I was talking to a former co-worker who worked for McDonnell Douglas
Network Systems Company who owned Tymshare at one point, and he had a
picture of a 1mb memory from one of the nodes.
He passed along this link to the manual for the node processor.

Wondering if any survive and are working.
It was a 64 bit microword, 32 bit data path TTL logic type machine,
similar to one of the ones I worked on pre-bitslice days. Also wonder
if the microcode survived.
Date on the drawings was 1978 though this manual set is coded as April 1985.
thanks
