Most powerful PS/2
Jerry Abrams
was the model # of the most powerful PS/2 (microchannel) machine? Was
it one of the 77 models that contained the 486 DX/2 66 MHz.

'official' IBM component, therefore making it the fastest PS/2
configuration. The IBM PC Server 500 would be the fastest pure MCA x86
machine (it came with a type-4), with the PC Server 720 being the fastest
x86 MCA machine (though not classified as PS/2s). I guess some form of
RS/6000 would be the fastest machine with MCA, but that's not x86 or related
with PS/2s.

P6x were for the 95A. P90 came later with the S500 as I understand it.

I have a 9595-0QT, which came stock with a Pentium 66 complex and (FDIV)
CPU.

The 77 models included the latest PS/2 designs, but I don't think
"powerful" was the primary design objective for that model.
The late model 95's (such as 9595-3QT) are far more powerful than any
model 77, with the most advanced CPU's, highest capacity primary and
secondary storage, and most "powerful" power supplies of any
microchannel PS/2. Some even came with Fast SCSI hardware RAID setups.
I have never experienced "Passplay" RAID in a 95, but can tell you that
"Cheetah" F/W Streaming SCSI RAID 0 in the similar microchannel PC
Server 500 offers amazing performance.
But were the type 4 95's PS/2's? IBM's web site seems to distinguish
them as "PC Server 95". IBM Canada also calls them "Server 95", but
includes them under the heading "The Personal System/2 (PS/2)
products". In any case, I think even the DX-50 equipped PS/2 95 XP 486
(9595-0MT) is more powerful than any 77 (Synchrostream notwithstanding).
Hmmm... your rules say before *non-IBM* motherboard/processor
replacements". The PS/2 95 XP will take a type 4 processor board as a
drop in replacement. Can we also cut a little hole in the back of the
case to fit a Server 95 "motherboard"? :-)

Whoever wrote that was wrong. The official name is "PS/2 Server 95".
AFAIK, the PC Server line begins counting from 310, i.e. "PC Server 310",
to suggest - in my interpretation - PS/3 or PC/3.
In the first PS/2 generation, the most powerful models were the A series,
mod. 70 and 80, with 25Mhz 386 and 64K cache. Mod. 70-R21 and the Power
Platform increased that to 486DX2-50. Later, processor upgrades became
available.
The second generation targeted 486 and early Pentiums. Most powerful desktop
models were 486DX2-66, e.g. mod. 77, and Pentiums were reserved for the
servers, e.g. mod. 95.
"Most powerful" leaves room for interpretations, I consider here the only
CPU and commonly available models.

There was a PC Server 300 as well, it may have came out at the same
time as the 310. (I don't really remember)
It was, however, a total piece of junk. Think of a 320 case with a crappy
486 ISA MB thrown in. There may have been a P60 version later on
as well. Best forgotten, no MCA variant, short lifespan...

You are right. I dug out the "Personal System/2 System Library" that
came with my 9595-0QT. On page 1 of "Setup" it says, "Welcome and thank
you for selecting an IBM Personal System/2 Server 95". Then on page 5
is a picture of the type 4 system board with dual parallel and dual
serial ports.

I believe the pc server 300 is an eisa based machine, got one upgraded to p66
runs win 95 real good.

version of a p60 9595 model. Not nearly as fun as the equivalent PS/2 models.

why is everybody speaking bad in the S300?
Its a nice machine, PCI/EISA based withe P60/66
(maybe there was a 486 version as well)
I got one running NT4s with an DPT smartcache III
EISA RAID5 and a DIGIPORT EM multi serial board.
Yes, it has no MCA at all, not even parly PS/2 components,
but there should be a little more tolerance!

Yeehaw! Fortunately I'm not the only one that tends to use EISA based
machines.
There is also another small thing to consider. Never mind how advanced the
MCA was for its time, it simply did not catch on everywhere. Even after
serious rummaging at the recyclers and used computer dealers here in
Scandinavia, I have managed to unearth only a handful of mca boxes. Out of
those only one has been anything bigger than 286. Sad. The bigger, younger
models seem to be EISA.

EI ScandinaviA .... Perhaps EISA machines generated more heat in the
wintertime.

The PS/2 badge is reliable and trustable. The official name is inscribed on
it.

outperform the straight ISA and can even give PCI a run for its money. Both
also seem to have the same kind of problems when trying to find the correct
adf/cnf files not to mention the setup disk in the first place.
Let's keep on hacking the iron that we have.
I will go and fire up a couple more EISA boxes, it is getting cold here.

P90's were available as original equipment in euroland.

Yes, I have one. 8640-0NJ is my type-model. Mistook it for a 320 when I got,
came to realize slowly that it wasn't.
> It was, however, a total piece of junk.
I don't agree...bought mine for $25 to replace an ailing (and much more
powerful when it worked) file server on my personal network. That was three
years ago and the machine has not been turned off for maybe more than an
hour or two during that time...for cleaning, upgrades, etc...
All that time it has run absolutely reliably--even now when fitted with a
POD83 upgrade CPU there are no problems.
No, it's not an IBM board, but it's not some unnamed "chop-suey" speciality
either...Micronics M4PE IIRC. I don't know about no MCA variant--mine's
PCI/EISA for certain but I heard Micronics also made the M54PE board as seen
in some 320 as well.

Best things about EISA:
* you can insert an ISA card in the slot and go
* you can use ISA modems, sound and scanner cards
* EISA Busmaster SCSI can be very quick
* Adaptec has EISA support even for OS/2 1.3.
* Some boards have processor cards just like the PS/2 processor complex
Although boards and cards are pretty good, different manufacturers don't
give the same attention to details. My EISA box is a pretty solid box, you
can install two hard disks and still have three full-height free bays.

Good idea, the same here. But where did I put my EISA box ?

Lower standard of living and heating ... The country is rich, we are poor
and the winter looks like coming early and staying for longer? No, no room
due to the PS/2 invasion, books and stacks of magazines, lately the nearly
complete series of "Electronics" from 1953-57. Good heating stuff (horror!)
if they weren't awfully interesting. The latest news on magnetic core memory
and tape drives.

So its time to open my ALR Revolution Pro (EISA/PCI) and replace the 486
DX2/66 CPU complex with the dual P90 one I have somewhere.
Or try to get Debian Linux working on my dual P166 Server 320 (EISA/PCI
too) with the Mylex Dac960P controller.
Or better replace the dead harddisc in my 8595 and let Debian run again
on that nice machine and heat up my rooms?
Long cold winter is coming and all that machines convert a lot of
electric power to heat ;-)
