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...

Dave

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

days of

S/38 it was usually only one with the system microcode on it and it was

isolated from the rest of the disk storage because of their tendency to

suddenly.  I believe that 62PCs where also used in S/34 and Series/1.

Paul.

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...]

Interesting.  I know nothing about older IBM stuff other than people say 
that it's a little hard to come by, hence why I relayed the find to the 
list -- just in case it was worth it.
