/**********************************************************************
PolyMorphic Systems 16K RAM Card
This is a mostly straightforward S-100 dynamic RAM board using
the Intel 3242 controller to generate refresh timings. The one
slightly unexpected IC on this board is a SN74LS283 adder, which
allows the RAM to be addressed in a contiguous block beginning at
any 4K boundary.
