One of you thinks the 8530 (PS/2 model 30) was an 8088, the other thinks it
was an 80286. I claim you're both wrong. The model 30 was IBM's first
(and to my knowledge only) machine to be based on the 8086.
If I am wrong, and a 286 version did exist, no doubt flames will appear in
great numbers.

8088 or 8086, same basic difference in that it's an XT class machine with 8 bit
slots You can read the specs on the model 30 at
http://www.can.ibm.com/helpware/8530.html
There is indeed trillions of model 30-286 units out and about, one being where
I work on the network tied to an AS/400 as a disk type workstation. The specs
for it are at http://www.can.ibm.com/helpware/8530286.html
There was also a model 25 and a 25-286. Both ISA machines.
No need for flames, yet. <g>

IBM did produce model 25-286 and 30-286, in fact around '90 I was
using this 30-286 doing CAD course in high school.
The motherboard is exhangeable between 25 and 30 chassis and there
was 2 ways: IBM way by special 44pin drive directly plugged into
motherboard itself by ribbon or use MFM or SCSI on ISA slot.
Oh, there was some 386sx version made for that case.
Haven't seen this one and what was right model # for this?

I'm not too sure of that due to the sizes, but you may be right. The FRU numbers are
different
though.

The 386SX version of the 30 took one form in mca, the 55SX. Not sure which model (33?) was
equal
to it in ISA.

The original Model 30 was, in fact, an 8086, but I think I might dispute the
"only" part since I assumed that the Model 25 was also an 8086.
There was also, however, a 286 version of the Model 30 which came out a
little later. (I'll let the IBM experts come up with the model#.) IIRC,
the press at the time called it "The PC/AT Reborn".

The models up to (but not including) the 50 series were ISA and after that were
microchannel. The 25 came out originally as an XT class machine with an 8086
processor ( see http://www.can.ibm.com/helpware/8525.html ) and the 286 version of
it was only one version that I'm aware of as seen at
http://www.can.ibm.com/helpware/8525286.html
The LS may be an aftermarket version, much like putting a Reply motherboard into
one.

Oh, the collectibility of MCA machines was brought up once before in this
thread, and (to me, anyway) the Tandy MC5000 seems rather collectible, as
one of the very few non-IBM MCA architecture machines ever sold. (I
acutally saw one, once upon a time... they weren't too popular, tho.)
Was this the first MCA "clone"?
I'm pretty sure the MC5000 came out in '88, so it's ontrack topically.

Hey! I'm not Canadian, and I say eh! (of course, the border is roughly 4 km

Don't recall the precise release date, but they were definitely out
when I attended the Tangent (Tandy Professional Users Group)
conference in Fort Worth in 1987.
Not exactly a "clone". The MCA architecture was fully licensed and
paid for by Tandy to IBM. The 5000MC actually had a better MCA
implementation than the IBM systems at that point, as Tandy didn't
cripple the bus-mastering feature the way IBM did. Naturally the
machine died like a pig, leaving less of a ripple as it sank than
the Tandy 2000 or even the Tandy 600 portable had.

I checked my '87 computer catalog (it's here at work) and it wasn't in
there. My '88 is at home, so it's prolly in there.

Yes... and ISTR that IBM wanted a small fortune for that license as well.
Prolly one of the reasons it never caught on; very little profit to be made
as people weren't willing to shell out the big bucks for a system, and all
new cards as well (MCA stuff commanded quite a premium back then).
The 5000MC actually had a better MCA
implementation than the IBM systems at that point, as Tandy didn't
cripple the bus-mastering feature the way IBM did.
That I didn't know, as my main (work) machine was a CoCo3 until I needed
Autocad capability and my (then) employer loaned me a 486DX2/66 (which ran
the CoCo2 emulator pretty well...)
The CoCo3 is still set up next to "Goon" which is a Pentium II 350 (dual
capable) w/256Meg ram... and no, I've been too busy to try the CoCo 3
emulator on it... but in a couple weeks I should have time. I wrote a
(very, very) basic benchmark proggie in assembly... my Cyrix 150+ was
roughly an 8Mhz CoCo3. I'll let you know what my Pentium II runs like... if
my proggie doesn't need to be recoded.
Naturally the
machine died like a pig, leaving less of a ripple as it sank than
the Tandy 2000 or even the Tandy 600 portable had.
Too bad... the machine had potential. I remember seeing "MC5000" thinking
"yea, that's prolly the price..." Lo and behold: $4999! ( I think that was
it's initial roll-out price)
Anywho, enough rambling, & back to work.
