I saw an IBM 5150 today in a thrift store. The odd thing about it was
that it had no disk drives! It only had two black covers over the disk
drive bays. It seems like it came from the factory this way. It is the
first revision of motherboard with the cassette jack, so its conceivable
that it was used with a cassette recorder and was always like this. Does
anyone wish to concur on this? I'm debating if I should get it, but not
for the $20 they have it tagged for.

My understanding is that some of the very first 5150s did ship with no
floppy drives, but IBM rapidly found out that people preferred the floppy
drives. My guess is that it probably has a low serial number and most
likely has the 16-64K motherboard. I would put it in the rare classification
(assuming it came that way from IBM.)

There wasa also a 5162 PC. We've got a couple of them. Does anyone know
how they were set up? full height or half height floppies? Any hard drives?

That one set me searching my books and files.
It's an XT 286 Scott Mueller's book has full system architecture specs.
80286 cpu at 6mhz w/0 wait states
640k mem
1.2M 1/2 ht fdd and 20m hdd came standard but it will
support an additional 1/2 ht. Either 5 1/4, or 3 1/2
720/1440.
Damn ! Another to add to my "stuff"
To Tony's list could also be added
3270 PC an XT with 3270 connectivity
5279 ? it's monitor (have one but it's buried)
XT 370 giving connectivity to and emulation of the S/370
AT 3270 like the XT model but based on an AT

5145 PC Convertable colour monitor

I believe we have one 5160 with full height drives, and one with half
height. I don't think either boots properly. Now at least we can get
them cosmetically cleaned up. As I recall they both seem to poll both
drives at once, or something weird like that. Shortly after I looked at
them, we lost power due to renovations, and that was 18 months ago. I'll
have to start all over again.

Yes. I have a 5160 in front of me here with official IBM-badged drives
that I believe to be original. And a couple more similar machines upstairs.
All are full-height Tandon mechanisms.

Check the DS jumpers and the cable. Sounds like the controller thinks both are
A:, or the cable is reversed. The end with the "twists" (pins 10-16 I think)
should be on the A: drive, not on the controller. I've found a few "bad"
machines
that supposed experts have worked on done in reverse. Also a foam swab and
denatured alcohol on the heads cleans them up rather well.

Early 5160 XT's used the fulls, then they came out with direct drive (as
opposed to belt drive) half height drives and a blanker that filled in the
empty spot in case you didn't use 2 floppies in that bay.
I had a 5160 with 2 factory full height drives around, may still.

No, The PC and XT both came with FH drives. The XT also came with a FH hard

There were variants all over. I have one that is shipping soon that has a
Seagate ST-225 (half high) but has a full height faceplate, with IBM molded
into it. I've also had XT's with factory HH floppies. Either you had a stack of
2 ith a trim ring, or one with a lower blanking bay and trim ring. Many of the
ones with HH units seem to be the later part of production though.
RTC's usually came on aftermarket cards on PC and XT machines, even on the
Sanyo MBC-55x series. No need to add a battery if there was no need to backup
setup info, right? Sell 'em another expensive board right? That's the ticket,
and they'll believe that we're doing it all for them. I still say that someone
created this modular thing as a convenience, and then used it to slowly drain
you.

I think this was the first IBM product to use SIMMs, but I could be wrong.
The rumor was that IBM had a bunch of left-over parts, including 8MHz 80286s
and XT cases, so they decided to patch together a machine that would use the
parts. The 5162 also supported 720K and 1.44MB floppies, but a kludge is
required to poke the 1.44 diskette type into the CMOS cuz the AT diag
software doesn't support it.
Most of the 5162s went to IBMers and we still get calls from retired IBMers who
are looking for software or want to fix them up and give them to family
members.
There wasa also a 5162 PC. We've got a couple of them. Does anyone know
how they were set up? full height or half height floppies? Any hard drives?
IIRC the 5162 is the XT model 286. It's a 286 motherboard built to fit
into an XT case (and remarkably similar electrically to the PC/AT board).
IIRC it was the only IBM PC (as opposed to PS/2) to use SIMMs.
The standard drives IIRC were a half-height 1.2Mbyte floppy in the left
bay and a 20Mbyte full-height ST506 drive in the right bay. The
controller was the later (not so tall) version of the AT controller.

Santa Barbara selling a bunch of older computer magazines, hardware,

with the guy tonight and he is the person I thought was selling the stuff.
He is moving to Arizona in a month or so, and that is the main reason he is
selling off all this stuff. He still has quite a bit left, so I am just

Well, don't expect to get any real good deals. He found ebay and now is
demanding at least ebay prices, or else he deems your offers "a joke".
He'd rather sell and ship onesies and twosies than sell whole lots at a
time for reasonable offers.
He can kiss my sweet young ass. ;)
