Howdy all!
I'm the new owner if one of the coolest "Calculators" HP ever made.
Everything generally works but I would need a new capstan (rubber is now
sticky) to use with the tape cartridge.
I am running into a hard time tracking down information on using it though,
so if anyone can help fill in some gaps, that would be great!
I'm looking for:
- A manual for HPL, the language used to calculate. Things like for loops
don't seem to work, but 'dsp' 'gto' and variable assignment do.
- Manuals for any and all of the cartridges, and how to use them
- Ideas on replacing the capstan
- Ideas on refurbing the tapes (there's a rubber band equivalent to drive
the tape on both sides, these have lost their stretch)
- Specs for the I/O, as I would love to make custom I/O for it.
I would also love to be able to create new cartridges, but I'm not willing
to sacrifice any of my existing cartridges to Reverse Engineer them.
I have the Plotter / GPIO Cartridge, the Mateix cartridge and the Strings
Advanced Programming.
Trying to track down an Assembly cartridge or any others.
Thanks! Any info is appreciated!

I sort of doubt any of these boards were factory supplied this way, but the date codes on the ram in question are consistent with most other ics . the other banks contain chips that are months older, or newer.
64-256KB SYSTEM BOARD
18 TI gold capped 4164-20 chips in banks 0 and 1.
Mix of Fujitsu, TI, NEC chips in banks 2 and 3.
There are a half dozen numeric codes present on the board. I don't know what any signify.
Time to dispose of some more of my stuff so it doesn't
end up in the trash when my widow has to clear the house.
Any interest in BA356-SBs? All with disks in them. And
I have a decent stack of used RZs in caddies. I even still
have 11 RZ28's still in the static bags. Would have to be
someone close enough to pick them up here in the Poconos but
I have seen a lot of postings from people in Eastern PA and
north and middle NJ.
Is it worth my taking the time to count up exactly what I
have or would no one be interested in making an offer.
They will not be going on eBay.
Just for information, I have used these with PDP-11's
with 3rd party SCSI modules, PC's with SCSI Cards and
Ersatz-11 and even a Tandy Color Computer with a TC^3
SCSI card and NitrOS9.

I'm having bit of fun with my various CP/M systems but I ran into
what I see as an interesting problem. I got Turbo Pascal on two
systems. A TRS-80 model 4P running Montezuma Micro CP/M and a TRS-80
Model II running Pickles & Trout CP/M. I tried to compile the version
of Kermit written for CP/M using Turbo Pascal. On both systems it
runs out of memory and crashes in the same place. Surely the developers
would have noticed this. Anybody here have any experience with this?

Has anyone communicated with or know a way to communicate with Joe Rigdon
out of Florida? Most here should know him as an old-school ClassicCmp
veteran.
If anyone has any information at all on the whereabouts of Joe Rigdon, and
for that matter John Lawson, please either reply here or to me privately as
appropriate.
Thank you.

I have a Dell Vostro.
When I boot, the screen briefly flashes and then remains dark.
I have another one on which the screen would stay lit for a minute or
two, then go black. If I closed the lid and opened it, it would stay
lit for a few more minutes, then go black again. I corrected that by
replacing the backlight power supply.
In this one, is the problem more likely a defective power supply for
the backlight, or a defective backlight, or something else?
Thanks,
Van Snyder
The DEC VT340 has a slot in the back of the terminal to insert a ROM
cartridge. I can't find any description of what this DEC labeled ROM
cartridge would do for you. I've seen them with V1.1 and V2.1 markings,
does anyone remember what additional capabilities these ROM cartridge
provide?
