Jerome Fine replies:

I think I have a working Pro-350 and would likely appreciate having
more memory. However, my primary focus is with an actual PDP-11
on a Qbus, so if these boards are requested by someone else, please
send them to a warm home. Sometime next year, I will have to go
through my collection of PDP-11 hardware and sort out what I want to
keep for the long term. I would appreciate some guidance on what is
reasonable to keep for at least a 20 year period.

Sincerely yours,
