I don't know if this is of interest to the Big Iron IBM guys, but if
there's any interest from folks not in the Seattle Area, I'm happy
to help faciliate.

That is a 62PC I don't know of any 370 systems that used them, I
think the closed they came to a mainframe was they where used in the
8130 and
8140 systems. There was also at least one in every S/38, in the
later S/38 it was usually only one with the system
microcode on it and it
was
run
isolated from the rest of the disk storage
because of their tendency
to
die
suddenly. I believe that 62PCs where also used
in S/34 and Series/1.

I was going to say it didn't look like any S/370 drive I had seen. Its
also only the Head and Disk assembly (HAD) and if the spindle has been
turned and who wouldn't turn the spindle, its probably toast. It would
make a nice museum exhibit, provided it was donated, but I think $185
is optimistic...]

it's a little hard to come by, hence why I relayed
the find to the list --
just in
case it was worth it.

Jason,
Should have said thanks. It is interesting to see such items, and its also
nice to remember that in the 370 days IBM made many systems, not just 370.
Some of this was fall out from the "abandoned" "Future Systems"
project but
it was also coupled with the Anti-Trust legislation. I was told by an IBM'er
that IBM was
Worried it would be split in two, and as such had engineered the product
line such that in this event, both halves would have kit to sell that they
could make themselves.
So while System/3 and System/36 could use some S/370 peripherals they had a
complete range of different devices, such as twin-ax terminals. Weird...
In the event it didn't happen and IBM was left with multiple incompatible
designs...
