[Coco] MPI problem or ...???

Had a little extra time so here's what I got from the PEEK:
I got the same results with and without the MPI plugged in. I think the power supply is the issue. Late last night I woke up and heard a 'humming' sound. After stunbling around for a few minutes, I unplugged the MPI and it went away.
Anybody know if there's a service manual for this unit? It's a 26-3024...
Again, thanks for all the help,

You don't want to print the value of $FF90 but the contents. The Basic
commands would be
10 FOR M=&HFF90 TO &HFF99
20 PRINT PEEK(M):NEXT
That will give you the contents of the GIME I/O region. The values with
and without an MPI need to match.
