I did have a quick hunt on the net for IPBs for any of

no luck. manx shows a few service manuals but they had the MS4x numbers.
The look does match MS01-AA though as shown in Figure 5-9 on page 5-16 of
"DECstation 5000 Model 100 Series Maintenance Guide", EK-PM32G-MG-003 (aka
pm32gmg3.pdf). OTOH a single module from an MS01-AA pair is listed as FRU
57-30735-02 there, so it may not be compatible after all.
I have several of MS01-AA modules, but all in remote locations, so I
won't be able to check them anytime soon (given the current situation).
