Here's a relic from IBM's first SCAMP, a large ring binder (16 rings!) from
Hursley, early 1960s. Unfortunately no SCAMP diagrams inside but to this

Cool!
It even works.
I'll have to look that pro380 technical book up, I've always referred to
my XT100 documents but those were pre-release for the Pro/350.
Now for the real 50k question: Does the AVO socket next to it take the
same board format for the 8 bit color video memory? Anyone have a
picture of the AVO

Possible. I see that Xhomer includes a version of RT11, and when I
looked at that I saw that the .MAC files for the DZ and whatever the
disk is (DY?) drivers appear to be there. So it might not be impossible
to write the drivers in M+ based on that.
Maybe.

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
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.

Copied all the files onto my Gotek, it's SO EASY to just turn a dial to
select a disk!
Anyway, loaded all the files, but when I try to run them it says it's
missing PROF77 Common. My guess is that's the same block as F77OTS, but
how does one load a common block with a different name? I
