1987 PS/2 Monitor Specs?

I bought a complete IBM PS/2 Model 50 system back in the fall of
1987. I still have the system, but threw away the monitor years ago
after it lost focus and failed. Now I'm trying to remember which
monitor model I originally had with this system. Can anyone help me
remember which it was?

I believe that it was either a 8512 or 8513. (I know that it was
NOT the 8514 14" monitor, which may not even have been on sale at
the time).

My recollection is that there were two color VGA monitors from the
PS/2 series that IBM sold in 1987 for the typical Model 30 and Model
50 systems. One monitor was slightly larger and had a larger (i.e.
inferior) dot pitch. The other monitor was smaller (12" I believe)
but had a better dot pitch, sharper image, and came with an
adjustable monitor stand. I had the "better" monitor, which I
believe was the smaller of the two. I do remember for sure that I
bought the more expensive of the two. Now I can't remember which
model number it was.

As I said, I kept the entire system (documentation, boxes, etc) but
no longer have the monitor. It was first replaced under extended
recall warranty (although my particular unit had not yet lost focus,
IBM identified premature failure and allowed swapping out
replacements for free). Several years after that the replacement
monitor completely lost focus and I disposed of it. (This was in
the mid-1990s).

Does anyone have the specs for the standard IBM PS/2 color VGA
monitors sold in 1987?

Thanks!

The model 50 complete system that I had (second-hand from original
owner) came originally with an 8513.

Louis has kindly provided the specifications for the 8512 and 8513.
In case it is not obvious from the specs, the smaller 8513 monitor is
the one with the nice, crisp display and the 8512 is the one that
"looked like crap" even when new. If you decided to go monochrome
instead of color, either the 8503 or 8504 is a reasonable choice. On
the color side, the 8511 is another lousy-looking display, but the
8515, 8516 and 8518 are all good choices. The 8515 and 8516 can do
1024x768 like the 8514, but are physically about the same size as the
8512, the 8518 can only do 640x480 like the 8511/12/13.

If you decide to go for "newer" IBM VGA monitors than the 85xx series,
the choices really open up -- there's the Valuepoint displays in the
63xx type numbers, then there's the 95xx type number range of monitors
(the "Premier" displays) and the 65xx "General" (G40, G50, G70, G200,
etc) and "Premium" displays (P50, P70, P200, etc). Some of those
models have touch screens, too.

The display on my primary home system is a P260 (6552-63N), which is a
beautiful Trinitron CRT with an "almost flat" front running at
1600x1200. It's very nice, but it takes up a lot of space, is a bit
power-hungry, and is *heavy*. But I got it and it's two "brothers"
for free, so I can't complain.

Definitely 8513, a 12" display with a dot pitch of 0.28 mm. I burned after a
few months one, IBM replaced it and I still have it. The monitor was
introduced Apr 1987 and manufactured for IBM in several different countries.

Indeed....and as we old pilots learned in training, as you go higher,
the temperature decreases at a rate of about 2 degrees celsius per
1000 feet. By this time you have frozen some pretty important body
parts.........

Hi!

> Can anyone help me remember which it was?

From what you have said, it seems like you had an 8513. That would have been
the smaller display (ironically enough, considering the model number) but it
had better specs all the way around. The 8512 was the cheapest 14" VGA color
display IBM sold with the PS/2. (Someone can correct me if I'm wrong.)

There are three 8513 strains I know of: ones made in the US, Taiwan and
Korea. Of those, I've seen about an equal mix of US and Taiwan units. Only
one Korean made unit has ever darkened my door. The US made ones were built
by IBM, and had a Panasonic tube. Units made in Taiwan were assembled by
Tatung and I saw mostly Toshiba tubes in those. I don't know about the units
made in Korea--possibly Samsung?

Reliability wise, and measuring by personal experience, it seems like the
US-made ones were the best. I almost never found one of those dead. The
Taiwanese made units seemed to have a lot of trouble with focus loss, color
shifts or even bad caps. The lone Korean unit I saw did nothing except try
to degauss itself when powered on.

I only have two left now--one made in the US and the other in Taiwan. The US
made one seems to be suffering from power supply instability, especially
when warm. The Taiwanese-made unit has lost a lot of focus and
brightness--I'd imagine the tube to be worn out.

There is another, more sinister aspect to the USA-made variant of the 8513.
Unlike the Korean and Taiwanese sourced units, the US-made model is held
together by some snaps instead of screws. These are somewhat difficult to
release. IBM made a tool for doing the job, but I've never seen it.

There is so little room around the tube neck in the case that if you get a
little too ambitious, you will *break* the CRT neck clean off. i know. I
did. In my case I heard a "hisssssss" and that was it, but the tube could
always implode and that may happen violently.

The "tool" is a simple piece of plastic of an appropriate length,
ending in a taper so that it will lift the latches when inserted into
the slots in the back of the case. If you had the dimensions, so
could make your own out of heavy cardboard (you can use the size of
the slots as a guide, as I recall the length was around 6 inches).

The higher up you go the thinner the air is, which affects heat conduction

Actually, my question was purely rhetorical, and meant to provoke
hilariously funny responses. But, if you prefer seriousness:

Assuming you were actually watching your CRT at or above 2134 meters, I
would have to assume that you were enclosed in an environment conducive to
human survival. This would probably be temperature controlled, which would
negate any altitude induced freezing, or severe changes in heating or
cooling, as I would imagine this is necessary for most human survival, or at
least comfort. However, if you were truly an outdoorsman type, and insisted
on climbing for example Mt. Everest with your handy dandy pup tent, and a
really long extension cord for your PS/2 computer equipment, possibly even a
CATV cable for internet access, I could see this being a problem for the
equipment working properly.

No, I was more concerned with the difference in atmospheric pressure.
Assuming a standard 14.7 PSI at sea level on this planet ( which the monitor
was designed for ), I could certainly see a problem at high altitudes. The
atmo pressure against the screen/glass would be reduced. The cathode would
send streams of electrons to the anode, accelerating them into the
phosphorescent screen/mask, and blow right on through the screen because the
pressure holding the glass is reduced, causing deadly glass shards to be
blown all over the pup tent. With a color monitor, and three "guns" blowing
electrons everywhere, the problem would be even worse. This would of course
result in major disruption of internet service, and probably cause
irritation to a person sitting in front of the monitor.

That would be my primary concern, reduced pressure against the glass,
allowing dangerous and deadly electrons to explode the screen with great
force.

Just my 7� worth.

Ah, well, understandable. After all, you were "high" for 5 straight years.
:-)

Never having experienced being at great height myself, I have heard that the
memory is dodgy at best under
such circumstances.

quite right, my statement is missing, actually that event happened
sometimes 17+ years ago, between 1987-1993 :-), took almost 2 weeks for
my body to adjust to the hight, 1 st day was the worst.

I must have had the US-made model, because I clearly remember
finding that some strange snaps were required. No way to open the

My 8513 had a great "feature" where after a few weeks of use (several hours
a day), if I put my hand up against the center of the CRT I would get an
ENORMOUS shock of static electricity. I mean, I'd be seeing stars and
everything. I wouldn't even have to touch the screen - as long as I got
1cm from it I'd get knocked on my rear. I could never figure out if this
was a hardware fault or if I just literally was building up that much
static electricity, although I've never experienced that with anything
else. This "feature" started in late 1988 so the monitor was only a year
old. It didn't matter if the screen was on or off....

iirc? I don't remember the S/N prefix that was affected (23- or 72-)

A 23- serial number prefix indicates a "made in the US" IBM product. A
prefix of 55 indicates Europe (Greenock?) as the place of manufacture,
and 72 means Taiwan (and possibly Korea as well).

All of this is open to correction, my memory could be fuzzy about the
exact meaning of each prefix.

Anyway, I have heard of that recall. I don't know what variations of
the 8513 it affected. For all I know, IBM could well have treated all
the various 8513 types equally. It was supposed to have something to
do with focus failure.

It would surprise me if any monitors covered by the recall were not
replaced very soon afterwards. Today it seems like most of these
monitors are just reaching the limits of their lifespan.

Wow. My experience (yours could vary) suggests that at least the face
of a computer CRT is grounded. It seems like you could have had a
charge built up by the time you arrived.

Unless you'd been going out of your way, though, I wouldn't expect
that such a shock would do any more than give you a little surprise.
Maybe something was wrong with the monitor's internal wiring,
something plugged into the same circuit or the building wiring?
