I did the degausser replacement way back as noted. I still have all
the files.
I did follow the design of the original HP version to a fair extent,
hence it uses an RC analog decay generator, relays, and such.
The microprocessor it used is obsolete, you might be able to find one,
or do a minor redesign to use a modern one, or just use one of those
tiny ESP all-in-one boards with some software tweaking.
Also, the relays called out have polarized coils. I had the polarity
swapped on the coils in one version of the pcb, I don't remember if I
corrected that. In any case, the relays aren't critical, pick whatever
you want to use that will fit.
Gmail won't let me send a zip. I hate facist mail systems. If you want
it, email me and I can set up a dropbox share or some such.
