Hi at all,
as many will have understood, i'd like to make my BigBoard 1 alive again.
I need for a ASCII parallel keyboard.
Many years ago (exactly 20 ones) I got a old cherry keyboard; I open it and
rebuilt all its rows and colums to be the inputs for a KR-2376 keyboard
encoder.
I had much more time..
I though to realize an economical interface to convert signal coming from a
PS/2 keyboard and convert each codes in parallel standard (data 0 to 7 plus
strobe signal).
Here there is a schematic already suggested
http://eece.ksu.edu/~eece696/beta/digital/A/stop.htm but could it works?
What could be the exact schematic and hardware to use? And at the last is
there anything "ready-to-use" cause I have not much time to spend to build
it?
Thanks to all will answer.
Regards
Enrico
