there was some previous discussion about nec multisync monitors. believe it or
not, i actually found one tossed in the partking lot of an auto parts store.
<!> unfortunately, it wont power on. made in 1990 and has XGA plug. anybody
want it for free or need parts from it? it has a lot of controls behind a flip
down door. no burn-in on the tube amazingly.

Of course the coolest thing about 'core' is it's the original
non-volitile memory; you could carry one around with a diag
utility already loaded, just plug it in and run.
One of the myth's they always told us was they all had to be
made by hand - there wasn't a machine that could thread the
row/column and sense wires for mass production. Is there any
rumor to this truth?

I have been offered a Tektronix 3003 box with a 15" Mitsubishi
monitor.. it came from a scrap yard via a guy who does movie prop
rental, with whom I have a standing order for DEC stuff... wait,
what I mean is... oh never mind!
:}
Is this Tek box of interest to anyone on the List? I have no
knowledge of/interest in Tek computers.

I picked up two notebooks full of Apollo (not HP) disks and manuals. One
is for C language and the other is Ether Controller, Ether Bridge and
TCP/IP, etc. Does anyone need this? If so, I'll consider swaps, if not
I'll toss the manuals and reformat the disks for use with my Intel.

I picked up a couple of old CPM disks that are marked "CPM Startup for
ZVX4" and "SCS-D07-1". These were made by Sorrento Vally Associates,
Sorrento Vally Rd, San Diego and have 1980 and 1982 dates. Does anyone know
what kind of system they're for?

Fact is, I have seen facilities (by photograph though) in Japan where IBM
manufactured
core planes, by hand. The pictures probably came from the early '60s but,
they clearly
show ladies sitting at circuit board mounting tables, large magnifying
glasses with
integral florescent lamps, and core plane frames mounted in circuit board
holders for
easy working. I am sure that machines were constructed but, I am also sure
that some
of the earlier work was done by hand.

I'm looking for info on what looks to be either a very old or obscure IBM type
number. All I have is 3848 and "VTL" (card) to work with. None of the search
engines, including Deja News, come up with anything other than a "help wanted"
listing looking for someone with experience on the 3848.
Any idea what this might be?

I have never ordered from the guy, because I smelled a skunk. The
only info I have came from his own ads and web pages; I have not
actually been "done wrong" by him. The pictures do look great,
and if everything looked consistent with that, I'd have probably
ordered one or two myself.
But here I'll quote from his web page, which lives
at http://www.netw.com/~drfcline/univac.htm :

The ellipses were just some happy talk about how cool cores and Univacs
were. I agree with him there, wholeheartedly. But those last two
sentences sounded to me as if there were no cores to be had. If he
had them for sale, how could be be calling them "long gone"?
Well, okay, we have at least one confirmed order in which cores are
really present, and nobody griping about getting ripped off. The
only sane conclusion is: you are right, I mis-read it in a big way.
Guess I'm so used to scams that I'm seeing them even when they are
not there.
Thanks for the correction! On top of setting me straight on something
that I felt bad about, this means maybe I can talk myself into (out of?)
ordering one! :-)
Apologies to Dr. Cline, and to the list, for my outburst.
Bill.

Beware; in the past this guy has offerred "core memory planes" for
sale several times, even on this list. But if you had read the
fine print you would have found that there were no cores - just
the rectangular PC-board "frame" in which the cores used to reside.
I suppose you could call that a plane, but it isn't what most
compu-geeks would think when hearing the word in that context.
In this case, he includes some text from an "actual" customer
ranting about how cool his core memory board is, describing at
length the 1024 core bits and yada yada yada, but if you read
the all the way to the end you'll find that what he's actually
offerring are the controller cards - not the 1K bit planes that
he describes in such detail. Classic bait-and-switch.
In fact, even when he was earlier selling the core memory boards,
they didn't have the cores, so this rant is obviously marketing
delirium. Nothing that is an outright lie, but misleading as Hell,
unless somebody actually things a PC board frame with no components
is awesomely cool and "looks great under a microscope". Tell me
that isn't engineered to fool people into thinking they're getting
real core memory. Sheesh! And "whatever was last written (back
in the 50s) on the planes I bought is still there" - nope, not
"there" as in "on the planes I bought", but "there" as in "wherever
those cores happen to be now".
As far as I'm concerned, this guy is a rip-off artist. If he
was simply selling Univac memory controller boards, I'd be more
than half interested. And oddly enough, as near as I can tell,
these controller boards actually *do* have some core bits left
on them. (Are "windings" the same as cores, or is this another
aspect of his marketing ingenuity?) So in that sense they may
be more interesting than his former offerings.
Anyway, seeing how far he'll go to be misleading, I don't trust
him. I get the feeling that if I read enough fine print, I'd find
that he's actually just selling pictures of those things, or
pictures of something else that had once been in the same room
with those things, or...
It's really a shame that something like a Univac memory unit would
end up in the hands of somebody like this, who would hack it to
bits and then try to sell the broken fragments by being so misleading.
Sadly,
Bill.
PS. I suppose it is possible that he once sold an actual core plane
with cores in it, and that's what this testimonial is describing.
But the first time I saw that ad of his, I rushed over to his web
page and found him offerring "coreless" memory planes. And even
then he was ranting and raving about how cool cores were, in the
same way he does here, only mentioning at the end that these boards
don't actually have any core. So again, there might not be any
outright lies in any of this, but be sure to read *ALL* of the fine
print before you consider dealing with this guy.
I got this from one of my friends who works at my upstream ISP. This was
hilarious, I just had to share it!

[from Zeno, to a whole bunch of people]
I know my friend Pat, lover of tele-marketers, will get a kick out of this
one:
Me: Hello
AT&T: Hello, this is AT&T...
Me: Is this AT&T?
AT&T: Yes, this is AT&T...
Me: This is AT&T?
AT&T: Yes This is AT&T...
Me: Is this AT&T?
AT&T: YES! This is AT&T, may I speak to Mr. Robinson please?
Me: May I ask who is calling?
AT&T: This is AT&T.
Me: OK, hold on.
At this point I put the phone down for a solid 5 minutes thinking that,
surely, this person would have hung up the phone. I ate my salad. Much to
my surprise, when I picked up the receiver, they were still waiting.
Me: Hello?
AT&T: Is this Mr. Robinson?
Me: May I ask who is calling please?
AT&T: Yes this is AT&T...
Me: Is this AT&T?
AT&T: Yes this is AT&T...
Me: This is AT&T?
AT&T: Yes, is this Mr. Robinson?
Me: Yes, is this AT&T?
AT&T: Yes sir.
Me: The phone company?
AT&T: Yes sir.
Me: I thought you said this was AT&T.
AT&T: Yes sir, we are a phone company.
Me: I already have a phone.
AT&T: We aren't selling phones today Mr. Robinson.
Me: Well whatever it is, I'm really not interested but thanks for calling.
When you are not interested in something, I don't think you can express
yourself any plainer than by saying "I'm really not interested", but this
lady was persistent.
AT&T: Mr. Robinson we would like to offer you 10 cents a minute, 24 hours a
day, 7 days a week, 365 days a year.
Now, I am sure she meant she was offering a "rate" of 10 cents a minute but
she at no time used the word rate. I could clearly see that it was time to
whip out the trusty old calculator and do a little ciphering.
Me: Now, that's 10 cents a minute 24 hours a day?
AT&T: (getting a little excited at this point by my interest) Yes sir
that's right! 24 hours a day!
Me: 7 days a week?
AT&T: That's right.
Me: 365 days a year?
AT&T: Yes sir.
Me: I am definitely interested in that! Wow!!! That's amazing!
AT&T: We think so!
Me: That's quite a sum of money!
AT&T: Yes sir, it's amazing how it adds up.
Me: OK, so will you send me checks weekly, monthly or just one big one at
the end of the year for the full $52,560, and if you send an annual check,
can I get a cash advance?
AT&T: Excuse me?
Me: You know, the 10 cents a minute.
AT&T: What are you talking about?
Me: You said you'd give me 10 cents a minute, 24 hours a day, 7 days a
week, 365 days a year. That comes to $144 per day, $1,008 per week and
$52,560 per year. I'm just interested in knowing how you will be making
payment.
AT&T: Oh no sir I didn't mean we'd be paying you. You pay us 10 cents a
minute.
Me: Wait a minute here!!! Didn't you say you'd give me 10 cents a minute.
Are you sure this is AT&T?
AT&T: Well, yes this is AT&T sir but......
Me: But nothing, how do you figure that by saying that you'll give me 10
cents a minute that I'll give you 10 cents a minute? Is this some kind of
subliminal telemarketing scheme? I've read about things like this in the
Enquirer you know. Don't use your alien brainwashing techniques on me.
AT&T: No sir we are offering 10 cents a minute for.....
Me: THERE YOU GO AGAIN! Can I speak to a supervisor please!
AT&T: Sir I don't think that is necessary.
Me: Sure! You say that now! What happens later?
AT&T: What?
Me: I insist on speaking to a supervisor!
AT&T: Yes Mr. Robinson. Please hold.
So now AT&T has me on hold and my supper is getting cold. I begin to eat
while I'm waiting for a supervisor. After a wait of a few minutes and
while I have a mouth full of food:
Supervisor: Mr. Robinson?
Me: Yeth?
Supervisor: I understand you are not quite understanding our 10 cents a
minute program.
Me: Id thish Ath Teeth & Teeth?
Supervisor: Yes sir, it sure is.
I had to swallow before I choked on my food. It was all I could do to
suppress my laughter and I had to be careful not to produce a snort.
Me: No, actually I was just waiting for someone to get back to me so that I
could sign up for the plan.
Supervisor: OK, no problem, I'll transfer you back to the person who was
helping you.
Me: Thank you.
I was on hold once again and managed a few more mouthfuls. I needed to end
this conversation. Suddenly, there was an aggravated but polite voice at
the other end of the phone.
AT&T: Hello Mr. Robinson, I understand that you are interested in signing
up for our plan?
Me: Do you have that friends and family thing because you can never have
enough friends and I'm an only child and I'd really like to have a little
brother...

Ugh. These were incredibly expensive and each mechanism would

Around 100k. It was faster than audio cassette but clower than floppy.
It's search speed was terrible.
I did a design before it came out using a 8track cart for a platform.
It's problems were using the short loops I made it would take 180 seconds
to search for the previous block and the reliability of the tape was poor
with oxide flaking (even using the best mylar tapes). While I was able
to make it work I abandoned it within weeks of building it for a DC300
cartridge and my own drive. Based on my experiences with looped tapes
and carts when I saw the Exxatron I regarded it as unlikely contender.
It didn't last long.
It is very collectable as likely few survived.

It's me again,
To help fill-in my technical library for the equipment I have, I would like
to buy good copies or originals of DEC documents for the the following
hardware:
** PDP-11/34A System User's Manual. I have an earlier 11/34 System User's
Manual (# EK-11034-UG-001) which has some 11/34A stuff in it but evidently
not up-to-date with the 34A processor I've got. There should be an updated
one later than the EK-number above which is closer to my system.
** KD11-EA Processor Manual (for 11/34A). Document number: EK-KD1EA-MM or
later.
** RA60 drive printset. I have to fix one that won't spinup.
** RA60 technical manual. For same reason....
** VAX 11/730 - Technical or operating manuals, printsets, ANYTHING AT
ALL!! I have nothing. Tony Duell needs those documents too for his machine.
** MicroVAX II (model KA630QY-A2) user's manual and a technical manual or
anything else for that matter.
** Emulex TC02 manual and any tech manuals.
** PDP-11/04/34/etc. Processor Handbook. Part number EB-09340 or later
(for 11/34A processors). Should be an original and not a copy of course ;)
That's all for now. I still need others but these are more important.
Thanks for the help!

i was talking to my manager who is just about ready to give me a complete and
working trs80 model 1 with ALL accessories. he also said he used something
called a stringy floppy with it which used a loop of string/wire to save data
with not quite the speed of floppies but certainly faster than cassette. has
anyone seen these or can explain how they work? he said there were carts that
were put into the drive so it seems to be a removeable media device? can
anyone explain further?

Hi folks,
Recently I posted that my MicroPDP-11 is up and running. A question I had
still is not answered and I was hoping somebody here could help.
The machine has a Syquest cartridge drive. It is a model SQ 312RD.
I tried searching the web for info on this model but could only find a
reference to it having 2 heads and 615 cylinders. This figures to
10,705,920 bytes capacity assuming 17 sectors per cyl and 512 bytes per
sector? 10 mb cartridge size then, correct?
I have no other info on Syquest except they are now dead (their websites
still turn up in search engines but there's no response.) Anybody fill me
in on the specs, etc?
Cartridges available for the SQ 312RD????
Any other tape/cartridge drive available you recommend I should replace
this with? I have an Emulex TC02 controller in this box. Don't even know if
the Emulex board works as there's no cartridge to try the Syquest with.
Is there a Pertec-formatted tape drive which can hang off the Emulex which
is half-height, 5.25" form (to replace the Syquest)? This is ideal since I
can keep the 5.25" floppy drive.
What if I find an external-mounted TK50 drive and TQK50-AA (M7546)
controller and fit it into this system? Is this workable?
Will RSX-11M+ ver. 3.0 handle a TK50??
Software drivers??
I have no other way to back the system up at this time (floppies are
probably out of the question because of quantity needed and huge PITA-factor)
Thanks for the help!
Regards, Chris

Nice site, lots of great links too. One problem though. I tried to
access your RQDX3 documentation but got a 404 not found error. The
links to this doc still point to the old site, which seems to be
empty. Will you reload the RQDX info? Many thanks in advance.

Anybody have a junker TK50 with the plastic tape leader still intact? Or,
does anyone have a NOS part? I would like to buy that part to repair my drive.
Mine has broken on one side of the position aperature through which the
photodiode detects its position. Looks like it has been broken awhile as
the tips of the break are a bit rounded with wear from the previous owner
continuing to use it (probably never knew it was broken). I don't want to
take a chance with it breaking on me while most of a tape is wound up on
the takeup spool!
Thanks, Chris

Haven't been there this time, but it's nice, althrough
my kind of computer museum would be a bit more on the
variety of the 70s and 80s focused. Also the HNF Computer
Museum is a _bit_ company specific (ok, not as much as the
Tupperware Museum). Son't get me wrong, it is still VERY
impressive and the most comprehensive of all existing
Computer/Information Technology museums in the world (at
least compared to everything I have seen until now). And
compared to the computer department of the Deutsches
Museum, all displays are finished in an usefull way (As
you might have noticed, I'm still mad about the displays
at the Deutsches Museum).

I'd recommend:
1. Get one of those rubber holsters for the meter and allow only the
holster to touch the equipment.
2. Make some test leads out of EHT wire. The sort of stuff that's used
for the anodes of CRTs and things. Maplin used to sell it (haven't checked
recently), rated at 25 kV, and I'm sure other suppliers do too.
3. Failing no. 2, car engine HT leads may be useable, but most of them are
quite rsistive, so check the calibration!

Hmm - "$" is what I've always seen with the 11/34A ROM's. Is
it possible that you aren't running the standard 11/34A ROM's?
What are the DEC ROM numbers on your 9312? The part numbers
will be of the frm 23-nnnA9, where "nnn"=752 for the RK06/07
bootstrap. Sometimes the "23-" is left off.
But the register printout is correct...

On topic, I've tinkered with a number of monitors, and some really old
ICL Terminals that we maintained for a small company in town that had
some strange system. They had some interesting fault modes.
(Circuit diagrams were non-existant of course)
Ok, I'll bite, what in heck is a LART.
I've seen this in NANAE but have no idea what it means in this context.
I should also mention that when I got home that afternoon, after I realized
just
how close I came, I made a quiet phone call to the Dept of Labour and
Industry,
suggesting that this person was running what was effectively :
1) a sweat shop (we were on piece rates)
2) had people working on mains/high voltage equipment without proper
safeguards.
What annoyed me the most was that there was 1 ELCB in the whole
place. Guess who's bench had it. Yep. The boss.
He got a surprise visit the following week from a surly little inspector who
went through the place like a dose of salts. Not sure how much it cost
him in the end, but I know it hurt. I got 4 months back pay and some
public holiday money paid. We got ELCB's for all the work benches and
2 isolated outlets per bench for hot chassis stuff.
(We'd been asking for this for MONTHS, and were always told, nah,
just be careful, you'll be right.)

It sure would not have helped with one of the worst ones I had. 1900Vdc
Electron mult. supply that appeared to have failed (instrument symptoms).
Hooked up meter (rated for 2Kvdc) turned on supply, walked behind instrument
to read meter, it read approx 40V - the way it usually fails. Figured the
supply was dead so why go all the way around the instrument again (40+ foot
obstacle course) to shut off the supply. I went to disconnect probes and
found out the supply was not dead but the meter was dead. Took about 2 days
for the cramps to quit.
Another one - How do you test supplies and various heater controls that have
to float at 8Kv? I.E.: their common point is at 8Kv. Especially when they
are intermittent and you can't tell without the HT on exactly when it is
acting up. VERY carefully float your meter at kV and be very sure you don't
touch the meter and don't do like I did and get to near the leads while
operating the instrument while waiting for the intermittent to act up. An
8Kv @ 5ma with 1ppm stability supply burns holes on the way in and out. In
the arm and out the finger.

They have been somewhat popular over here as translators in the
early 80's - somewhat because the price was at least 50% more
than any other device in this class. It was a try of Nixdorf
to get some hold with consumer products.
No, I found no actual data in our archives, but since this

> A SuperKIM? What's the difference?
The SUPERKIM is a neat little board, based on the KIM
design, but with a real lot of enhancements. It uses
the same 6530-002 and -003 chips to get the KIM software
the same keyboard And connectors. But unlike the KIM
all ICs are on sockets, free sockets are already provided
for 6 more 2114 to get 4 K of RAM (like on the SYM)
four sockets for (E(P))ROM (up to 16 K), four sockets
for 6522 VIAs (one already in place), a interrupt
priotity logic, buffered busses, wire warp connectors
for almost anything, complete memory decode, and last
but not least a huge prototype area and a 5V and 12V
regulator, so you only have to add a transformer, instead
of designing your own PS. And the LEDs are already
atop a seperate PCB (like the keyboard, but here is
no difference to the KIM), so a 'distant' mount of
keyboard and display is easy.
On the backside, the _list_ price of 395 USD was
almost twice the street price of a KIM and in
the same region of the AIM street price (~400 USD
in 1978/9). Shure, for a pure controller system,
you don't need the ASCII keyboard, ASCII display
and printer, but instead more I/O and interrupts,
but the price was still impressive - I don't know
if they sold a lot, but I guess, since the company
had payed advertisements over more then one and a
half year.

Hi,
I picked up a GRiD Model 1900 pen-based DOS machine today. HSC Electronics is selling
them for $20 each here in Californie. I haven't found much in the way of websites,
pictures, etc. of this machine. Does anyone know of any out there?
What I know so far is that they seem to be V20 powered 2 mb RAM based machines with
little expandability but a nice LCD display. It has a semi-standard [compatible but
weird pinout] port for a keyboard. There is a port on the side that I hope is a serial
port and not a CGA or some such thing. How do you get data in and out of these machines?
I was wondering what the little door on the bottom of the machine is. Someone in past
e-mails on the net mentioned that it was for an IDE hard drive connection. Might this be
true?
I haven't powered it up yet as I have yet to order a power supply for it [Monday] but am
intrigued enough to pour a few bucks into it to see if it works properly.
With piqued curiousity,
Thomas

This is very true. In the window of around 75 through now NEC, Hitachi,
Fujitsu, Yamaha and others have produce their own 4bit data path single
chip cpus. NEC had in the early days the uCOM-4 series and later the
uCOM75 series. While each had some similarities to 4004 they were not
compatable. They were also most widely used in games like Einstein,
Simon, VCRs (timer), Microwave ovens to name a few.

OK, point taken. EHT wire is lighter and no more bulky than test lead
wire, though, unless you want to measure currents bigger than about an amp.
FWIW my Fluke only comes out of its rubber holster when I need to change
the batteries (seldom) or the ammeter fuse (far too often!)
Besides, if I can fly all the way from Birmingham UK to San Jose CA with a
Tektronix 4052 (80 lb) in my baggage...
> The most important thing I was trying to point out with the first item in

Agreed 100% (as Tony would say). In the electricity industry, safety
procedures require you to test an EHT meter on a known good source before
_and after_ the measurement. While that's impractical if you're flying
around with no more test equipment than you can fit in a briefcase, a
useful principle to follow.

I agree but that adds weight and bulk to an already overstuffed and heavy
tool / parts case that I will not check through airline baggage. It is
something that I have to do only a couple times a year so I realize I am
taking chances and after the bite of 8Kv I tend to be even more careful. I
have some 40KV rated test lead which would work but it is bulky for use on
the road.
Keep in mind that I used to be in 2 to 4 cities a week. 99% of the time
with airline flights between each city. Weight and bulk is a BIG
consideration then.
The most important thing I was trying to point out with the first item in
that post is NEVER assume the meter is correct. It will bite you.

Now that's VERY interesting, I had no idea such a beast ever existed. I
thought all 6xxx
boxes were XMI/BI. Was it a one off special or something??
I am now seriously contemplating a museum here, mainly the larger stuff,
that home hobbyist users can't readily set up or even store, in most cases.
(It would be difficult to persuade most wives to accept a 6000 and it's
rack of full of RA7x's as a wall ornament)
The smaller Microvax/Vaxstation stuff is more likely to suit hobbyists,
and is less likely to wind up as scrap metal, although we would doubtless
have a suitable selection on display.
Ideally, I would like to make it a working museum, with functional machines,
that would actually be run from time to time.
I hope to get some of the larger PDP & Vaxen and perhaps a Prime and/or
IBM dinosaur or two.
A PDP 11/whatever is on the cards, and I'd like to track down an 8350 or
similar.
If anyone in the list knows of such items coming up for disposal in
Australia,
preferably South Australia or Victoria, I would be pleased to hear from you.
I have a site in mind, used to be a bakery, and has solid concrete floors
and 3 phase.
I am going to approach the owner (friend of mine - I rent a shop from
im - small towns
have their advantages) to see if he is interested in a long term joint
venture.
He's had it on the market for a while and has no show of selling it, so you
never know.

You have a few really neat ones. Some of the big iron vaxen are more
interesting than the smaller. I find the OS, VMS to be most interesting.
I've been acive with VMS since 83 but I was never in the business as
sysmanger... I was supposed to be just a user. I found the machine so
facinating that I took up learning them on my own. The 7 machines are
here in my home, networked and operational. I rarely run all 7 but it's
a matter of hitting the power on any one to bring it up. Terminals
include several VT320s, VT340 and a VT1200.
My wish list... PC emulator that runs on VAX so I can port my DOS/PC apps
to run from the VAXen.

Well, up until recently, that would have been my Computer Room. Over the
last six years or so, we had (all operational) a couple of 11/785s, an
11/780, an 8600, four 8800s and an 8820. Not to mention various MicroVAXes
(II and III), VLCs and 3100s.
Now, the computer room has two 6620s, a 6530, a 6440, 3100/90, a few VLCs
and that's about it (on the VAX side of things, naturally there are plenty
of VMS alpha systems but they're hardly old :-)

My memory may be hazy... and my limited docs are in the crawl space until I
find one of these bad boys for my house.
Most of the KB11A's became KB11D's via an ECO.
I believe this ECO was needed for Unix and some RSX versions.
I believe the 11/70 KB11B's all became KB11C's as well.
There's no difference between the late 11/45's and the rest of the
KB11 line. The KB11A and KB11D were 11/45, 11/50 and 11/55's
and the KB11B and KB11C (and KB11CM) were 11/70's and 11/74 stuff
reconfigured for DEC use as 11/70's internally when they sold AT&T all
their remaining 11/70's for Telco use about 1983 or so.
I thought the difference between the 11/45, 11/50 and 11/55 was the memory
configuration. The 11/55 was semiconductor fastbus memory and the 11/45
was usually an all-core configuration. (Realistically they're
interchangeable... I'd love to see someone make a 128kb bipolar memory
retrofit with a standard 512k cache SIMM for the 11s...)
Imagine ECC and high speed unibus memory... All of RSX or RSTS
living in one memory board.
The 11/50 was MOS memory IIRC.
I believe the MOS and core were about 250ms cycle times...and the
bipolar was half that. (this may be totally wrong... the memory's real
hazy here...)
The fast 32k of bipolar memory in the 11/55 was usually configured to exist
at either the OS memory area (so the OS would be kind of running
out of fast "cache-like" memory or where the main application
lived for number crunching apps. The 11/55, I think, correctly
configured held the DEC speed record on Fortran crunching (faster than
the 11/70 which had a real cache).
The rest of the 11/55 memory was either standard core or mos.

Hello All,
Is there someone who can help me with a copy of the wiring diagram
of the PDP 11/70 console panel?
Thanks,
Ed

Another trick if startup.cmd logs you off the console is when it asks for
the Date and Time do an ^Z
That will exit you out of the startup.cmd (like autoexec.bat) and leave you
at the >(mcr) prompt in SY0:[200,200] then you can continue with Tim's
suggestions.

If you're at the MCR prompt at this point, very likely you've got a
[200,200] UIC. Switch to a priv'd UIC (i.e. SET /UIC=[1,1]), do
a RUN $ACNT, and use the menu options to set the password for the
SYSTEM account to whatever you want.
See chapter 2 of the _System Management Guide_ for more details.
