Yeah.
Did you know that those memory boards work just fine as normal Qbus
memory boards? :-)
THAT I did not know! Looks like I have a spare.
Indeed. Those memories are funny. If you put them in an 11/83, they either act as Qbus memory or PMI memory, depending on if you place them before or after the CPU. And that makes a speed difference...
Cool.
Of course, for all other type of systems, you'll have to place them after the CPU.
Yeah. ;)
There's that 16K board...I could adjust the memory offsets.
Ugh! 16K is not much...
Nope...but MAYBE just enough to fit the lower bits of the executive?
Maybe. But I think that PMI memory is a better option. :-)
Yup. ;)

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?
Yup!
Nice.

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...
Could very be fallout of bad memory.

512Kbytes is 256Kword. :-)
Ahh.
But it's not clear that the address are in Kwords...
It's a 1M board...so it's either at the very upper end of memory or in
the middle.
Unfortunately it is before the halfway point, so you'd have to disable more than half the memory...
(If it isn't close to the total end...)

Do I have a bad memory board? It's far, far too late to return this one...
Is that some output already at power on before anything is booted? That would mean some selftest failed.
Nope. The only output I get at power on is 173000 (halt switch in).
I commented earlier on the other error you saw, which definitely is a case of parity error...
Yeah.
