Hello,
Do you by any chance have Vaxstation 4000 models or motherboards at hobbyist
prices?
Or anything like an inventory of your Qbus boards?
Other than that, I'm interested in a BA23, disk controllers (RQDX3 or SCSI),
DELQA/DEQNA.

The RD53s in both Microvax 2000s are dead. I'm reluctant to buy more 30+ year
old rotating media.

The old-school way to do this is to install inetd, ensure it gets started up,
and uncomment the line in its config-file (/etc/inetd.conf ?) for telnet.
Setting up an ftp chroot area is painful. If you're using cleartext passwords
(telnet) anyway, I'd set up rlogin/rsh, and use rcp.
Same story:

I have most of a Vaxbrick, but I'd sooner run Unix on it that VMS. But I know
of no open-source OS which supports the KA600.

The described behavior is what you'd get in X11 if the middle-button is "stuck
on" (autorepeating) after being pressed the first time, and you move the mouse.
Not sure if that helps, though.

What does one have to do (Linux, MacOS, *BSD) to write such an image to the CD

Ultrix UFS is 4.2SD plus some big fixes. It's definitely pre-4.3BSD. So 44BSD

I hit fsck errors anytime I mounted Ultrix FFS read-write with (very early

You may be better off if you can try with *BSD.
