Howdy,
I'm currently putting together a simulation of the "SacState 8008
machine" (the machine described at
http://www.digibarn.com/stories/bill-pentz-story/ )
This computer was a series of custom cards that plugged into a
Tektronix 4023 terminal, and used the 4023 for I/O. Therefore in order
to simulate the SacState 8008, I need to start by emulating the 4023
terminal.
Having a copy of the character generator ROMs would help a lot with
making that emulation authentic.
According to the 4023 service manual, the chargen ROMs are:
Upper Case ROM A - part number 156-0147-00
Lower Case ROM A - part number 156-0401-00
Optional Ruling ROM B - part number 156-0401-00
Would anyone have a dump of any/all of these chargens?
Regards
Jonno
