Subject: Not Exactly a BBC Question But...

Hi everyone, it's been a while since my last post, but life has been super
busy. Anyway, I need some help with a simple hardware project. I've just
bought an FM-77 AV 40 SX, but I got it without a keyboard. I have all the
information required to create an adapter to let me use PS/2 keyboards with
the FM, but I just don't have the practical hardware development experience
to turn the information into an actual device. Can someone give me a little
help? I have all the codes that the keyboard sends to the computer for
every single key, as well as the data rate, the repeat timing, and how the
keyboard responds to multiple keypresses, as well as the pinouts. I know
this problem can be solved with a uController or a (C)PLD but I just don't
have the experience with VHDL or Microcontrollers nor the knowledge of the
PS/2 protocol to actually put it together. Can someone possibly help me? I
will post all the pertinant information below:

I know there are more then a few people with FM 77 AV series machines
looking for keyboards, so this could actually make back anything anyone
puts into it. I am capable of assembling any boards (if they are
through-hole that would be even easier ;)) I just need help with the design
side of things. Please, if anyone out there can help me, it would be very
much appreciated. I can't put the FM 77 AV in my museum without a keyboard.
