You could suggest this to Unicomp -- they must already be making one for
their USB Model Ms, so perhaps they'd be willing to sell the board
separately. I'd buy a couple.
Based on what I see at their website, it seems that their Model M is
inferior to the Old Reliable part number 1391401. This suggests that
whatever USB controller board they're using, it won't fit in the older
boards. Furthermore, according to Wikipedia, none of the keyboards
currently made by Unicomp have detachable cables. The PCB I'm rolling
around in my head would.
One thing I'm unclear about with this idea is how to store the program.
Are there any single chip OTP microcontrollers that use fuse type memory
as opposed to flash, UV, or some other sort that eventually goes bad?
