Some questions if you don't mind ;-))
Not at all!
- Could you please give some instructions how you managed to install V1.0?
Yes, I suppose this should be documented, as I have been unable to find any
installation documentation scans for Ultrix-32m 1.x. The installation
process needs the disk to be rq0 and have two floppies, rq1 and rq2.
32m-bin-1.0/01 needs to be attached as the first floppy and 32m-1.0-bin/02
needs to be attached to the second floppy. I chose to use the RD52 for
installation as 1.0 doesn't understand any of the larger RD-series disks.
/etc/disktab does have entries for the RA80 and RA81 but my recollection is
that trying to install to those disks didn't actually work.
- What kind of error messages did you get when you
wanted to install V1.2?
It looks like there is an issue with the bootloader - the self-tests go
into an infinite loop. I have yet to try moving the bootloader from 1.0 to
the 1.2 system, but I believe this should work.
- What microvax1 simulator did you use: the OpenSiḿh
one or that from Simh
(Mark Pizzolato)?
I am using OpenSIMH but I don't believe there are any significant
differences between the two branches that would affect this system.
- What is in your microvax1.ini file?
Here is an INI file for installing 1.0; you don't have to use the QVSS but
I enjoy the experience.
