Is this a 1 Meg or a 4 Meg board? I'd be interested to see a picture, since
I have the chip, (oddly, it came in with some BBC scrap), and a 1 Meg 32016
board I re-cased, (it came from an earlier Cambridge workstation that
someone had broken for spares)..

I take it that the MMU is fitted as IC2. Is IC16 fitted too? and are there
more than 2 links fitted on the stack to the left of where IC 16 would go?

Mine is fitted with 32 x 256 bit RAM I've never seen a circuit diagram, and
would be interested to know if it was possible to upgrade without the much
bigger board, (there seem to be quite a few RAM links). I have saved quite a
bit of DRAM from that era for repairs and rebuilds, though my HP 9823 repair
has eaten quite a lot of the 16 K RAMs.

Hope it all works; very few 32016's seem to have survived.
