I'm very interested in getting another HP 1000 machine.
The 2113 I have now is not as stable as I need it to be. Lets make a deal!
As I mentioned in my earlier post, I have a one-of-a-kind instrument based
on a HP 2113 CPU, and I need to keep this instrument working.
The time base generator boards are very simple, that accept a 3-bit value
and will set their I/O flag bit after the selected time period, which can be
10 sec, 1 sec, 0.1 sec, 0.01 sec, etc.
Usually the TBG board is installed in slot 10.
You also have a HS Terminal board. Excellent, these are slightly rare. This
is a serial port board that will run up to a maximm of 2400 baud, and it is
compatible with HP Basic. Normally these use a current loop interface, but
a simple modification to the I/O cable (inside the hood that connects to the
PCB) will give you RS-232 I/O. I can supply all the info you need for this.
(I just build such a cable for Jay West, I can make you one if you don't already
have such a cable to modify)
Oh yes, your going to have to use a terminal with 2400 baud, 7 data bits, space
parity, and 2 stop bits. Hyperterminal works just fine for this.
Install the HS Terminal board into slot 11 for use with HP Basic.
The microcircuit interface boards are very valuable. You will want to use one
of these as your reader-emulator interface. I'll need to know if they are '+
True'
or 'GND true' boards, the differance being true or inverting cable drivers.
As for the 55613 GMR-1 board, I have no idea on this item. I'm stumped, and
thats not too easy. Its not listed in my HP interface manuals.
The INTF 1337, I suspect that this is a 13037, the common MAC disk interface
controller. This is not a disk controller itself, but an interface to a
rack-mounted
disk controller box. In my opinion, its useless, unless you have a working MAC
disk and controller. They are very common boards.
You have the high-speed memory (12747H), which usually goes with the 'E' series
high speed memory controller, a 2102E. But as long as your passing the
microcode
memory tests, I'd leave well enough alone.
(to test a HP 1000 CPU, set the A register to 100000 octal, set the P register
to 000000
and open the front panel. Switch the Lock/Operate switch to Lock, then press
Instruction
Step. The CPU will run full CPU diagnostic microcode, and test all installed
memory.
The S register will increment for every 32K word page of memory tested. This
test will
run forever, until the lock operate switch is moved back to the operate
position).
My 2113E died (again) last night, and will no longer pass the CPU part of the
diagnostics, indicated by the overflow light comming on, and no memory test
incrementing in the S reg.
So I'm very very eager to make a deal!
The Natel 2101 R/D converter also stumps me, is this a third party I/O board?
Now then, a tape reader emulator...
My emulator uses a PIC 16C65A to talk to the microcircuit interface board, and a
bank of EPROMs that hold images of the paper tapes. I also have modes to read
from a generic paper tape reader, or from an application running on a PC (PC
application not working yet).
If all you need is to boot HP Basic, I can build you a simple version of the
emulator, or
simply send you schematics and pre-programmed PIC and EPROM chips, at your
preferance.
My reccomendation is that you snag the rack mounted systems, I'll contribute
some cash, and whatever reader-emulator support you desire. What I need is a
working 2113 E processor, and I'd love to have a set of floppy drives as well.
If these systems have the HP 7970E tape drive, thats a sturdy, reliable tape
drive that is not too hard to get running with simple assembly language
programs. I have one, and would reccomend it to any HP collector. Nothing says
vintage like spinning mag tape and blinking lights!
The only difficult part of this I see, is getting a 2113 CPU from where ever it
is, to my location in centeral Massachusettes. But my need is great, and I'm
willing to cover any
shipping costs.
Lastly, if you have any interest in assembly language programming on your HP
machine, I can email you a DOS executable version of the original HP assembler.
You can look at the listing output and toggle small programs from the assembler
directly into memory, and get your lights blinking. Also, I have a small
program called Octapus-C, its a small monitor-like program that allows you to
assemble small programs line-by-line from a terminal. Its crude, but effective.
Both HP Basic and Octapus-C will easily fit into a single EPROM chip, and you
can select which image is loaded by a simple switch.
So once again, lets make a deal Steve, you may have made my Christmas here!
After reading your post, I was tinkering with my machine last night, and it will
no longer pass the power-up self tests.
Oh yes, if you look at the pictures from VCF East, you will see my
reader-emulator being used to boot the HP 2114A I displayed there.
