I've never seen a board with the ability to disable parity...

It's a clearpoint board.   Technically it's just disabling the parity
circuitry CSR.

The "***EXEC PARITY ERROR STOP***" message is when you get a parity
error in the memory where the kernel resides.
RSX can deal with memory errors in other parts of the memory, by just
making that memory unavailable for programs to use. But it cannot do
this with the parts that the kernel use, so then it panics instead.


Ahh.   Damn.   I'd be okay if the only other memory board I had spare
wasn't PMI.

PMI? As the the PMI memory boards for the 11/83?
Did you know that those memory boards work just fine as normal Qbus memory boards? :-)

There's that 16K board...I could adjust the memory offsets.

Ugh! 16K is not much...

First bugcheck is essentially an illegal instruction in kernel mode.
(Error code=110 is illegal instruction, while facility=300 means the
executive.)

Ahh.

No idea why you got that one, though, unless it was a fallout of bad memory...
