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.
