Answering my own question: Yes it does work. My Pro/380 now sees 320kw of memory instead of 256kw.

Now to buy some sockets and upgrade these boards to 256kw each. One can go in the Pro/350 and the other plus the memory boards should take my Pro/380 to almost 1kw.

I wonder if the CTI memory boards can be upgraded from 64k chips to 256k chips. Probably would require reprogramming the ROM as well on the board. Hm.

Meantime a question: The pro/350 has two memory daughter cards on the board. The Pro/380 appears to have a spot on the motherboard that takes the same size card. Can one use a Pro/350 internal memory board (not CTI) on the Pro/380 motherboard?

Wondering before I plug this in....

  Sounds like these may the long lost P/OS drivers. Contact Jörg Hoppe at RETROCMP - he's been scanning in a lot of DEC fiche of late. http://retrocmp.com/
