 Also the Mitsubishi 41000 is a 1-Mibit part, so the module is 1MiB (or 
2MiB if double-sided).  So you just need to figure out which DEC systems 
used such SIMMs.  If 2MiB, then DECstation 2100/3100 might be a candidate 
and these would be MS01-AA, also working with DECstation 5000/1xx and 
Personal DECstation 5000/xx systems (and probably some VAX machines too).

 BTW, nice talk at FOSDEM 2020, I was there. :)
