RE: Model 40S DASD -- 6502 IOP

["Carl Galgano" <cgalgano2@xxxxxxxxxxxxxxxxx>]

6607 from any system will work.  The problem is in the carriers.  But since
you already have the system packed with 2GB, you should have all the
carriers you need.  Come to think of it, the 40S has rails, and not the
carriers like the 5xx, 6xx and 7xx system.  I have 10 6607s in a model 400
that is still running V3R7.  They run just fine.

Tom,

> Does anyone out there know what a 6502 in a 40S can handle?

Originally, it was only up to the 2GB drives.  At some release (but I don't
recall whether V4Rx or V5R1), it could take the 4GB drives for sure.  I also
have a 40S with the 7117 expansion, and I have it fully populated with 6607
(4GB) drives except for the load source which I left mirrored on a pair of
6606's.

I don't know if support for the 8GB drives was every added, but can confirm
that 6607 drives work nicely.  And don't develop stiction near as often.  I
had replaced serveral 6606's while I ran them; I have yet to have a 6607
fail on me.

>The used-equipment market can supply plenty of cheap replacements --
when part numbers are right.

I think you can get by with any of the 6607's.  Many of mine came in the
cages used on larger systems, and I just removed them and installed the
rails from my 6606 drives.

If you need any bare drive 6606's, I still have a stack of them left on the
shelf...  :)
