This code is in Intel HEX format. It can be burned into 2716 EPROMs and just plugged into the Processor card. No special wiring needed or switch changes. I tesed this code with 100ns EPROMs but have not tested it on slower EPROMs. 

The part numbers of the ROMs are:
U8 1818-3742
U9 1818-3741
U10 1818-3743
U11 1818-3744
U12 1818-3747
U13 1818-3746
U26 1818-3749
U27 1818-3748
U28 1818-3745

A note about the processor and support chips. It may not be obviously but the processor family is the Fairchild F8 (3850) family, which is nearly impossible to get anymore so be careful around these parts.
