Hello, all:
I was just looking at the schematics for the display/control board
for the Altair 8800 and saw that there is a 1702 EPROM on the board. The
lowest 4-bits of the EPROM's address bus are connected to a 7493 binary
counter and the highest 4-bits are connected directly to the address bus.
What's the purpose of the EPROM? Did the front panel have some
intelligence?
