AT2XT Keyboard Adapter: A simple adapter to enable the use of a modern PS2 keyboard on IBM XT computers.

ATX2AT Smart Converter: The ATX2AT Smart Converter plugs on a standard 24-pin ATX PC Power Supply and acts as an intelligent protection device for old retro-hardware. It can be seen as a couple of programmable fuses with monitoring capabilities. You can set the current limits and define how quickly it will react to an overpower condition. It was originally designed for vintage PCs (with AT-Style power supply), but it can also work with old Macintosh as well as many other 70s/80s/90s computers, consoles, etc.

drem: The DREM (DRive EMulator) is an FDD/MFM/RLL HDD emulator or MFM/RLL SSD. Replace old Floppy and MFM/RLL drives with SD card!

FlashFloppy: FlashFloppy is a floppy-drive emulator for the ubiquitous Gotek hardware. Connect to retro machines just like a real floppy drive but use disk images on a modern USB stick!

FluxEngine: The FluxEngine is a very cheap USB floppy disk interface capable of reading and writing exotic non-PC floppy disk formats. It allows you to use a conventional PC drive to accept Amiga disks, CLV Macintosh disks, bizarre 128-sector CP/M disks, and other weird and bizarre formats. (Although not all of these are supported yet. I could really use samples.)

GoTek Emulator: We have manufactured different versions of floppy to USB emulators keeping in mind the needs of the industry. These floppy to USB emulators have been designed so smartly that they use same traditional floppy drive 34 pin channels and same +5 volts DC voltage. The size of these floppy to USB emulators was also kept same, so that it can fit into same place. These emulators have practically started the end of and old era related to floppy drives.

HxC2001: Universal Floppy Disk drive replacement/emulator solutions. The HxC Floppy Emulator project main idea is to completely replace the floppy disk drive by an electronic device. This electronic device emulate the floppy disk drive behavior and functionnalities. The HxC Floppy emulators are designed to be very versatile and to support a large variety of computers / keyboards / samplers / CNC machines at a reasonable price. The HxC Floppy Emulators support most existing floppy formats.

kbdbabel: Welcome to kbdbabel “keyboard-babel”, open source keyboard protocol translator project.

KryoFlux: Welcome to the home of KryoFlux, the renowned forensic floppy controller available today. KryoFlux is a USB-based device designed specifically for the reliability and precision needed to acquire reliable low-level reads suitable for software preservation.

OpenFlops: OpenFlops is an Open Hardware Floppy Disk Drive emulator/simulator. It is designed to run the FlashFloppy firmware, which gives it several improvements over the original Gotek.

pcxtkbd: PS/2 → PC/XT Arduino based Keyboard adapter.

SCSI2SD: SCSI2SD is an emulator for old SCSI hard drives. It allows replacing one or several old broken SCSI drives with a SD memory card.

Teletype RS-232 Adapter: Plug and Play RS-232 Adapter for Teletype Model 33.

Unijoysticle 2: Use modern bluetooth gamepads in the Commodore 64, 128 and others.

USB-teletype: This is a compact USB current loop serial adapter on a 1.6 by 1.4 inch pc board. It connects to a computer running Windows, Mac OSX, Linux, Android, or probably anything else via a USB Mini-B connector, and presents itself as a USB serial port, while the other end connects directly in series with a teletype loop (or pair of loops, if full duplex). Data is relayed bidirectionally between the two. It does not generate loop current itself, so a loop power supply with fuse is needed if not already present.
