Cromemco 16K KPR ROM Board
This was the next extension of the
popular 8K Bytesaver.
![8K PROM](16K Prom.jpg)
The board provided space for 16 2708
type 1024-byte erasable PROMs. The card could also be used with 2708 compatible
ROM memory ICs, such as the 2308. Like other Cromemco memory cards, the 16KPR
will operated at 2 or 4 MHz (user-selectable), without wait states, in the usual
sequential addressing class of operation. The 16KPR included Cromemco Address
Anticipation circuitry, which allows virtually full speed operation at 4 MHz.
The 16 KPR also had Memory Bank Select, a feature that allows expansion of
memory space beyond 64K bytes. With bank select, memory space may be
organized into 8 banks of 64K bytes each. Direct Memory Access Override was
another feature of the 16KPR that allows a DMA transfer to take place between
any addresses in memory without regard to residence in a particular memory bank.
The 16KPR provided ideal EPROM support for the Cromemco Z-80 CPU card.
The manual for this card can be obtained
