The resistor goes on the battery plug or the unit will not power up. The computer was
suppose to have a battery bank to keep the DRAM from losing data when turned off, like the
original core used on earlier machines. The resistor detected the battery pack that one
rarely use.

Subject: Re: HP 1000 A class series boards
Hello Jesse,
I have this: http://everist.org/NobLog/20131112_HP_1000_minicomputer_teardown.htm
It's a stalled project, due to unfortunate circumstance. I was at the point of
preparing
to reassemble the machine (after cleaning) and start testing. Wanted to first test the
power
supply under dummy load, to check for bad caps etc. Could not find a schematic for this
model
of power supply online. Had contacted Jon Johnston, who ran the Australian HP Museum. He
said
he might have it, but was overseas (mountain climbing) at the time. He came back, but went
off
climbing again in the Himalayas before I contacted him again to remind him. That time, he
died
on the mountain.
This was doubly sad for me, since of my two best friends, now both dead, one had died
climbing
in the Himalayas (David Hume, Mt Macalu 1996), and the other had nearly killed himself and
me
by severe negligence while we were doing a short 30m climb here in Australia. So my HP
1000
restoration became something of an avoidance issue.
Since I joined cctalk and vintHP, I've been meaning to restart this project with
assistance here.
But too busy so far with other things.
At the moment I'm not sure if my machine is an 'A-series' or not. How do I
tell?
It's a 2113E, apparently quite a late model. I've had it and related hardware
(minus disk drives)
since the early 2000's. It was a junkyard find. All in perfect condition except one of
the two
tape drives has a little 'forklift damage' to the front. I rescued it all from
being landfilled.
