Dear all,
I have two VAXen that I'd like to resurrect simply for the sake of playing
around with The Real Thing[tm] running VMS. Note that I'm completely new
to VMS and DEC hardware -- hence the interest!
Box #1 is a VAX4000 model 400 with no working CPU (KA-675) and 2x 32Mb
RAM, an RF72

You could run the 3200 by netbooting it from a SIMH instance of VMS. If
the RD54 was formatted (and working!) then you could transfer VMS onto
the disk from the boot node.
G'day Rob, thanks for the quick reply.

The RF72 disk is a 1GB DSSI drive, and I think it's supported by the
base /400 machine. Once you have a working CPU, you can actually do
some testing on this disk drive with just the VAX console firmware,
because it's intelligent, and you

I have two KA-675s for this beast: Board #1 (originally installed) has
a failed B-cache (console reports SUBTEST_35_12,

Good to know -- many thanks, Peter! Most of the ones I tried were long
