Allison, I have a 96tpi MPI with Part number 77686000, so it is
apparently not that. I also have a 100tpi MPI, bit it is installed and
inaccessible now.

is this 35, 40 or "other" cylinders?
is it 48tpi, 96 or maybe 100 tpi?
It gets cranky from tracks 9-14 inward (even a Format) and it makes me
wonder what it is or is it just flakey? Appearances suggest flakey but I'm
making sure it's not an oddball MPI 100tpi.
I'm sure that you have checked that the head assembly slides freely on
the guide rods.
FYI: it's a NS* Advantage and it runs fine off a
generic HH5.25/48tpi
floppy.
Certainly points at the drive.
Anyone have a NS* CP/M OS manual for it. It has CP/M
and it's apparently
a NS* version for the Advantage and slightly strange compared to others I've
seen?
What is different about it?
