So, I'm mostly recovered from the move to UT and I've gotten back to
working on the HPs I acquired.
http://rikers.org/gallery/hardware
I've fixed the visible issues with the HP-2116A and powered it up slowly
with a variac with a minium of cards installed.
Fans spin up ok, I get a couple of the power circuits live, but fuse F8
blows and the rest of the power circuits do no come up. No lights on the
front panel etc.
I'm reading through the HP-2116B vol2 manual on bitsavers (Thanx Al!):
http://bitsavers.org/pdf/hp/2116/02116-9153_2116B_Vol2_Oct70.pdf
But there are some differences in the power supply between the 2116A and
2116B. I don't have an A1 card for example, and the core memory is
completely different.
I'm kinda beating my head against the wall on this one. Still hoping Bob
or someone else will dig up a Volume 2 manual for the 2116A sometime
soon. =/
In the mean time, I've repaired and powered up the HP-2108A system.
Things seem to checkout ok. Now anyone want to suggest a light chaser
program to key in for kicks? I don't have any manuals specific to the
HP-2108A here, but I suppose I should try some of the memory diagnostics
routines from the 2100 or 2116 to check things out.
The basics seem to work. I can store/recall values from registers and
memory. I've not tried all memory locations or anything yet.
I'm hanging out on #classicmp on irc.freenode.net as usual. I was hoping
Jay would be around sometime or others that might suggest what to do
next. ;-)
My paper tape reader seems to spin up ok now, but I've not tried to talk
to it in software yet. Also I don't have real tape images for things
like the basic1 environment:
http://oscar.taurus.com/~jeff/2100/hpbasic/basic1.abs
I've got my hacked simh that has ANSI text register displays to test out
routines on. That's been very useful. ;-)
Any suggestions on getting pc based paper tape images over to real HP
hardware?
I do have a paper tape punch, but no docs on it. Also I don't currently
have any blank media.
Thanx!

Ok, where did you find a variac
that supports that kinda amp load? :)

I'm guessing fuse F8 blowing has something to do with that ;)
I haven't a
clue, the power system in 2116 is likely pretty different I think from what
I'm used to. Now, if someone wants to donate an HP2116 to me, I'll get all
familiar with it. Promise ;)

And you don't need anything
specific to the 2108. Look in the CE handbook.
Common data I think is the section (going from memory). There are quite a
few short ditty's there that you can enter via the front panel and use to
test the system for basic function before heading to diagnostics that
require certain things to work. Most of the ditty's there are expressly
designed to test the functions that are required to load diagnostics, so
there is little or no guessing. Make sure you run the diagnostics (from
media) in the order put forth. Once you get past the ditty's in the CE book,
let me know what media you have to load diags on. I'll get you a diagnostic
library and you can learn the joys of the Diagnostic Configurator :) Once
that's up, you can test most peripherals and I/O interfaces quite
thoroughly.

Since you expressly limited it to pc based paper tape images... there is
a
solution. Look at the 264X terminal loader rom. It speaks a trivial protocol
to get binary images into the cpu. You could write a very simple script to
download the binary files on the pc to the memory of the 2108.
I do have a paper tape punch, but no docs on it. Also
I don't currently
have any blank media.
I could send you a little bit of blank paper tape if you need
it.

CE handbook on line someplace? This one?

Grabbing. Thanx.
Sounds like a great idea. Is the source for this ROM around someplace?
Also, what does an ASR-33 do to load tapes? or perhaps it's tape drive
cannot be used for diags/booting? (I don't have an ASR-33, I just
figured it might be easy to emulate)
Yes please! My punch is not an HP, so I doubt I'll find docs. It's a

Heh. borrowed one from TI, and then forgot I had, and the packers packed
it up. Now I have a brick I probably need to mail back to texas. =/

Well, that's the issue. I don't have any media working yet. My paper
tape reader might work. I've not tried reading from it yet.

CCC changed their name to Friden in the early 1960s so look for Friden
docs. FWIW CCC used to be National Postal Meter and they made M1 carbines
during WW II. In early 1945 they saw that the end of the war was near and
they wanted a more commercail name so they changed their name to CCC.
