Could someone please explain the differences between PC's and PS/2's? What processor does a PS/2 use, etc? Thanks, Dan Schikore sks@mentor.cc.purdue.edu

Depending on what model of PS/2, it could be an 8088, 8086, 80286,
80386SX, or 80386DX.
The PS/2 line is IBM's more recent line of computers ... there isn't
really that much of a similarity between the models; it's more of a
marketing ploy than anything. As mentioned above, there is a whole
range of processors available. Some of them are desktop models, while
others are in tower cases to sit on the floor beside your desk. The
lower-end models use the old ISA bus, while models above the 30 and
30/286 use Microchannel. Higher-end models (30/286 and up) have built-in
VGA; the model 30 has MCGA (I think), and I've never met a model 25
(nor do I ever want to).
Come to think of it, though, they all have 3.5" diskette drives
(of different densities, depending on the model number) and 101-key
keyboards (with the possible exception of the aforementioned model 25,
though I think even it has one too). And they're made my that company
with three big blue letters that double the cost of the machine.

Well, I guess Norton's SI must be lying to me when it tells me that >all the PS/2 30s around here have 286s... No, it's not lying. There are two kinds of IBM Model 30's. The regular Model 30 is an 8 Mhz 8086 machine with XT archetecture. There is ALSO a machine called the Model 30-286 which is a 10 Mhz 286 with AT archetecture (as compared to Micro Channel Archetecture). Micro Channel is included on all models of IBM above the model 30-286. You apparently have the 30-286's around there. ============================================================================ Mark W.

Well, I guess Norton's SI must be lying to me when it tells me that >all the PS/2 30s around here have 286s... Now, now, don't be snide. To ensure maximal confusion, IBM has made two different machines, both called PS/2-30, one with an 8086 and the second with an 80286. (The latter has some name like PS/2 model 30-286.) They both have the old AT bus, as does the model 25 which is the same idea as a model 30 but it has a smaller box that includes the display. The PS/2 25 is not a bad deal if you are absolutely sure that is all the computer you need; it's a real PC, unlike the PC Jr. The original PC and PC XT both used 8088s. Now IBM ships nothing slower than an 8086. -- John R.

If you would take a closer look at your model 30's, you will notice that yours are Model 30-286!. The original Model 30, of which I am an unfortunate owner, only came with an 8086.

The original PS/2 Model 30s used the 8086.
The newer PS/2 Model 30/286 uses the 80286.

Models 25 and 30 use the 8086. And yes, I did miss the 80486.

Im not sure this is the right place to post this (is there a comp.sys.ibm.ps2 or a ps2 conference at all?), but here goes: Could someone email me the hardware specs of the ps2. Thanx in advance.
