I've kind of been in a holding pattern waiting for the keyboard "kit" to arrive but no more as it was delivered last week. This is a classic retro-style ASCII keyboard, modeled after the ADM-3A keyboard, which can also be populated to fit perfectly in an Apple II/II+, or an Ohio Scientific Inc. computer. For details check out the Unified Retro Keyboard project.
I was able to purchase the keyboard PCB, a set of Fubata MD-4PCS keys, a stabilizer panel for the Fubata keys, and a set of reproduction OSI keycaps from Dave at osiweb.org. I also ordered an OSI specific encoder which is on backorder.
So I went ahead and assembled the keyboard. I'm not going to detail the process here since it was mostly identical to the work I did on my Sol-20 Reproduction. For details check out:
- The Keyboard Encoder
- Keyboard Construction (Note that the newer keyboard PCB has the discrete diodes and resistors pre-populated on the board. A real time saver. Thanks Dave.)
After adding the OSI Challenger style keycaps this is what I have.
