Somehow these were sitting in my basement rafters for years.
The tape seems ok on the big reels but I believe one of the small
reels was gummy. Several write rings on the pile too.
I'd rather not have to box these up TBQH but I will if someone
really wants them.

some weeks ago I've purchased a System 37 in ebay. This unit was ebay in
the year 2020 and the owner was made this video too:
When I power up the displays shows a 1. Sometimes if I stop and start fast
the display shows a 2, but in all the cases all the leds stills lighted.
The voltages on the power supply are OK, and in general I the unit have a
good look, I don't see corrosion or leakages from capacitors.
Looking the SPU training PDF of Bitsavers/HPMuseum , looks that maybe is
related with a ROM or the WCS.
Somebody have more info about this error, or know if is possible get some
schematics / service manual?
Thanks a lot
Is there a simh for the otrona attache? I have some.disk images created
with Dunfield's utility..if not I will try to read them by using the Zorba
portable, which is pretty good with varied formats.
I found a vintage rackable linear PSU at a sale over the weekend, appears
to be late '70s vintage going by date codes on some of the high-power
Front panel is plain black with just a power switch and telltale lamp.
Back has a ratings sticker which says "PPI 1247-000-91 ADDS".
Outputs are +24V at 3A, +12V at 2A, +5V at 30A, -12V at 4A.
Ring a bell with anyone? I'm familiar with ADDS in a terminal context, of
course, but this lump is obviously for something larger - perhaps a
"washing machine size" fixed/removable drive unit or similar, but I'm
surprised there's not obvious branding on it if so.
