With that work done, it may be practical to boot your HP over a serial port
at a reasonable
speed, but loading a large ABS file this way can take a very long time (as
things are).
I generally don't recommend the serial boot method due to its poor
performance.
Then again, I think its nothing to throw together a PIC and some I2C eeprom
and build
little paper tape reader and punch emulators, and I can burn copies of any
loader rom
you wish.
I found that serial booting the system to be the easiest way to get started. I don't
recall which one but, one of the loader ROMS will work with the "high speed
serial" card and read data off a serial link. There's no handshaking or error
correction but, with a short RS232 link, passing data is not a problem. The ABS data
format does provide checksum error detection so data errors will be detected.
On many occasions, I have loaded HPBASIC and other programs over a serial link with
absolutely no problem. The advantage to the serial link is that the only hardware required
is a RS232 serial cable. Admittedly, it is not as fast as a parallel link but, who cares
;-)
I had to write a PERL script to format the data before passing it to the 1000 but, that
was fairly trivial.

I don't recall any loader rom working with a 12531 HS TERM board. I could
well be wrong though, it's been WAY too long since I had my head firmly in
HP-world. You CAN do it with a 264x (terminal) loader rom and a BACI board -
as Bob S. said. If there is a loader rom that happens to work with the 12531
(ie, if the 12531 happens to have the same programmatic interface as say...
the paper tape board...) I'd like to know. I just don't have time to go test
it :)

Careful there... checksum (mod256) does NOT catch transposition of
bytes/words, missing all zero words/bytes, extra all zero words/bytes, and
identical bits swapped between words/bytes. There is a length field included
in the ABS format so that will catch missing or extra nulls. But it still
won't catch the other errors.

The paper tape loader ROM will actually 'work', if your 12531 interface
board happens to power-up in receive mode.
Or if you run a small program to write a control word to the 12531 prior
to running the loader ROM code (without pressing PRESET) you could
put the board into receive mode and run the loader.
But 12531 boards are slow, and not the most reliable. They often drop
characters when jumpered for higher baud rates.
But small program can indeed be loaded this way, at least sometimes!

Interesting.
This thread jostled a memory cell in my brain... I do remember one of my
machines having a loader room with a sticker on the top that said "12531". I
should locate it and dump the contents and see whats up there.

Special thanks to Brad for hosting these images. Brad will be getting a
chance to
become familiar with my Lotus Elise, most appropriate for 'heel and toe'

About the photos (not of the Lotus):
CIMG0600.JPG shows the keyboard and LED 'programmable key legend' display
unit.
CIMG0602.JPG shows the whole pile of gear.
CIMG0603.JPG shows the rear of the main chassis.
CIMG0606.JPG shows the EDAX hardware, packaged on quad SPC sized boards.
This is the ADC, preamps, analysis memory and display system, all driven
from a
Q-bus interface.
CIMG0607.JPG shows the DEC hardware, an 11/23 with MMU and FPP. There is
also a Sigma FDD controller, and a DILOG ST-506 disk controller.
CIMG0610.JPG shows the rear of the main chassis opened. At the top of the
chassis
we see the Shugart 8-inch FDD and a half-height HDD.
Intact or in parts, this thing needs a home. Lets make a deal!

The Apricot was an interesting machine -- MS-DOS compatible, but not

Circa 1991 I was messing around with a large (but narrow) Apricot tower

was a 386; presumably a Xen-something-or-other.

I get the impression that Apricot were a bit like ICL - the actual product

Maybe in the UK, but in the states there were relatively few models
offered. I remember there being only three models: the F1, Xi and a
mid-range model in an Xi style case but in beige instead of black.

drank enough so that I literally fell off my bar stool :-).
Then there was the "closing time" tradition of the owner at the store.
It would turn 5:00 PM and he would flip around the "open" sign in the

Sounds like it :) The best entertainment we had from both managers back then
was free gin at the pub down the road, this was dampened somewhat by the
fact we had to drive home afterwards so not much gin was drunk. Fun. Not.

That's pretty much how I got into computing too. Was a heck of a lot of fun at
the place I was at too - relaxed atmosphere and lots of interesting hardware
to futz around with.
It started going downhill toward the end though ('93 or so) as the PC
revolution had happened and 95% of the stuff coming in was just boring old
clones - there was no real fixing going on any more and it was all just about
board swapping :(
No idea when the place closed down, but it's long gone now...

Yep, the LED display above the keyboard is driven from a serial port
on the 11/23. Some simple logic drives a number of intelligent LED display
modules that put alphanumeric legends above the programmable function
keys.
If this thing gets parted out, I'm probably going to keep that bit, just
because
its absurdly cool.

You want to contact the Exec-PC BBS? Via dial-up? Is that still around? I

I think his name is Curt, but I'm not sure.

Does anyone on the list have the contact email
address for the sysop
of the ExecPC bbs? In trying to connect today all I get is "You are
user 49 in a queue of 49". This repeats until I disconnect.
You want to contact the Exec-PC BBS? Via dial-up? Is that still around?
I thought they converted to an ISP decades ago and pulled the plug on
the BBS.
The sysop at time was Bob Mahoney. I used to know him when I worked in
Shorewood. I think he sold the business.

Better than me, I'm the user 73 in a queue of 73 :oD

In that case, it would be interesting to see if the MS-DOS systems:
Hardware conference is still there. It was started at my suggestion and Bob
made me run it.
Just tried it. Putty times out and doesn't connect.

It's back on line Tom. Curt must have either noticed it or someone was
kind enough to notify him.
The MS-DOS conference is still there and has these message bases:
<A> Hardware Tom Peters
<B> Hot Topics Bob Mahoney
+<C> MS/PC/DR-DOS Keith Parkansky
<D> PC Life (commentary) Alan Frayer
<E> PC Review Forum Jake Moritz
<F> Public Domain Michael Barndt
It looks like you're still on the hook for Hardware. :)

New subject: Call for computer displays at MGC
Hi all, getting to be that time again and I'm calling for list members
that would like to show off their collections at this year's Midwest
Gaming Classic. The MGC is the largest electronic entertainment expo in
the Midwest (and one of the largest in the country), dedicated to
computers, consoles, video arcades and pinballs from past to present.
Just to clarify one list member's pre-concern in the past - this is not a
"kiddies" show. Though it is a family event, you will not have to deal
with "little kiddies" running around your eqiuipment. The bulk of the
2000+ attendees have been 25 and up.
Likewise, if you're looking to sell or get rid of equipment you no
longer want, this is the place to do it. We actually had a good ammount
of people specifically looking for vintage computer equipment last year.
The MGC is a two day show (June 9th and 10th) at the Olympia Resort and
Conference center (about 30 minutes outside of Milwaukee). Contact me for
more info or www.midwestgamingclassic.com.
I've worked hard the last 5 years building up the vintage computing
representation at the show, including displaying much of my own equipment
and archive material (I run the show museum). I'd love to see more list
members involved! Contact me directly for any queries, concerns, or
needs.

I get 'forbidden' with this one.

But 12531 boards are slow, and not the most reliable.
They often drop
characters when jumpered for higher baud rates.
I use a 12531 for downloading into my HP2116 and experienced the dropped
character problems when I first started. I found a simple solution however:
set the transmitting machine to send two stop bits (if one's transmitter
provides the option of course).
The problem with the 12531 is that - in addition to not being double-bufferred -
it doesn't indicate receipt of a character to the software until the end of the
first stop bit. With only one stop bit, the software then has only a fraction of
a bit time to pick up the character before it must restart the 12531 to receive
the next character, so it can sync on the already-begun start bit. If you send
two stop bits then the software has the entire period of the second stop bit to
play with.
I download multi-KByte streams into the 2116 at 19200 BPS without problem.
http://www.cs.ubc.ca/~hilpert/e/HP21xx/io12531BCD.html includes some notes on
jumpering for higher baud rates and a cable schematic.
