I may have a chance to get a NCR Model 1203-6000 (it's about one step
>from abandonment). It appears to work and run both CP/M-80 and MS-DOS.
On the serial number sticker it lists its manufacturer as NCR GmbH- am I
to assume this may mean it is of German origin?
My questions are, has anybody heard of this machine? Does anyone have any
info on it? Is it even a classic?
Thanks,

A Morrow Pivot. Portable, battery-operated MS-DOS machine; I'm not
sure how IBM-compatible it is. Made by Vadem in Milpitas, OEMd by
Morrow as the Pivot, Zenith as something (think they sold a bunch to
the IRS), Osborne as the Osborne 3.
Keep your eyes open, there are others out there. I've seen one at
Halted in Santa Clara but as usual for Halted they were asking a
bogus price for it, something like $100.

I must admit, I haven't booted mine recently. It is just about visible
under the pile of junk in that part of my computer room...
I can, however, easily get at the manuals. The service manual is not
much use, I'm afraid, but I can look up the diagnostic codes for you. I
shall try and do this this evening, and post it tomorrow, but I can't
promise anything.

Uh... Update, folks! (and I gotta name this thing now... how about

It boots! Did I mention that it came with one floppy disk stuck in the

You're right, but they seem to format to only 320K (8 sectors/track, not 9)
with the DOS I do have, which is listed in the stats of the machine I
listed below... The broken drive *does* work! It's only the door that's
broken, so I sacrificed my Atari 810 (which was dead anyway) and the garage
door from it is exact! Yiippee!

Whaddya did with the rest? A few spare parts might be nice (or a color

I don't doubt your memory, but I think this is a (prolly earlier) version
of the monitor rom... specs to follow. I fat-fingered *all* the keys on it,
and here's what works:
B -- boots. Accepts parameters of: 0, 1, 2, 3, and that tells it what
floppy to boot from. Plain B assumes floppy 0, which is top. Thanks! All
else beeps with invalid parameter, except "S", which appears to do nothing.
Would this be boot from the serial port, perchance?
V -- Version of the monitor rom, which is Version 1.02.
Nothing else worked...

This thing came with a Version 1 Dos... here's the specs of the boot:
Z-DOS / MS-DOS BIOS Release 1.00 Version 1.02
Z-DOS / MS-DOS Release 1.00 Version 1.25

I've pulled 'er apart to fix the floppy, and to clean the keyboard & all.
Sure enough, it has a NEC 8085A plastic, and an Intel 8088
like-eprom-whatever-you-call-it case. It presently has 128K RAM in it!
Questions:
1. Whilst it's all apart, does anyone want me to snap pictures? I can...
2. How high can this rascal go in memory? I located 3 banks (9 each --
parity) of 64kx1 300ns DRAM, two of which are populated. Mathmatically,
that works to: 128K RAM. The third bank is empty. Can I pop in 9 more chips
without setting any jumpers/dipswitches? How about bigger DRAMS? (prolly
not... but it's worth an ask!) Still, 192K is still pretty good for a
machine from '82!
(also, on the question of jumpers... anyone have a tech-like manual for
this thing I could get a copy of... or at least a copy of the important
pages?)
3. The video board which is based on the Motorola 68A45P video chip,
presently has 64K onboard for *just* the green section of the board. This
rascal can handle 192K Video Memory!!! Funky! ;^> (that is, if I'm reading
the boards right.... but CHKDSK doesn't return the added video memory, so
that'd seem correct.) Does the board support any form of graphics? I tried
the standard basic commands (ZBasic was on the floppy) but it seemed only
to work in text.
For this thing having 2 Intel-based processors, I'm surprised with the
amount of Motorola logic in this rascal! Prolly a 3rd of it is Moto,
including the 74 series chips! All of the important support chips, like the
video processor, the PIA's & UARTS, and all that jazz seem to be Moto.
Well folks, I havta say: This is one *sweet* machine! :-)
>I'm not sure what the licensing requirements are, however, I do have
>several OS's for the machine - I'm sure something can be worked out.
Did Heath/Zenith bundle an OS with the disk systems? If so, wouldn't I own
a license to own a copy of the included OS, as I own the machine? I'm not
sure how stuff like that works, especially on the old stuff.

No prob... I'm behind as well, as you can plainly see!

Somewhere I have docs on the WD1002-05 which, IIRC, has a WD1000-compatible
hardware interface. The exception is that the WD1000 supplies a WAIT signal
and the WD1002 doesn't.
"The WD1002-05 has been designed to interface to a Host processor via a
parallel port or CPU bus configurations. The specific signals are compatible
with the WD1000/WD1001 series of Winchester-only controller boards. With the
inclusion of the WD1015, the previous WAIT signal is no longer necessary,
but has been provided for compatability; status information is always
available to the Host for monitoring command progress. When the Busy bit
is set, no other status bits are valid."
The host connector is a 40 pin connector. Of this, all even pins are grounds.
The other pins are:
1 -15 : DAL0 through DAL7 respectively
17-21 : A0 through A2, respectively
23 : CS
25 : WE
27 : RE
29 : Pulled up on the WD1002; this is probably WAIT on the 1000.
31, 33: Not connected
35 : Interrupt request
37 : DMA request
39 : Reset
I suspect the interrupt request, DMA request, and Reset ar all asserted high;
the photocopied manual section I have doesn't make this clear.
The WD1002 is programmed like an IDE controller with an 8-bit data register.
I suspect the WD1000 is as well.

OK, a few things about VMS.
To break into VMS, boot it /1 like this:
>>> b/1
It will give you a SYSBOOT> prompt, at which time you tell it to use
the console for the startup command file:
SYSBOOT> set/start=opa0:
SYSBOOT> continue
Then it'll boot farther and give you a $ prompt. What I usually do here
is this:
$ spawn
<<< spawning SYSTEM_1 message >>
$ @sys$system:startup
This executes the startup file. When the startup file exits, you get the
$ prompt back. At that point, you can:
$ spawn
$ set def sys$system:
$ mc authorize
UAF> set system/password=whatever
UAF> ^Z
$
At this point, you can either shut the system down:
$ @sys$system:shutdown
[[[ you can punch return to all the questions ]]]
and power cycle the system or just hit the power switch. Unlike Unix,
VMS doesn't eat the disk if the power goes out unexpectedly; normally, you'll
want to shut it down with the shutdown command, though (what happens if any
files are open is that blocks allocated to those files are marked as
allocated in the bitmap but not recorded as belonging to those files in
the directory; if you just turn the power off, you'll essentially lose
space on the mounted disks that have open files).
The next time you boot, the system will remember that it wants to use the
console as the startup command file, so you'll have to do the "conversational
boot" again and set it back:
>>> b/1
SYSBOOT> set/start=sys$system:startup.com
SYSBOOT> continue

Absolutely nothing. It's a standard 300 baud modem.

Nope, I'm referring to a plain old Novation CAT 300 baud acoustic coupled
modem. I saved it from the trash heap a few years ago because I was going
on travel somewhere that I knew A) I would have to do some remote access
>from my hotel room and 2) the hotel room didn't have modular jacks. It was
the only acoustic coupler I could find and worked great. I haven't had
the heart to toss it out since.
BTW, this would have been about '92 that I was using 300 baud modems from
hotel rooms...

Here's a real classic for ya. I'd have killed for a system like
this one, but married life, no room, no time, blah blah blah . . .
Maybe someone out there wants this.
