I've fixed the visible issues with the
HP-2116A and powered it up slowly
with a variac with a minium of cards installed.
Ok, where did you find a variac that supports that kinda amp load? :)
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. =/
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 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 ;)
I'll get right on that. =)
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.
And you don't need anything specific to the 2108. Look in the CE
handbook.
CE handbook on line someplace? This one?

Grabbing. Thanx.
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.
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.
Any
suggestions on getting pc based paper tape images over to real HP
hardware?
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.
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)
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.
Yes please! My punch is not an HP, so I doubt I'll find docs. It's a
"Motorized Tape Punch - Model 2 - Commercial Controls Corporation -
Rochester 2, New York"
