Here's what came in my last acquisition of HP gear that I started to unpack
today....
(2) HP 2113E cpu's in impeccably mint condition. They look refurbed (no dust
at all). The have been tested and run diags perfectly. Each one has 512KW,
DCPC, M.E.M., Mem Protect, and 2102E memory controllers
One has loader roms: 264x terminal, 7970 magtape {YES!}, 79xx Disc, CS80
disc
The other has loader roms: 264x terminal, 7970 magtape, 79xx Disc, and
7905/06/20/25 disc
Here's the cards between the two...
(2) 13037 disc subsystem interfaces
(2) TBG
(2) BACI 12966A
(2) Line Printer 26099A
(2) BUS I/O
(5) GRD TRU IN/OUT
and..... a 5060-6282 prototyping board!
Other items in the racks...
13037D disc subsystem controller (this one is MINT!)
13037B disc subsystem controller
12979B I/O expansion chassis & PS
(2) 7906D disc drives (both appear to be in extremely clean condition)
(2) standard cream colored HP racks
Much fun!

New subject: Ohio Scientific's Rescued...need help/info!
Last night I rescued two Ohio Scientific systems:
A challenger C1P and
A Challenger II (which was a MUCH bigger box, and had a matching big,
heavy dual 8" floppy cabinet).
The haul also included an ADM-3A terminal (always wanted one of
these), and a dual 5 1/4" floppy cabinet (don't know which system
this goes to).
I got no documentation, no software or anything
(these were all picked up from a curb-side garbage pile!!)!
I've always admired the ohio scientific systems...and almost bought a
C1P back in the late 70's (it was a toss up between a C1P and a
trs-80).
Any pointers to documentation, software, specifications, etc??
I've read the stuff on a careful process to power-up an altair...does
this apply to these systems too (I don't have much in the way of
electronic test equipment or power supplies).
thanks much!
Man...I hate to think of these classic's going landfill...... gotta
save 'em all!

Last night I rescued two Ohio Scientific systems:
Congrats!
A challenger C1P and
Plastic or metal case?
A Challenger II (which was a MUCH bigger box, and had
a matching big,
heavy dual 8" floppy cabinet).
Blue/black or tan/brown?
The haul also included an ADM-3A terminal (always
wanted one of
these), and a dual 5 1/4" floppy cabinet (don't know which system
this goes to).
I would like to see a picture of this. It's probably not OSI.
I got no documentation, no software or anything
(these were all picked up from a curb-side garbage pile!!)!
Lucky, lucky lucky! Where?
Any pointers to documentation, software,
specifications, etc??
I have lot's of docs, etc. for OSI. OSI is the principle focus
of my collection.
I've read the stuff on a careful process to
power-up an altair...does
this apply to these systems too (I don't have much in the way of
electronic test equipment or power supplies).
OSI uses regulated supplies. Generally, they either work or they don't.
I've never had one zap anything... but anyway, the 5 volt supply in the
C1P is easily disconnected from the main (and only) board. Put a dummy
load on it and check. 4.7 to 5.3 is cool.
The Chal. II will probably have a PowerOne supply (again, very reliable
in my experiance). Pull all of the cards from the "fatherboard" (you'll
need to anyway, just to reestablish contact) (the order of the boards on
the bus does not matter) and put dummy loads and check voltages on the
following pins (counting 1 to 48, top to bottom):
23 - +12
24 - -9
25 - +5
26 - +5
27 - gnd
28 - gnd
Man...I hate to think of these classic's going
landfill...... gotta
save 'em all!
Contrats again!

I'd really like to see (or at least get a more detailed description of)
this dual 5 1/4" cabinet. If it has an OSI tag on it, what it says,
what color is it, etc.
Any pointers to documentation, software,
specifications, etc??
I have lot's of docs, etc. for OSI. OSI is the principle
focus
of my collection. The C1P has a ribbon cable coming out of the side of
the top, that
looks like it's intended to hook into some other board..any idea what
this might be for?
(it comes out of the right side of the keyboard).
It could really be just about anything! C1Ps are almost always hacked.
I don't quite understand your description of where it comes out. If it
is a wide cable, around 30 pins (memory fails at the moment and I can't
go digging for the docs right now, I would wake up the kids and get in
trouble) and it comes out of the back of the unit, then it's probably a
floppy cable to go to the 5 1/4" drives. If it is 12 or so pins and
comes out next to the keyboard, then it might well be a cable to go to
the optional num pad that OSI made.
