Nice job. I have downloaded your images and they look fine.

Your console tape has microcode version 57. The one on my FTP site is not
pristine, but has microcode version 58, so it should have one fewer ucode bug,
or at least so one would hope. :-) Of course it's nice to have both.

The diag supervisor and microdiag should be quite helpful if anyone has a 730
that's feeling a bit sick. Also the diag supervisor is not specific to the 730,
it originates from the 780 and runs on all large VAXen. I will use it as part
of the validation process for the new VAX CPU I'm building. (Even if we do
some day manage to pry AXE out of HP with the help of some KGB death squad, the
VAX should still pass the basic diag first before attempting a random test like
AXE.)

I'm still waiting for the TU58s that I've recently bought on eBay that have the
rest of the diags. Brad, I'll talk to you in private about them.

Those who prefer the original UNIX to Linux can save the effort and use the
standard arff(8) console media manipulation utility that comes standard with all
VAX UNIX distributions. You don't need to actually run UNIX on the large VAX
in order to use it, it'll happily run on a MicroVAX running 4.3BSD-Quasijarus
and operate on an image file.
