The photo does not inform me as to what is wrong.This is happening...
One is not meant to run EXE or COM files on those IBM diagnostics floppies. One boots from the floppy, and does things via the menu.What I'm not sure of is when I run diags.com, I end up with a cursor and the disk spinning forever...

ERROR - SYSTEM UNIT 902
The diagnostic floppy is used together with the diagnostic maps at [here].Can't seem to find info on the 902 ...
( It sounds like you have an IBM Printer Adapter in your 5150. )
So if you remove that, the 902 error goes ?This one has a Quadram Quadboard with a parallel port.
Got rid of the first one, apparently I had an HD disk installed..
Know that IBM expect:This one has a Quadram Quadboard with a parallel port.
