Yes, that would be great! It would be excellent if it were small, had
a PS/2 connector and a 26pin ribbon header with the following pinout

the equivalent of the AY5-1015 (if I recall correctly) parallel keyboard
chip as well...

Hi
Does anyone have a parallel out keyboard that they
would like to sell to me?
Dwight
Does this mean there might be a small market for a PS/2 to parallel
keyboard converter? I can envision two modes, output only, where ASCII
data and strobe are provided when a key is pressed, and an I/O mode, so
that keyboard commands can be clocked back in.
Multi-key sequences (like F1, etc) would be converted to VT100 keyboard
sequences. Perhaps a few others terminal types would be supported, such
as the TVI950.
Information like Shift would affect the keycode, but would not be passed
along (well, I guess we could, with a mode switch. But normally not.
It'd just look like the keyboard data stream from a serial terminal).
