## Universal ASCII Keyboard
|
||
|
|
|
||
|
|
This project aims to provide a (near) universal ASCII keyboard for vintage computers. 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 will allow use of Cherry MX keys, or Futaba MD-4PCS keys.
|
||
|
|
|
||
|
|
The keyboard supports diodes per-switch for true N-key rollover, or
|
||
|
|
per-row (like the OSI).
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
Goals for the keyboard:
|
||
|
