This is a LED message display controlled by a R6502-11 microcontroller board.
The keyboard is from a Cosmac ELF, modified to run on power supplied from the uC
board. Connectors are a bit flakey, seems to work but for the input.
Unfortunately it's an ASCII keyboard connection, while I was hoping for it to be
just rs232. Unfortunately this makes it a bit difficult to use for my
application, unless I replace the board with a more modern microcontroller.
Still doubting what to do about that a bit.
greetings,
Michiel
