I believe the DOS version was PC-DOS 2.11. From reading previous posts on
this list, and other places, the floppy drive in the PCjr was fairly
flimsy, so if may be a "standard" problem.

It is IBM's clone of the PC/AT with a few exceptions.
Hmm, I'm sure you don't mean "IBM's clone of the PC/AT", since IBM could
hardly clone their own product. The XT-286 is actually a warmed-over PC-XT
motherboard design, adapted to use the 80286 CPU. It was a product
positioned in between the XT and the AT in IBM's lineup.
3. Some AT boards will not fit into it.
Actually, no AT boards will fit into it. Although it used the AT's 286 CPU,
it retained the XT's 8-bit bus, and was limited to 640K RAM (no 16-bit RAM
expansion available). In a sense, you can almost think of it as a "286SX",
since it is largely analogous to the 386SX in that it had a bus half the
width of the CPU internal core (although I'm not sure whether the
motherboard RAM was 8- or 16-bit). The XT-286 failed, not just because of
its limited expansion versus the AT, but due to competition from the Turbo
XT (8-10MHz 8088/NECV20) market, which had similar performance.

I have an XT/286 in a box and used it for many years.
It is IBM's clone of the PC/AT with a few exceptions.
1. It uses an XT case
2 It is 6mhz with 0 (zero) wait states.
3. Some AT boards will not fit into it.
Due to the zero wait states it is faster than other 6mhz AT's that do
have wait states.

I have recently came into position of an old Xerox computer that I
really do not know much about and was wondering if anyone out there
would be able to send me via e-mail any info that they may have on it.
The computer works and all but all that comes up is something about
tables and something about invalid drives. If anyone out there has any
info on this computer I would greatly appreciate it.

You can look at http://members.tripod.com/~apd2/catweasl.htm for an ISA card
that'll (allegedly) read several MFM and GCR formats, including Commodore,
Amiga, FAT, Atari, Macintosh, and Apple //.
I haven't ever used one, so I can't comment on its reliability, but it might
be worth investigating.

Of course you have to realize that this is an NC (in the modern sense). A
VAXmate worked really well in a network environment with a VAX at the far
end running Pathworks. I remember setting one up in 1987 and being
impressed with what you could achieve. It was really nice being able to
store PC data on our VAX which we backed up properly!
Of course, like DECs other NC (the Multia) they were ahead of the market
and couldn't sell them to save themselves :-(

That fits. I have a copy of 1.02, the "International Version" with files
dated 1/86.
Hans Olminkhof
Ah, I got the answer... there was a 1.01 with a limited release in the US
only, I still have yet to get confirmation over whether there was a retail
store package or whether it was bundled only. 1.03 was indeed the first
multinational release about 9 months later.
I'm sure there wasn't a 1.00, although 1.01 packages may have carried "1.0"
markings.

Sorry Kai, I usually tend to take your MS statements as gospel but in this
case I've just been looking at the flash page and desktop of Windows 1.01
copyrighted 1984 and the files are dated 11-15-85. Unless this was a pirated
version smuggled out of MS or an elaborate put-on it must be the first
issue. It has a somewhat-Norton Commander style desktop but has most of
the utilities of the later version - notepad, write, calendar ,etc. and a
pif-editor and win.ini. It comes on 5 360k disks with a set-up program that
builds a small Win.com and an much larger overlay binarie. As you mention it
doesn't support VGA and the readme file has a lot of references to problems
with AboveBoard (the Intel mem-expansion card). I've had it for a short
while
and just now installed it on an 8580 PS2 running DRDOS. While I can get the
desktop the utilities hang with the familiar hourglass.
I just tried it on my 5150 which has an Inboard card and uses the A20
handler but only 1meg memory and also heavily configured and with Dos 5. It
crashed leaving me at the prompt. Using my favorite shell CMFiler got me to
a blank screen before crashing . Likely memory related.

The 34-pin control cable for ST-506 interfaces can either have a twist
or be straight through where you need to alter the HDD drive selects
accordingly.
The 34-pin control cable used on ST-506 interfaces doesn't care
whether it lives in a PC PC/XT or PC/AT environment.

The AT MFM disk control cable (for ST506-like hard disks) certainly has a
twist in it. This twist swaps over 2 of the drive select lines between
the 2 drives, so they can both be set to the same drive number. I will
have to get the manual if you want the exact details.
I think the XT control cable does as well. I have an XT somewhere with 2
ST412 drives (in the 5161 expanasion box) but I'd have to dig it out to
check if the cable has the twist.

With what? if each other the answer is not at all. The Rainbow
was sorta PC(ish) using z80 and 8088. The DECMATE used a PDP-8
cpu reduced to a chip. Differences, PDP-8 is a 12bit machine
and the other two should be familiar.

The used a similar box, same Floppy (RX50), if it was installed the

EDSI does not generally use the twist unless that was a PC hack. The

as a pair of MFM drive on a WD 1003/5/6 controller.
The only thing in PCs I know of that use a twist cable is Floppies.

ESDI cabling is definitely the ST506/412 interface used on old MFM
(e.g. Seagate ST-225) or RLL (e.g. Seagate ST-238). If the 34-pin
control cable is straight through (without the twist) select drive 0
if the selection is 0 and 1. If the selection is drive 1 and 2, select
drive 1 (nomenclature varies among manufacturers). Ensure the
terminating resistors are installed or you are asking for trouble.
If the 34-pin control cable has a twist and you have only one drive
attached to the end of the cable with the twist, use drive select 1 if
your drive nomenclature is 0 and 1. If the drive select nomenclature
is 1 and 2, select drive 2 and make certain you have the terminating
resistors installed.
Two drive scenario:
34-pin control cable with twist, drive at end of cable with twist use
drive select 1 if drive has 0 and 1 as drive selects or 2 if using 1
and 2 drive selects and again ensure the terminating resistors are
installed in this drive. The drive in the middle of chain should use
drive select 1 if drive has 0 and 1 as drive selects or 2 if using 1
and 2 drive selects (yes, use the same drive select as the C: drive
attached to the end of the cable) and make certain the terminating
resistors are removed from this drive which will be seen as D: drive.
If the 34-pin cable has no twist, C: drive is set for 0 (if drive
selects are 0 and 1) or 1 (if drive selects are 1 and 2) and
connected at the end of the cable with the terminating resistors
installed; D: drive is set for 1 (if using drive selects 0 and 1) or 2
(if using drive select 1 and 2), connected in the middle of the chain
and must have the terminating resistors removed.

In trying to finf info re my Wang , Wang Users Group turned up empty, so
I did a general search on "Wang". What fun. I found out there's a hell of a lot
more Wangs than Jones out there. And a good proportion of them are scientists.
Wangs like to display themselves and one even had pictures of his wife and
his sister on his page.
Among the Wangs on display were Joy C Wang, Junping Wang, Leiping Wang,
Linping Wang and the saddest, Weiping Wang (maybe a pseudonym for linping)
There was Gang Wang and Wang Man but the most impressive Wang was :
Wang Jinrey a fighting philosopher
Nationality China
Fighting Style shin-irokugoken
Age 84 Height 165cm Weight 56kg
Bloodtype B
I was especially impressed that they included this fighting philosophers blood
type.
I also found out that bin wang wasn't a binary file and wang fan wasn't a
computer enthusiasts group.
There was also a geographical perspective with the Phuket jewelry shop in Wang
Talang Siam , the King Wang Hotel in Taiwan, and the Wang Centre for the
Performance Arts in Boston.
There's also a Wang differential geometrical theorum used wildly by
scientists.
Then I dicovered I could finger wang@risc and after 60 Lycos pages of URLs
with nary an end in site ,my energy petered out I was getting giddy and
laughing hysterically at every Wang thang . There's just too damn many Wangs
out there and I exited without finding any references to my Wang..
On a less humorous note I did find a UK source for Wang
and NEC as well as other laptop batteries. MDS Batteries.
Likely pricey to ship them this side of the pond but they did
have some specs so maybe one could make yer'own.

Systems with 'DECstation mumble' should be MIPS, but if it

Once you get the nose on, the rest is just makeup.
Good grief what a week this has been, but I finally got the PDP-11 I'm
trying to put together to boot off of a ESDI harddrive. Not the processor
or disk controller I was expecting, for all that goes not the version of
RSX-11M I was expecting, but it's up and running.
At the moment it is running a PDP-11/23+ instead of the /73, has a RLV12 in
it, and is missing basically all the boards. However, tomorrow I'm hoping
to basically get the hardware back into the configuration that I want.
I had two problems. First, for some reason I couldn't get RSX11M to like
the Webster WQESD controller I was trying to use, so I switched to a Emulex
QD21, and was able to load the TK50 onto the Harddrive. But it wouldn't
boot once I got that done last night. Foolish me thinking it wasn't
bootable drug a RL02 drive and controller into the house tonite :^( Turns
out that I'd gotten the DIP switches mixed up <ARGHHH> Once I had them
right (and the system totally rearranged) it booted off DU0: despite my
wanting to go from DL0: :^)
If work doesn't interfere tomorrow night, I'm going to be having some fun
with this system :^)

To the best of my knowledge, there was no Windows 1.00. As I recall, we
released 1.03 as the first version.
1.03 was available only on 360K 5 1/4" and had no VGA support. 1.04 was the
same as 1.03 except it was available only on 720K 3 1/2" and supported the
PS/2 _exclusively_.

That's what I thought. I have 2 of the WANG WLTC's (that's why I'm trading
one). The other one has worked fine for about 1 year (and longer with the
previous owner) with the Tyco supply. The other keeps blowing. I think
it's being caused by some weak components elsewhere in the circuit (some of
the other caps may be beginning to deteriorate).

Good point. the answer is simple... What is te voltage rating of the

I have one of the Andromeda ESDC controllers for qbus pdp-11s, and it
has four connectors on it. One wide one (like the wide MFM one) and
three of the narrow ones. According to the documentation I have, one
could attach up to three drives to the one controller, possibly up
to six with some sort of adapter... (It also support floppies with
an adapter, but I don't have that)

Questions came up last week about how much power a DECsystem-1090 CPU (KL10)
consumes, and how the power supply works. Tony Duell suggested that the KL10
might not consume any more power than a big PDP-11/45 system; I disagreed.
My previous description of the power system was not entirely accurate, so I've
dug out some technical documentation, including the manual "Power System
(1080/1090) Interface Description", part number EK-PWR1-ID-002, dated March
1977.
The KL10 CPU cabinet consists of three bays. In a 1080 or 1090, the middle
bay contains the main CPU card cage, which has 47 extended hex modules full
of ECL logic.
The left bay (as viewed from the front) contains an I/O card cage containing
up to 50 extended hex modules full of TTL for the RH20 Massbus channels, DTE20
front-end interfaces, DMA20 memory bus interface, and DIA20 I/O bus interface.
The right bay contains a PDP-11/40 front end processor, a TU56 dual DECtape
transport, and a TC11 DECtape control.
Note that this does not include any memory or peripherals necessary to
make a complete system. I am going to describe only the power requirements
of the CPU cabinet.
All KL10 models require three-phase power. The KL10-AA and KL10-BA models
operate on three phases of 90-132 VAC 60 Hz (208 VAC nominal phase-to-phase)
The KL10-AB and KL10-BB operate on three phases of 180-264 VAC 50 Hz (416V
nominal phase-to-phase). Total input power is specified as 12.6 kW typical
for a basic system; a real-world configuration would have more DTE20 and
RH20 units, so it would consume more power.
Needless to say, the power supplies in the KL10 are not power factor
corrected. The 863 three-phase power control has a 75A main circuit breaker.
Unfortunately I do not have a copy of the DECsystem-10 Site Preparation Guide,
so I don't know what the actual specifications for peak current per phase
are.
With the exception of the power supply for the main CPU cage and the cooling
fans for that bay, most of the machine actually operates on single phase
power. The various fans and power supplies are distributed between the
phases to balance the load.
The CPU cage fans operate between two phases (208V) in the -AA and -BA models,
and between one phase and neutral (240V) in the -AB and -BB models.
The power supply for the ECL consists of an H760A or H760B raw power supply
(depending on the line voltage), a 70-09475 capacitor assembly, and an H761
regulated series pass assembly.
The H760A/B contains three ferroresonant transformers with primaries wired in
a three-phase delta. The secondaries are center-tapped and wired with
half-wave bridge rectifiers. The output is -12V at 490A. The diodes are
mounted to a massive heat sink with its own fans.
The capacitor assembly consists of thirteen 0.3F capacitors in parallel for
a total capacitance of 3.9F. The output under full load is -11V+-10%.
In the event of a power failure, this is sufficient to allow a hold time
of 20 ms before the voltage drops below -7.5V.
The H761 regulated series pass assembly consists of 13 linear regulators.
Nine have -5.2V 35A outputs for the ECL main power, and four have -2V 35A
outputs for ECL termination. There is room for a 14th linear regulator
which is normally not installed.
The maximum load for the CPU card cage is thus (9*5.2V*35A)+(4*2.0V*35A), or
1918W. At that load, the input power required by the power supply is
over 5460W. This is less than 35% efficiency.
Of course, the ECL power supply is nowhere near the whole story.
The following additional power supplies are in the system:
quant model output use
----- ----- ------ --------------
1 H720 +5, -15 DECtape system
1 H725
1 H7420 AC power supply PDP-11/40
3 H744 +5
1 H745 -15
1 H754 +20, -5
1 H732 0-20VDC margin check
1 783-C +10, -15
1 H7420 AC power supply
1 H744 +5V CPU cage TTL supply
2 H744 +5V I/O cage DTE20 TTL supply
1 H744 +5V I/O cage RH20 TTL supply
1 H7420 AC power supply
4 H744 +5V I/O cage RH20 TTL supply
1 H7420 AC power supply
1 H770 +15V air flow sensors
1 H745 -15V I/O cage DIA20/DMA20
3 H744 +5 I/O cage DIA20/DMA20 TTL supply
I have not found any figures for typical current used by the various
subsystems. However, the ratings of the regulators are:
H720 5V 22A, -15V 10A, unregulated -22V 1A, unregulated +8V 1.5A
(unregulated outputs not used in KL10)
H732 0-20V 5A
H744 5V 25A
H745 -15V 10A
H754 +20V 8A and -5V 1A
H770 +15V 10A
DEC didn't waste any more money on regulators than necessary, so it is
a safe assumption that a fully configured system will use most of the
available DC power, which for just the +5V supplies alone is 1860W.
Fortunately the power supplies used with the H7420s are switchers, so they
are probably at least 65% efficient.

The only PC ESDI controllers I have ever found all have 2 data cable
connectors (20 pin on the card), which can each connect to one drive only,
same as MFM. In fact right now I can't think of any differences between ESDI
and MFM cabling for PC's. Not sure about the twist details though.

Hello everybody.
I have a WANG WLTC laptop computer (circa 1980's). I do not want to sell
it for cash, but I'd be willing to trade it for another unusual
portable/laptop.
Here's some specs on it:
-NEC V30 (8086) processor
-10MB Winchester Disk
-External Centronics-type SCSI port (HD is also SCSI)
-Built-in thermal printer, with roll/cut sheet capabilities
-512K RAM
-RS232-C Serial port
If you're interested in it, email me, and I can send you more info and/or a
picture of it.
There is, however, a problem with the internal (regulating/switching) power
supply. It runs the computer, but keeps blowing a capacitor. It also
needs an external P/S and battery. The battery is 10 sub-cells (with a
resistor - I have a schematic). A Tyco 20VDC racing transformer (the kind
for the little car/track sets) will run it.
I had an offer to trade it for an IBM PC-Radio, but I never got a reply.
If anyone has one of these, or any other odd or unusual laptops/portables,
and would be willing to trade, let me know.
ThAnX,

ESDI cables for PC's may or may not have a twist. The drive has a jumper
(usually marked drive 1 or 2) that must be set accordingly.
I've had a lot of trouble getting old ESDI drives to work also, especially
with Western Digital controllers. I thought all my drives were bad until I
found a Future Domain controller that worked with most of them. The drives
also need to be low level formatted by the card being used.

1 - PDP11/44
1 - TS11 Tape drive
2 - RMO2 Drives
2 - Systems Industries Drives (680Mb, 390Mb)
1 - DEC LP25 Printer
We are willing to entertain any reasonable offer for this equipment. We
are also willing to donate this
equipment to any charitable or educational institution. If you are
interested in this equipment, email
either myself at the address below or Joyce Zogott at jzogott(a)uarts.edu.

You could boot probably all of the sixteen scsi devices (if you have two

Vaxstations 3100/xx.

A few months ago, I picked up a scavenged non-working MicroVAX
and a little VaxStation 2000/VS410 from a junk storeroom at
Nicolet Instruments in Madison, WI. I'd missed a pair of much
nicer graphics-equipped MicroVAXes dumpstered a month or so before.
I've received word that they're clearing out this storeroom.
I know there'a a TK50, carts, manuals and lots of other misc. junk,
including several Cypher (?) mag tape units.
It was piled high and deep and very poorly organized. There's
also a rack-mount Nicolet 1280 that was known-working when retired.
Mr. Ismail, you have a 1080, would you like another from the
Nicolet family?
I'll pick up what makes sense, and post a list. I doubt I'll want
to keep it all.

Looks like it's a 3100 Model 38... can someone point me to video

I'm wondering if it will drive any of the Sun Sparcstation monitors
without a problem (or a modern multisync). At worst I'll run it

As soon as it arrives I plan to load it with VAX/VMS from the

Along with the Compaq books and the Jonos Escort previously
described, I just stumbled (literally!) over the other bit of
vintage digital gear.. an unopened/shrink wrapped box containing an
AT&T Voicepower VP1 module for the 6300 series. The box is marked
"Work Group System Voice Power"
I haven't opened it yet, but there was a stack of about 25 of
them, 20 of which had been sold en masse.
Apparently it is a trainable voice-input command module. Along with
it (unrelated) was the AT&T version of the IBM user's guide for the
6300, with disks. Since I have two 6300s skulking around here, I can
hook this thing up and see what happens...
The VCF II sounds like it will do more than was thought to further
the aim of Thechnology Preservation.... but that's why we do this, no?
