What model HP 2100 do you have?
I have an HP 2114 with full docs, including the disk drive (if you look,
you should
see IOMEC on the drive). I am in the process of restoring my drive -- the
relay
power sequencer had blown out. I have made a temporary repair, and, after
cleaning
heads AND packs (first time I have ever done that), and making sure that
the head
unload mechanism didn't stick (it was sticky - had to degrease it), the
drive will
now spin up and loads the heads.
One thing you might want to pay attention to ASAP is the belt. On mine,
because the
drive had not been spun up for *years* the belt seems to have started
corroding the
aluminum drive motor spindle. Had to scrape and clean and burnish it.

I'm glad I got the first batch of docs for the 2100 stuff. But given that
the second batch of HP docs which I did not get went so fast, I have to
suspect there's some other 2100/21MX lurkers on the list :) One of these
I have a 2100 CPU + paper tape reader + disk drive. The latter takes
RK05-like packs, and is in very poor condition. The whole lot was rescued
just before it became scrap metal...
Alas I have no docs, and I think I'm going to need a schematic of the
board in the CPU box before I can do much. I have all the CPU boards (but
not the WCS option), 4 sets of core memory (missing one top connector)
and a lot of I/O boards.
It is very much a 'to be done one day' project. Yes I am glad I rescued
it, but until I get some more info it's going to be sitting in my machine
room...
