..but I have an ex - 15Mhz M8190 with FPU here, put a newer J11 (-008)
on it, changed the xtal und use it with PMI memory as an 11/83.
Tested it with xxdp,rt11 and 2.11BSD over a long time, no problems at all.

Nope, it's only 15MHz ... and the MSV11-Q
memory isn't PMI, so it's an
11/73.
A discussion as to whether the addition of second board can change a first
board from an A to a B would I suspect be non-productive, so I will pass over
that point. :-)
One thing that I am curious about is the 15MHz aspect: what did DEC (if you
recall) call a 15MHz M8190 paired with PMI memory? (Recalling our prior
discussion, which I am too lazy to look up and give a pointer to, about how
all the M8190's can apparently do PMI.) Did they (or would they) have
regarded that as an 11/83, or did only the 18MHz version get the 11/83
moniker? (Too many different configurations - 15/18, PMI/non-PMI - and not
enough names!)
