You might want to look ... current simh codebase.
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.
