Back over 2 years ago Andrew and I put
together an S100 bus “4MB Static RAM board” with IEE-696 8/16bit data carrying capacity.
This board has proven to be very popular and very reliable. Over 30 boards
were already made and distributed to users. However in our quest to
install 16 and 32 bit CPU’s on the S100 bus, 4MG has started to look like a
limitation. The S100 bus is capable of addressing up to 16MG. For this 4
of the above boards would be needed.
Over the past few years the price and availability
of high speed static RAM’s have changed dramatically. It is now feasible to place 16MB of high
speed IEE-696 8/16 bit RAM on a single board.
A prototype of this board is described here:-
It’s unclear what the interest is in people
obtaining a “commercial style” bare board like this. I will definitely be
getting 4 for myself. If you absolutely need one sooner rather than later let
Andrew know we can include you in the early “first batch”.
Otherwise stay tuned for a later group purchase by (hopefully) a group member
that will organize a larger purchase - at a lower price. If there is group member right now that could
coordinate a purchase all the better.
