Looking for a parallel keyboard - test-drb@ccmp.vtda.org

 A simple google search turned up:

Note that the website is long gone, but archive.org has it cached away :-)

 Hi
Does anyone have a parallel out keyboard that they

 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).

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
to mate with my BigBoard's keyboard connector. Of course it should emit
the equivalent of the AY5-1015 (if I recall correctly) parallel keyboard
chip as well...
