## Unified Retrocomputer Keyboard Project
|
|
|
|
This project aims to provide a unified collection of keyboards and encoders for vintage computers, with modular design to reuse as many elements as possible across the designs.
|
|
|
|
Home computers of the 1970's typically either polled a switch matrix, or interfaced to a parallel ASCII keyboard via a parallel port.
|
|
|
|
The keyboard allows use of Cherry MX keys, or Futaba MD-4PCS (aka George Risk KBM-01-01) keys.
|
|
|
|
The keyboard is designed using KiCad in order to be the most useful for anybody wishing to modify the keyboard for more specific uses, or to add to the project.
|
|
|
|
### Capabilities so far:
|
|
- Replacement keyboard for OSI computers
|
|
- Replacement keyboard for Apple II/II+ computers
|
|
- Replacement keyboard for the Sol-20 computer
|
|
- Generic ADM-3A/Teletype style keyboard
|
|
- Apple I keyboard (multiple styles)
|
|
|
|
### Coming soon:
|
|
- Replace encoder board on Apple II/II+ keyboards
|
|
- Convert an OSI 542 keyboard into a generic ASCII keyboard
|
|
- Replica for Knight keyboard
|
|
|
|
### This keyboard project so far consists of:
|
|
- A classic retro-style ASCII keyboard, modeled after the ADM-3A keyboard, which
|
|
can be also be populated to fit perfectly in an Apple II/II+ case (with corresponding Apple II keymaps), or an OSI
|
|
case (with OSI adapter).
|
|
- A Sol-20 compatible keyboard.
|
|
- Keyscan/decoder interface modules that can output parallel ASCII, and can be adapted for other protocols.
|
|
- An OSI interface module, to connect the classic keyboard to an OSI computer.
