I have a copy of the DECDirect catalog dating back to somewhere in the
90's, and it runs under W98 on a VM under SuSE!
I search for the 2-5-2 part number with no results, although it has
MS01,MS02, MD42, and MS-62.
I used to have a cross reference to 2-5-2 numbers somewhere and if I
find it I will have another try.,
Sorry!

I also note that the listing just says VS4000 and does not specify a model.
It could be one of 5 different models, all of different speeds: a
4000/60, 90, 90A, 96 or VLC.
Could you just put the DIMM onto a flatbed scanner or something?
The -12 on the chip part number implies 120ns RAM to me. That is slow
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.
