Sirs:
Adrian Graham at the Online Computer Museum recommended I contact your group
to try to locate a disk for my Compaq Portable 3. I realize it falls into
the dinosaur category but someone gave it to me and the challenge of getting
it operational was too much to bear.
When it finishes counting all 640K of memory, it reminds me to use a setup
disk or hit "F1". When I do that, it mentions there is a non-system or bad
disk. Then the message keeps repeating when trying various type of DOS disks
I have. I have the feeling Compaq uses something like DOS but I have none of
those OS disks.
Any help would be appreciated.
Thank you,
Bob Schoppe
What kind of an HP 1000 uses those? Must be an A-series, the M/E/F machines
certainly don't... The 9000/800 series certainly do, can't speak for earlier
systems..

This is what Wayne Lafitte (the guy selling the TI CC-40 units) told me
about the product. He was a marketing manager at TI and he was
responsible for the CC-40.
"This product was manufactured out of Lubbock, Texas in 1982-1983
timeframe. There were only a few thousand 6K CC40s made and only a few
hundred 18K CC40s made. The wafertape (stringy floppy) met it's end early
on because of compatibility issues between units. These didn't make it
past the prototype stage (very few made). Most of the cartridges were
developed from the software libraries created for the TI59 and TI58 hand
held programmable calculators. The 18K CC40s were made to support the
industrial markets and VARs, but really didn't take off. If you remember,
the IBM PCs came out in 1983, the Hewlett Packard hand held programmable
calculators, and Texas Instruments fiasco with the TI99/4 home computer
pretty much killed this product. By the way, a new hand held calculator
(the TI88) was being prototyped at the same time as the CC40. The TI88 was
a very neat little replacement for the TI59 but the product was cancelled
before it was put in production because the CC40 was believed to be
better. In my opinion, that was a mistake.
"The CC40 products were mainly sold through TI employee sales stores and
never really reached the consumer market. There were a few VAR customers."

Well the RD52 in my 11/83 died, only the second failure for this box
in over 12 years. Tried to use the UC07 board (out of a mVax) to instal
a SCSI drive but can't get the 11/83 to recognize it, let alone format.
Anyone had success in using this board with the PDP11? I've set the
address to 172154 as the M7555 is still onboard to allow the rx33 as
the boot device. Will the DEC diags format the SCSI (i expect not)?
Thanks ........ nick o

Although I don't personally have one, I believe you should be able to use a dos disk. The only caveat being I am pretty sure only has a 720k drive. If you can find a 720k disk, format it and put your favorite dos's system files on it and then try it. It may sound funny, but I just recently ran into the exact same problem with a GRiDcase 3. Works like a charm now :-)

Replacing an RD52 is not such a big problem. Just take a ST251 drive or
another MFM drive from an old PC and format it with your M7555 using XXDP
utility ZRQCH0.

Greetings and Happy Daytona 500 to all,
Yesterday, at the CU auction, I picked up a 'HP Entria' model
number "C3232A"...
>From what I can find on the web this is a color Xterminal. On the
bottom it says "color - Maximum Resolution 1280x1024"... BNC (10base2),
RJ45 (10baseT), serial, parallel, mouse, keyboard, HD15 video connector.
Does anyone have a power supply (20VAC, 2Amp, 4 pin rectangular
plug)? Any information? Does this require a code load from the
host, or is the code resident? Is the HD15 connector SVGA?
Thanks,
clint
PS I'll accept offers if someone wants to buy it also... It's pretty
small and light so shipping shouldn't be outrageous...

Hi,
I've got a VT200 here that's having display problems - vertically everything
seems fine but the display is garbled horizontally. Any ideas what to check
for? Might be a common fault with these things??
cheers

My error, it's TV RF out.

To my knowledge just RF out.

Jeff, this would be very helpful. I believe the TC2048 is a 48K Spectrum is
a different package.

Well . . . I think the owner would prefer not to but I'll pass along your
suggestions.

Sure, that's how my ZX81 is set up.

Thanks, that's very helpful.

As stated above it's a 48K Speccy in sheep's clothing, so it *is* color.

Tony, you are correct in that the ZX81 and TS1000 pcb had various traces
labeled "US," "UK," "FR," etc. but I doubt the TC2048 does (since the
Spectrum didn't).
No ROM change is required.

Hmm, probably not acceptable to the owner. BTW many ZX81s sold in the US
(including the outrageously expensive kits offered by Zebra) shipped with UHF
RF modulators.

Probably the best solution. See below.

Cameron, you might be confusing the TC2068 and the TS2068.

Think about that question for a moment and ask yourself if you *really* want

Jeff, great idea! Thanks!

And thanks to you too, Cameron. By pure coincidence I'm spending a week in
Germany next month, attending the annual meeting of ZX-TEAM, the last active
ZX81 user group. I could bring back a small color TV for my friend to use
with the TC2048.
