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
