CompuPro - 451A CPU286
This was CompuPro's (or by then
Viasyn's) final Intel
IEEE-696 CPU
board. They did make an S-100 board with an 80386 CPU. However was not fully
S-100 compatible since it did have to make use of a secondary bus connector at
the top of the board edge to support high speed 32 bit communication with memory
located on separate S-100 Boards also fitted with this connector. The
board was introduced in July 1983.
I have no information about this
interesting looking board. I cannot locate the manual for this board. If you
would like to provide one (or the above 386 board) for others to read. I will be delighted to enter it here.
It appears there was two different
arrangements of this 286 board board. There was an earlier board shown
below where the chips were arranged differently. Note, it was
quite common to find the voltage regulators removed from these late Viasyn
S-100 boards where a regulate +5V was put on the motherboard instead of
+8Volts. Be careful not to put these boards into a "regular" S-100
system.
