Back to the original topic, someone suggested the memory would fit a DECstation 2100. They were right! I have done a short post about it https://robs-old-computers.com/2020/04/04/memory-for-a-decstation-2100/. Thanks for the suggestion :-) Regards Rob On Fri, Apr 3, 2020 at 5:04 PM +

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
