The -12 on the chip part number implies 120ns RAM to

by modern standards -- before EDO came in, PCs tended to take 70ns,
80ns was slow and 60ns was fast. 120ns would be quick enough for a
4000/60 or 4000/90, marginal for a 4000/90a and too slow for a VLC or
4000/96.
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. :)
