This reminds me that last year when MARCH (Mid-Atlantic Retro
Computing Hobbyists) restored a PDP-8 that had come from a high school
computing club, they dumped the magnetic core memory and found three
programs:
1. A program to dump memory contents to paper tape
2. Some common utilities for debug
ve the observed behavior. It's
possible something else was happening then too, so I'll retest.

I noticed you changed the destination to cctech instead of cctalk,
James. I'll try to do that in the future for on-topic-only
discussions, as I suspect that's the custom here.

A lot of good information here, and I have a music store near me that
I might be able to find a suitable felt or wool pad from. If not
there, then perhaps at Home Depot or online.
Was it uncommon to use floppy disks formatted in other 8" drives in a
machine like this? When someone (very charitably
Are there any good alternative solutions I can do to replace it? I'm
sure I don't want the plastic touching the disk media.

I have two intermittently functional 8" floppy drives that I debugged
to the best of my ability, and as far as I've been able to tell their
problems must be limited to the circuitry that deals with the actual
magnetic interface with the disk. The intercommunication seems normal
and the head load so
