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 will allow use of Cherry MX keys, or Futaba MD-4PCS (aka eorge 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. -Goals for the keyboard: - -- Drop in replacement for Ohio Scientific polled keyboards --- Done: drop in for OSI 542 (untested). --- Done: keycap set available --- To do: module for advanced 542B/C features - -- Drop in replacement for Apple II keyboard ---To do: Add-in ASCII module required ---To do: Add power light and power light cover ---To do: Special Apple keycaps needed. - -- Standard ASCII parallel keyboard --- Done: Keycap set available --- To do: Add-in ASCII keyboard +This keyboard project so far consists of: +1. 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, or an OSI case. +1. A keyscan/decoder interface module that can output parallel ASCII, and can be adapted for other protocols. +1. An OSI-compatible interface module.
