Fulcrum Omni256 -- 256K RAM
This 256K Fulcrum static RAM board was a natural extension
of their then successful "Omniram" 64K
board. The board came out late (1985).
The board of course was completely IEEE-696 compatible. The board could be
located on any 256K boundary. It came factory set for the first 256K of the
S-100 available address space. It handled 8 and 16 bit data
paths per IEEE specs. There ware no issues with DMA because of its use
of all static RAM. When populated with 120 nsec. RAM chips it could be run
with an 8 MHZ bus clock. The board recognized the phantom line and had
a total power consumption of only 4 watts. There was also a battery
backup connection. The board was normally stocked with HM6264LP (8K x 4)
static RAM chips .
