Actually I picked up two of them. They're HP graphics terminals with
dual tape drives. One of these has a HP-IB port in it. What's that for?
They're both marked that they have options 007 and 032. Anybody know what
those are? Anyboy have a pointer to a manual for them.
Also spotted a rack mount box that's marked HP 5478C. I looked through a
bunch of HP catalogs but couldn't find it in any of them. Does anyone know
what it is? The front of it is blank except for three LEDS marked
power(?), Trigger and DAC so I'm guessing that it's some kind of D/A unit
but it's darned big for that.

Let me know if you want to trade one of them away Joe, I've been looking for
a 264x terminal for some time!

What do you want to trade? :-) I can probably get rid of one of these.
One has a spotted screen but there's a third one out there that's apart and
I was already planning on grabbing it. Except for the one screen these
both look good and have a s&*(load of cards in them. Also got the keyboards
and they're both fine. However the capstans in the tape drives have all
melted (what else is new?)
Do you know what option 007 and 032 are? Do you have a manual for them? I
couldn't find anything on Al's site.

Two weeks ago while digging through a bunch of plastic bags of material to
be recycled at a local university dumpster I found the reference manual for
these things! I hope my luck with not being arrested and charged with theft
holds up a while longer.
Option 007 is the "Integrated Dual Cartridge Tape - Mini Data Station"
The option list in the manual only goes to option 030.
There are many built in accessories possible. They should be shown on a
sticker next to the main label above the power cord receptacle. They appear
all to be in the series 132xx.
I'll scan the manual as soon as I can get to it.

Yes, the catalog listed a bunch of 13xxx options. Things like Katakana,
Cryllic, microcode programmable, etc. But I didn't see anything about HP-IB
and I'm wondering if that might be what 032 is. I still have no idea why
you'd want HP-IB on a terminal.

That would be great. Can you E-mail me a copy after you do? I used to
have a small manual for the 2644 (IIRC) but I don't know what ever became

Unless I'm mis-remmebring something, the 2225C has a cnetronics parallel
interface. You meen the 2225A (HPIB). The 2225B is HPIL (and battery
powered), the 2225D is RS232. I've had all of them across my bench at
one time or another.
The 2225A is odd. The CPU in the thinkjets has a built-in HPIL port
(which is used in the normal way in a 2225B). The HPIB version has a
lttle non-isolated HPIB-HPIL converter that llinks to said HPIL port. The
version built into the Integral is really an HPIL version, with a 1LB3
HPIL chip to link it to the 68000 bus (again, with no isolating pulse
transformers.
The RS232 and Centronics models ignore the HPIL interface on the CPU
chip, and have interface circuits connected to the processor data lines.
The CPU firmware is therefore different.

I don't know about this particular list, but there are many noteworthy women in
our hobby.
Here's a reference point: there are several female subscribers to my
newsletter, more than I can count out of memory.
Just last week, a woman (Katherine Wasserman, Ph.D.) was the focus of the main
article! Katie collects vintage calculators, many of which are computers of
course; she even has a 1947 Swiss follow-up version of the Enigma machine.
She's got ** 300 ** pieces -- almost 400 if you count the replicas.
And what about Jeri Ellsworth? She's not active on this list, but she can
out-engineer Commodore stuff (and who knows what else) better than almost
anyone, whether they're boy, girl, or space alien.
Also, women are a huge segment of the vintage gaming hobby.

I remember writing some little hacks on the 3000 to send HP-GL to the

addressable as a device through a terminal escape sequence in much the

We hooked one up the other day and so far it seems to be working (it was

Steve Robertson has a working 3000 and a bunch of SW for it. IIRC he told
me that he had the SW distribution from HP and that it contained all their
3000 SW. After you bought what you wanted they gave you a license and an
access code for the parts that you bought. Steve's in the middle of a move
so I can't contact him right now but I'll try to remember to have him

Here's a little about your 2115 find.
They are by far, the most rare HP 1000 series processor.
Other than the one you mentioned, I'm only aware of 3 others
known to exist, and one of those is an unconfirmed rumor.
If you have any problems getting it running, I can help you out
with schematics and some spare parts.

Nice! Well it's nice and safe in warm storage now. I found a 2116B and a
2116C too, plus a matching paper tape reader.
Still no PSU for the 2115A, but I'm maybe only a third through the heap

I was also recently given a 2648, in excellent condition.
I have documentation for the 2649, and its fairly clear what sub-set of
features
are present on the 2648.
Limited IPL drivers already exist (but are not on the web site yet). A full
set of
IPL drivers for the graphics functions are being developed.
Its kinda odd how these terminals 'wake-up' with the text input directed to
the
graphical display rather than the alpha display layer. Makes looking at
directories
after cold-booting painful, so I had to write the basic terminal mode
control code
right off the bat.

Nice! Can you make a copy for me or scan them and post them somewhere?
I went back today and got the third 2648. It was pretty busted up but the
CRT in it looks real good. I think I found all the cards so I should have
plenty of spare parts too. One of the 2648s that I got early is complete
but the screen is real spotty. I'm planning on putting the CRT out of the
one that I got today in it. That should give me an extra in case Jay
seriously wants one.

Jay wants one, has for a long long time.
I have a 2645 and a 2649G, but both are DOA. Jay wanted these
when he was here for VCF East, but time never allowed me to load
them into his trailer (which didn't have room anyway).
I was going to trade these to him just a few weeks ago, but I tried to
get any sign of life out of either of them, so I dropped the ball. These
are not in good enough shape to be worth shipping whole.
Both have mold on their CRT's.
When I got the 2648 given to me (with a 7440 plotter), I was going to
send it along to Jay, but.....

That seems to be a common problem with our HP terminals, although
everything else from the same era is fine. (Couldn't tell you exact
model numbers yet as all of HPs numbers blur into one after a while! I'm
still organising our piles of HP surplus prior to making a list of what
there actually is)

It's not just the terminals. You find the same thing on HP 64000 LDSs and
9845 and 9835 calculators that use CRTs. I've never figured out why some do
it and some don't. I've bought stuff that's sat in un-air conditioned
storage with PLENTY of humidity here in Florida and it will be fine but
others that were stored under better conditions are full of spots. In fact,
the three 2648s that I just bought all came from the same place and were
stored under IDEAL conditions and one is almost completely covered in spots
but the others are perfect and have NO spots. I wonder if something
happened to some of them during manuacturering? I've seen a number of HP
voyageur series (HP-11C, 15C, etc) calculators that had never been
previously opened but had distinct spots of corrosion on the circuit board.
It appeared that someone had dripped sweat on them as they were being
assembled.
I guess I should start picking up any HP CRT devices that have good CRTs
and save them just for the CRTs.
