Does anybody have an image of the VAXPAX (the VAX-11 diagnostic pack for
7xx machines, 8xxx, machines, and maybe a few others)?
I have one, but it's a fairly old version. It doesn't have any of the
82xx/83xx diagnostics and EVRLA doesn't know about RA70s.
Thanks,
Bob

You might want to look at what is used to run VAX diagnostics when the VAX780, and other
simulators are built using the current simh codebase. I'm not 100% sure that it is a
VAXPAX but it might be...

That's a good idea. After some poking around, there's a thing in there
called VAX_MINIMUM_DIAGS.dsk which has a bunch of the CPU diagnostics for
various machines. It looks like somebody put this together specifically for
simh, and it doesn't have tests for any devices other than CPUs.
It has newer versions that support the 82xx/83xx machines, which is
helpful but it doesn't have EVRLA (UDA50/MSCP diag) at all.
Hmm, since most of the VAX peripherals are shared with the PDP-11, I
imagine people tested them with the -11 diagnostics instead. That's fine
for the simulator, but for real hardware it's not always an option.

some latest official package that someone once either sent to me or pointed me at. I
didn't include other than the CPU diags for 2 reasons:
1) simh devices are NOT guaranteed to run the original diagnostics. Most often because
the diags had various timing loops or other assumptions about timing that don't make
sense in simulation,
2) The disk image is contained in the simh repo and the minimum set is a reasonably big
object to contain in a source code repo and adding extra stuff (device diags) that
can't be used has further impacts on the space used in the repo or an archive (tar or
zip) of the repo.

I have the RL02 for the 86x0, which contains a whole bunch of
diagnostics. I think newer versions of a bunch of them were done, that I
don't have. But maybe it is still more/newer than what you have at the
moment?

I have one, but it’s a fairly old version. It doesn’t have any of
the 82xx/83xx diagnostics and EVRLA doesn’t know about RA70s.

Thanks, Johnny - I copied it. There's a lot of weird stuff on here that I don't
recognize and which must be 8650 specific, but there are EXE files for a lot of the
diagnostics that are newer than the ones I have. I'll bot up my machine and try them
out tomorrow.
