This feels like deep water to me. I 'd like to develop a small keyboard that will send to the PC specific characters when buttons are pressed.

In short it will be a stripped keyboard with much less keys (F1-F12, number 1-8 and another 8 capital letters).

Can PBP support such a function? Found for mouse but not a working keyboard emulation.

Prefer to use 4550 or 45K50 chips.
