I just got a PCjr, with a Quadram Floppy drive extension, and a parallel
sidecar... It worked fine for a couple days, and then I booted it up and
it checked up to 128k, and then reported Error A... does anyone have an
error code list for the PCjr?

Yes, that's it...
The system is working again. I'm going to run through it again and see if I
can find any bad memory chips that I'll have to replace...
Thanks a bunch!

I've got a ROM BIOS source listing...
Assuming I'm reading it right, the 'customer' error codes are the first 2
characters (high byte) of the full 'manufacturing' error codes. Code 0A
is a planar bd (motherboard) RAM problem
