Cromemco 8K Bytesaver-II
The Cromemco Bytesaver could accommodate
eight 2708 UV erasable EPORMS. It was a follow-on to their Bytesaver board with
the addition of Cromemco style bank select capability.
Like the origional Bytesaver, it had an integral PROM
programmer along with a DC to DC power supply to generate the required 12V
programming voltage. They supplied the software as well though the typical
Cromemco Z80 board monitor software had a burn PROM function with this
board. The switch at the top left corner was there to prevent accidental
programming. PROM burning was precicely controlled
using an onboard pulse with control circuit. It did not support the S-100 bus Phantom
line for output (to inactivate othere overlapping RAM on the bus).
