Cromemco 32K Bytesaver S-100 EPROM Programmer Board 1978 Altair IMSAI


From s100computers dot com where there is a manual also.


The board provided space for 16 2716 type 2048-byte erasable PROMs. Like other Cromemco memory cards, the board operated at 2 or 4 MHz (user-selectable), without wait states, in the usual sequential addressing class of operation. The board had Cromemco style bank select capability allowing memory expansion beyond 64K. ROM shadowing allowed external memory to overlap portions of the 32K bytesavers address space. PROM burning was precisely controlled using an onboard pulse with control circuit.
