Exactly! I've rescued two of the past business computers from my company
before being dumpstered. First, in 1991, was a 1982-vintage Hewlett Packard
HP250/30 of which I only knew a tiny bit but have learned a bunch since.
This was by simply tearing it apart, studying it, cleaning out much dust
and junk as part of my restoration, reassembling and firing it up. No
documentation whatsoever except for a small Command Reference Guide found
in a desk drawer. I have a stack of hand-drawn schematics of the CPU board
and parts of other boards plus part of the address map, etc. just from
spending time at it.
Next in May, 1997 I got a 1987-vintage IBM 9370 which is still a work in
progress as we've been very busy with buying and moving into a new house.
At least I have all the documents except for the OS manuals which a third
party software support vendor kept. From those docs and from tinkering with
the hardware I have learned a respectable amount but have more to go yet.
Would like to find IBM CE docs on this machine and the HP.

Well, I am looking for a decent DEC PDP-series machine though I don't know
(yet!) a lot about them. I've programmed a couple of DEC machines in
assembler and Pascal during various studies at the local college. That is
somewhat important to be a little prepared but it doesn't amount to much
because I have had virtually no hands-on hardware fun yet. Now I want to
get one to preserve and actually learn more upon. I've not asked here on
the list yet for one that's available, but someday within the next year or
so I will ask if one doesn't show up nearby to me beforehand.
My curiosity at wanting to learn how things work, such as what I've
reported above, has served me very well. I would not have the engineering
job such as I have now nor the activity I have in the antique radio
collecting hobby if I was not so interested. Life would be a whole heap
more boring IMO.
