Hello list,
I've been recently offered a Pro350 unit, depending on whether I can get past my
budget and the wife. :-)
Said unit has 256kB RAM and a 10MB disk, presumably a RD51. No operating system. 4 SLU
async card. VR201 monochrome monitor. F-11 CPU (LSI-11/23).
Some questions I have:
1. What OS can I run on this system? (Yes, I've heard the nightmares of the Piece of
S* O/S). I was thinking in lines of RT-11...if so possible, then where can I get RT-11 for
the Pro350? Is RSX-11 available for the Pro350?
2. Correct me if I'm wrong: Since it's the F-11 CPU, then it'll be limited to
18-bit addressing, therefore maximum RAM supported is 256kB, right?
3. Can I "upgrade" the RD51 with a RD54? Perhaps that depends of the bootROM and
O/S support, right?
Thanks.

You aught to be able to run any pdp-11 operating system except ATT V7 unix(no
supported peripherals), BSD2.11(no I+D), and I don't think mumps will work.
I'm pretty sure you can use at least a rd53.

Definitely not.
A PRO has a completely different (and very badly designed) bus, a
completely different set of peripheral controllers, and even a
different (bogus) interrupt system. It takes MAJOR changes to support
those machines.
P/OS is the original PRO OS. It's an RSX11-M derivative. It may be
that regular 11-M runs as well, I don't remember. A sufficiently new
RT-11 definitely works. There are Unices that work on it, some from
DEC, some not (rumor has it that BSD 2.11 works, I haven't tried
that).
RSTS will NOT work unless you get my patches, which exist in fairly
finished form for V9.6 but aren't generally available.
As for the disks, I believe there are two flavors of the hard drive
controller, and the older of the two doesn't support RD53. I can't
remember whether it goes as high as RD52, and the docs I can find
aren't enough help...
