Amico 2000 (ITA): Durante una discussione con amici sul newsgroup it-alt.comp.folklore è nata l’idea di ricostruire una vecchia macchina italiana. Molti hanno già ricostruito computer storici ma nessuno ha mai ricostruito macchine italiane. La scelta è caduta sull’Amico 2000 perché è una macchina che molti desiderano ma nessuno possiede, ci è sembrato giusto scegliere una macchina ormai scomparsa che rischia di essere dimenticata.

Briel Computers: Here you will find many fun and exciting kits for you to solder together. Our goal is your fun. Now you can enjoy assembling circuit board kits just like the computing pioneers did in the 70's and early 80's. We try to make low-cost fun kits for everybody.

CARDIAC: Back in the 1960's and early 70's Bell Labs made some very sophisticated educational kits available to high schools and colleges. Designed for classroom use, they included wonderful manuals written by some of Bell Labs best minds. One of these kits, introduced in 1968, was CARDIAC: A CARDboard Illustrative Aid to Computation.

C64 Reloaded MK2: The Commodore 64 Reloaded MK2 is a C64 Motherboard for building a C64 on your own. The board is shipped with empty ZIF sockets for the key chips such as CPU, port chips, sound/video chips. All other components are already assembled and pre-tested before shipment.

EDSAC In Your Pocket: EDSAC (Electronic Delay Storage Automatic Calculator) was an early stored program computer that first became operation in 1949. Its design and construction was lead by Professor Maurice Wilkes at the University of Cambridge. Seventy years later, a machine that took up a room can be simulated using a cheap micro-controller in a device that fits in your pocket. This project is a practical demonstration on that. But mostly it's just a bit of fun.

KIM Uno: A DIY clone of the KIM-1. The KIM Uno is a small “open-source hardware” project to build a replica of the classic 1976 KIM-1 computer. It doubles up as a 6502 programmable calculator. It costs about $10 in commonly available parts (board & parts without case or power supply), but provides a faithful KIM-1 'experience'. An atMega328 (Arduino Pro Mini, actually) mounted on the back of the board contains all the logic and memory.

MEGA65: The 21st century realization of the C65 heritage: A complete 8-bit computer running around 50x faster than a C64 while being highly compatible. C65 design, mechanical keyboard, HD output, SD card support, Ethernet, extended memory and other features increase the fun without spoiling the 8-bit feel. Hardware designs and software are open-source (LGPL).

Minstrel ZX80 Clone: This is a PCB which can be used to build a ZX80 clone. It is built in the form factor of the ZX81, so can be used as a replacement board for a broken ZX81. The design follows the original ZX80 design with only a few changes. The RAM has been upgraded to 16K, and the ROM socket can take a 2764-27512 EPROM with 1 to 8 ROM images which are jumper selectable. The video output has been improved and is now a composite video signal rather than the version generated by the original ZX80 and early ZX81 boards which were missing one part which affected the black level on modern TVs.

MIST board: The MIST board was designed to implement classic 16 bit computers like the Amiga, Atari ST(E) or the Apple Macintosh (and even early 32 bit computers like the Acorn Archimedes) as a System-on-a-Chip using modern hardware. But it equally well supports 8 bit systems like the Atari XL, ZX81, ZX Spectrum, C64, Atari VCS, Atari 5200, Colecovision, Apple II, Sega Master System, Nintendo Gameboy, Nintendo NES, Odyssey2 and many many more …

Mistica FPGA16: MISTICA FPGA16 is a FPGA computer board able to implement classic systems like Spectrum, Amstrad, MSX, C64, Atari ST, Amiga etc. 100% compatible with MIST FPGA (cores and firmware). Has video connection VGA, RGB, composite video, SVideo, audio out RCA and stereo jack, audio in EAR for audio load.

MiSTer: MiSTer is a port of well known MiST project to a larger FPGA and faster ARM. MiSTer provides modern video output through HDMI (VGA and analog audio are still available on daughter board). It's based on Terasic DE10-nano board.

Omega Home Computer: This project is an open source implementation of an MSX2 compatible computer. The project is built using a combination of 1980's era components - Z80 CPU, V9958 VDP, AY-3-8910/YM2149F PSG, 8255 PPI, 7400-series logic, and some newer components, such as 512 KiB SRAM and 512 KiB Flash ROM and a few simple programmable logic devices (ATF16V8B SPLDs).

OpenTendo: An Open-Source HardWare (OSHW) recreation of the original 1985 Front-Loading NES motherboard.

PiDP-11: The PiDP-11 is a modern replica of the PDP-11/70. The PiDP-11 wants to bring back the experience of PDP-11 Blinkenlights, with its pretty 1970s Rose & Magenta color scheme. On a more modest (living room compatible) scale 6:10, with faithfully reproduced case and switches.

PiDP-8/I: The PiDP-8/I is a modern replica of the 1968 PDP-8/I computer. Project goal: to create a faithful but low-cost replica of the 1968 PDP-8/I. Operated through the Blinkenlights front panel, it should evoke the user experience from the past. It should also replicate all stages in the PDP-8's development.

RCA CHIP-8: CHIP-8 was originally developed by RCA Labs (1972) to allow users of low cost microcomputers to design their own video game programs without the tedious task of writing assembly language programs. RCA's original Computer was called the Cosmac VIP. It used an 8 Bit processor (1802) running at 1.76 MHz. Sound consisted of one fixed tone, and data storage utilized a cassette recorder. Our Classic CHIP-8 Computer has a Flash based Interpreter that is resident within the boards Operating System, and is much more HIGH Tech than the computers of the past…

REMEMOTECH: REMEMOTECH is a modern-day re-implementation of a Memotech MTX/FDX/SDX compatible computer. It implements enough hardware to allow it to run MTX BASIC, various MTX games and CP/M.

snark-barker: The Snark Barker is a 100% compatible clone of the famed SB 1.0 “Killer Card” sound card from 1989. It implements all the features, including the digital sound playback and recording, Ad Lib compatible synthesis, the joystick/MIDI port, and the CMS chips (which are actually Philips SAA1099 synthesizer devices).

"SixtyClone" Commodore 64 Replica PCBs: These are replica Printed Circuit Boards (PCBs) derived from the Commodore 64 8-bit computer. The boards were created to allow Commodore 64 computers that had damaged or faulty PCBs to be successfully repaired. This can be achieved by moving all components from an original board to the replica board, or even replace some parts with more modern alternatives.

Tandy / RadioShack TRS-80 Model 1clone

The Altair-Duino: This is a cycle-accurate recreation of the original Altair 8800. What does that mean? It means the Intel 8080 CPU is emulated, as is some of the basic I/O (disk drives, serial ports, etc.) but everything else is REAL Altair machine code and CP/M that was created more than 40 years ago!

The µKenbak-1: After the success of my Altair-Duino kit, I knew my next project would be something more esoteric. It needed blinking lights of course, and had to have a great history. The Kenbak-1 fit that bill. I studied all information I could find on the Kenbak-1, but I knew I could never actually use one (it’s estimated there are 17 still in existence, with a minimum price of $25k!).

WDR-1-Bit-Computer (DEU): Der WDR-1-Bit-Computer ist ein auf dem MC14500 basierender Lerncomputer. Die geringe Komplexität und die übersichtliche Konstruktion ermöglichen einen leichten Einstieg in die Grundlagen der Computertechnik.

ZX Spectrum Next: The Spectrum Next – an updated and enhanced version of the ZX Spectrum totally compatible with the original, featuring the major hardware developments of the past many years packed inside a simple (and beautiful) design by the original designer, Rick Dickinson, inspired by his seminal work at Sinclair Research.

µGalaksija: µGalaksija started as a tribute to the “forgotten” GALAKSIJA computer, designed by Voja Antonic in the early 80's. The idea was to use pure FPGA design to achieve near 100% hardware compatibility sticking as much as possible to the original design, and maintain 100 % software compatibility (even when changing/adding something to the design). And, we did it!
