction since the drive being tested, or repaired, might not even be able to load a program. I also have a variety of tools for different purposes and wanted to have everything in one place. This is why i created a 1541 Diagnostic Cartridge.

1541 Ultimate-II: The '1541 Ultimate' is a storage solution for your Commodore C64 and C128 home computer. This piece of hardware implements a 'real' 1541 diskdrive for Commodore computers. There are two versions of this board; the 1541 Ultimate-I and the 1541 Ultimate-II. The 1541 Ultimate-I uses an SD-card or MMC-card to store the floppy disks, while the 1541 Ultimate-II uses MicroSD and USB pen-drives. Both the 1541 Ultimate-I and the 1541 Ultimate-II contain a replica of all the necessary hardware to be fully compatible with a real drive.

Commodore 64 Guides: Having recently returned my Breadbin to perfect working order, I also wanted brand new copies of the C64 User’s Guide, and Programmer’s Reference Guide to complete the set. I could have simply printed one of the scans of these guides from the internet but where is the fun in that? In truth, I have found all these scans somewhat disappointing - very often indistinct and not always complete. Instead, I did the only sensible option: I re-wrote them from scratch using my copies of the originals as source. I reconstructed every graphic (including front and back covers), every register map, every block diagram, every table and every paragraph to have a pristine final result.

PLA16V8: The PLA16V8 is a GAL PLA replacement for the Commodore TED series computers (such as the Commodore 16, 116 and Plus/4) that I did design after the succes of the PLA20V8. In a TED based computer, the most common point of failure is the 8501 CPU. Therefore the shortage of PLAs is not as severe as for the Commodore TED computers, it is easier to find an original PLA than for the Commodore 64. That said, the PLA in the Commodore TED series computers can fail and you may want to replace it with a more available component. This is now available. the PLA16V8 is ready to service you!

PLA20V8: The PLA20V8 is a PLA that consists of two GAL20V8B chips from Lattice Semiconductor. The GAL is a programmable logic chip that looks a lot like the original PLA: It has an AND array, followed by an OR array. Depending on the mode of the GAL the signal then can go through a flip-flop, which the PLA does not have, but this flip-flop is bypassed in the so called “simple” and “complex” modes, which makes the chips rather close to a PLA, perhaps the closest possible chips to a PLA you can get. We need two GALs, because we can't fit all the logic in a single GAL.

Ray Carlsen's Home Page: This site is dedicated to users of 8 bit Commodore Computer hardware. The information herein is listed in “directories”.

Hewlett Packard (HP)

EBTKS: This project started off as an attempt to repair the tape drive of an HP-85A desktop computer. Most of these tape drives (maybe all) have failed because the rubber capstan that moves the magnetic tape in the DC100/HP98200A cartridges have either disintegrated or turned into goo. My companion web site documents my Repair Adventures . Eventually I decided that the repair of the tape drives and the tapes was a lost cause, so I decided that I would design a Solid State Tape Drive replacement that would be compatible with the existing HP85 operating system, and be responsive to all the same commands. I discussed this with my long time friend Russell Bull, and together we have co-designed the hardware and the firmware to make it all work. During our development work, we turned to Everett Kaser for guidance and he soon joined our team and is responsible for the AUXROMs, which added extensive functionality in the form of over 70 new keywords. Welcome to the PA RISC/Linux project archive!

Hewlett Packard Series 100 FAQ

HP 9825: Now vanished into the mists of time and computer evolution, the Hewlett-Packard 9825 desktop computer was way before its time. In many ways, the development of the HP 9825 and its brethren marked a significant turning point for the computer industry. It foreshadowed the PC revolution fully five years (that’s 50 years in computer time) before the IBM PC burst into existence in 1981.

HP Collection: HP-Collection shows vintage Hewlett Packard calculators and their accessories. There is no forum on my site, because there is a frequently used one on the MoHPC. site.

5150CAXX: That’s right – the very first IBM Personal Computer, the IBM 5150 – a business-oriented machine and a hallmark platform that started it all, shipped along with an integrated cassette port. Too bad it could only be utilized through the cassette BASIC contained in ROM… Or shall we say thankfully? Yes, this interface was abandoned soon after, for obvious reasons. But let’s fast-forward 40 years: reviving this legendary machine today, why don’t we give the cassette interface a go… in DOS?

Included is a lot of new material and almost all new pictures previously unavailable anywhere on the internet. As in depth as this could be, its focus is on aspects of collecting such as variations in labeling, comparisons of different versions and information specific to packaging. Links to the Vectrex Wikia are available for futher information as well as a section for some of the developer's websites and newsfeeds to stay current on recent releases as they happen. Enjoy!

VecFever: Since the VecFever is my development tool to create Vectrex cart, it should come as no surprise that I have created quite a few over the years. All the arcade emulators exist also as standalone cartridges – more than two dozen by now. I have build a few odd things over the years – like a thermometer cart., a clock, a 4096-byte game (‘2048’) which could have been produced back in the day. A nice testrev cart. with a voltmeter. Several games of my own. Still, my intention remains to have everything running on a VecFever since I do not want to build a lot of standalone cartridges. Some things need a VecFever to run anyways – like the video or audio players.

vectrex-elite: Most people would say that Protector LE is the Holy Grail of the Vectrex. Some would say that VeCaves is the rarest game ever made for it. Here's a number of games you might not have even know existed. These are the most elite carts and releases for the Vectrex.

64drive by Retroactive: The Ultimate N64 Development Cartridge. As a big N64 fan, a few years ago I wanted some way to try out my homebrew on a real console, play translations, and just to mess around in general – but from looking at all the other solutions on the market there appeared to be tons of room for improvement and I started to make my own. After a lot of work and several years of iteration since then, what you see is the result. It's an extremely high quality product used by hobbyist and professional developers alike.

GB Studio: GB Studio began as number of disconnected scripts and tools which were eventually used to create Untitled GB Game, a game built in one week for Bored Pixels 3, a pixel art game jam where the theme was “Game Boy”. After completing the jam I realised that with a bit of work I could get the tools into a state where they could usable by other people, maybe even by people who had never made a game before. This application is the result of that effort, hopefully you find it intuitive and fun to use.

Olivetti Programma 101: The Olivetti Programma 101 is an early desktop programmable calculator. It was developed in the years 1962-1964, and launched in the States in october 1965, with the first units being shipped a few months later. It had a very large success, due to its relatively modest price ($3.200) and in a few years about 35.000-40.000 pieces were sold. It went on being sold for a few and was still in large use at the beginning of the '70s, when it offered a viable alternative to larger computers.

PalmDB: PalmDB is focused on preserving the earlier days of Palm; its apps, and its operating system. By the late 2010s, most websites for distributing Palm software had shut down or simply removed the content in favor of more modern alternatives. Although it is said the internet never forgets, for a time, Palm's history was in grave danger of being lost. Recognizing the threat, PalmDB was founded in 2018 with the intent to gather what remained and bring it back online. But in the end, it became so much more.

Dilwyn Jones Sinclair QL Pages: Welcome to Dilwyn Jones's QL information and PD software download pages.

divIDE: divIDE is an ATA (IDE) interface by Pavel Cimbal, which takes your ZX Spectrum computing to a whole new level. As the time takes its toll on ageing media such as audio tapes or diskettes, many ZX Spectrum enthusiasts simply stick to emulation for better reliability and comfort. With divIDE you can put your software collection to a hard disk, CD-ROM or even CompactFlash card and experience your favourite games, demos and utilities the way the were meant to be run - and even better. Using existing firmwares, many users find their Speccy box again a live platform - time for you to make the switch? ;]

Immortal ZX Spectrum games: The ZX Spectrum can boast some 15 thousand titles, which is about ten times more than what is currently available for either GBA or NDS alone. This is quite a lot of games to choose from. To put it into perspective, if you try out one title each day, it will keep you occupied for more than forty years. So, where do you start?

OqtaDrive: OqtaDrive emulates a bank of 8 Microdrives for use with a Sinclair ZX Spectrum with Interface 1, or with a Sinclair QL. The goal is to functionally create a faithful reproduction of the original. On the Spectrum/QL side, operating the emulated Microdrives should feel exactly the same as using the real thing. So by definition, it does not try to compete with more “modern day” mass storage solutions for Spectrum and QL.

Planet Sinclair: The Web's biggest Sinclair-related archive.

POKEs Database for ZX Spectrum: This is a collection of cheat codes (infinite lives, bullets, level warping etc.) for more than 2900 games for ZX Spectrum microcomputer. The main source for the codes in this database is the website which is run by Gerard Sweeney. The purpose of the database is to simplify entering codes in games as much as possible. The .pok format is supported by many popular Speccy emulators for all platforms and you can even enter those if you have got a DivIDE interface along with a real ZX Spectrum machine.

QL-SD: Originally I only wanted to make my personal QL-SD work with my GoldCard. In the end that was quite a lot of work and as there are no new QL-SDs produced I created my own version of it. Then I put a lot more work into the software, too (based on Wolfgang Lenerz excellent work). Here are the supporting files and documentation.

The Future was 8bit - divMMC Future: The best just got better, the jumperless divMMC Future already works with more Speccys than the rest, now works with even more marginal machines. For those of you that don't know, divMMC (or the older divIDE) devices let you load & save .TAP images etc directly into your Speecy from SD card.

The Microdrive Hardware Emulator: The vDrive is an external Microdrive hardware emulator for the QL, or the Spectrum with Interface 1 expansion. It simply connects to, and is powered from, the existing Microdrive bus. Due to differing connection requirements, there are two versions of vDrive. The vDriveZX is for the Spectrum and the vDriveQL is for the QL. Check out the ZX and QL pages for more details. To complement the vDriveQL there is also the vMapQL which is a configurable hardware device for translating Microdrive addresses. See the vMap page for more info.

Wonderful Dizzy: Dizzy and Pogie rushed for shelter in their house as a fierce wind approached. The wind whirled around their house ripping it from the ground and taking them soaring up into the heart of the cyclone! They awoke when the house came crashing down with a bump and a scream! Opening the door they discovered they were in a new and magical land called Oz. A land ruled over by four witches - the good witches of the North and South and the wicked witches of the East and West. Only, now Dizzy appears to have killed the Wicked Witch of the East making the Wicked Witch of the West furious and in a rage she snatches Pogie and disappears in a puff of smoke! Dizzy must rescue Pogie and find a way home and the answers appear to lie with the Wonderful Wizard of Oz in the Emerald City. Along the way, Dizzy meets a brainless Scarecrow, a heartless Tin Woodman and a Cowardly Lion and many other characters who all need his help, many of whom seem oddly familiar. This is a new adventure designed 100% by The Oliver Twins and inspired by the classic book - The Wonderful Wizard of Oz.

ZX SPECTRUM 48Kb - DEMOS, GRAPHIC, MUSIC, SPECIFICATION: This is a site dedicated to bestseller computer of 80s first half - ZX SPECTRUM 48K.

ZX Spectrum ROM: Arcade Game Designer: This is a total rewrite of the ZX Spectrum ROM in 16384 bytes of Z80 assembly language. The original ROM contained Sinclair BASIC, which while versatile was not suitable for writing games due to its lack of speed. It was also impossible to type quickly on the machine due to the ROM keyboard routines' insistence that the first key must be released before the second is pressed. This ROM remedies these problems. The ROM contains editors for blocks, sprites, screen layouts, map, objects, text messages and sprite positions. There is a code editor that uses a simple scripting language inspired by BASIC. There is also a compiler to turn the commands into lightning-fast machine code and a game engine that is copied to RAM on initialisation. Games created using this ROM will run on Spectrums with the original ROM and it is easily capable of producing games that would have been of commercial quality in the 1980s and early 1990s.

ZX-VGA-JOY: ZX-VGA-JOY is ZX Spectrum interface for connecting any kind of VGA monitors, Kempston joystick and computer reset. It supports 7 screen modes: 640×480 @ 50Hz, 640×480 @ 60Hz, 640×480 @ 75Hz, 640×480 @ 85Hz and 800×600 @ 60Hz with 3 different zooms (paper/border sizes). This interface is not signal converter, it works in parallel with internal graphics IC(ULA) taking video data directly from CPU and provides crystal clear picture on VGA monitors. Also, the picture on VGA monitor is precisely synchronized with PAL signal generated from ULA, so games that are relying on ULA timing looks as they should. ZX-VGA-JOY is compatible with all Sinclair and Amstrad ZX Spectrum models and probably with a number of clones. It is not necessary to do any modification on the original computer as long as the expansion port is functional on pins used by ZX-VGA-JOY.

CoCoVGA: CoCoVGA is an FPGA-based hardware enhancement for Motorola 6847 VDG-based microcomputers from the 1980s, including the early TRS-80/Tandy Color Computers. It enables VGA video output as well as a few other video improvements.

CoCo SDC: The CoCo SDC is a home-brew project for the TRS-80 Color Computer (CoCo). Darren Atkinson began development in 2009. Originally intended to just add floppy disk controller emulation to a Drivewire connection, that idea expanded over time to include emulating a floppy controller for an SD-card reader with Drivewire server access. The CoCo SDC aims to solve the compatibility problem by combining the traditional “software hook” approach with a robust emulation of the floppy controller in hardware. This dual mode implementation provides excellent performance for the majority of software which “plays by the rules” while adding a high degree of compatibility with those titles that employ floppy-based copy protection schemes or simply choose to use their own floppy drivers.

Information from these links includes product descriptions, catalog numbers, pictures, prices, operations, hardware, software, etc.

mini-MPI: At one time, Radio Shack offered a bus expansion for their Color Computer line. Called the Multi Pak Interface, these are usually referred to as MPIs by users. MPIs (of which there are several variants) all plug into the CoCo cartridge port, and provide four slots to plug in program paks, and other cart port based accessories. Several third party expansions were offered as well back in the day, and can be spotted in ads in old magazines devoted to the Color Computer. This page describes my efforts to put together a two slot MPI, for people that are looking for just one additional slot, in as compact a package as possible. Original MPIs are large and take up a lot of desk space.

TRS-80 Diagnostic ROM: This project was born out of a broken TRS-80 Model 3 that I was working on. I could not tell if the system was even “executing code,” so I used an early version of this ROM to help diagnose the problem. Please know that the main goal of this ROM is to test the functionality of the video RAM (VRAM) and the dynamic RAM (DRAM, system memory.) It does not test any other component unrelated to those two subsystems. If a TRS-80 has good VRAM and DRAM, it should boot into basic where you can then run further tests.

Wang Labs

Wang 1200: The Wang 1200 was an unsuccessful product, at least in terms of Wang's original expectations, but it played an important role in the history of Wang Labs. It is also interesting in the more general context of the development of word processing as a standard part of office automation.

Wang 2200: Born before the era of the microprocessor, the Wang 2200 CPU was built using a couple hundred TTL chips spread over half a dozen boards, and housed in a heavy steel “suitcase.” Its BASIC interpreter was written in microcode; there was no machine code that a user could access, unlike microcomputers that would come years later.

Wang 3300: Before Wang made the incredibly successful 2200 series of computers, they had attempted the job at least twice before, with the Wang 4000 Computer System and the 3300 BASIC computer. Where one draws the line between their programmable calculators and their calculating computers is debatable.
