I'm not positive what pack washing machines used. Distilled water seems plausible, perhaps with some sort of mild cleaner. Keep in mind I'm talking about packs, no electronics there. Then again, many electronics are designed to be washed in water (as part of the manufacturing process).

I have some submerged packs that look like the one in the auction. Wet since Saturday :-( Here's a link to the drive that I'd like to restore some day: http://www.digitalheritage.de/peripherals/cdc/854/854.htm I think I have the same :-) And I have cables and lots of spare heads: All

I am looking for someone who can read an ICL EDS8 disk pack. I am told that it would have been used in an ICT type 2802/2 drive on an ICL 1905E, but that it is also compatible with an IBM 2311 disk drive and that it uses a mechanical assembly based on a CDC 9450. Given the mention of the 2311

Anybody has Control Data (CDC) disk packs for 841 and 844 disk drives to spare with?

Hello everybody, recently, there was an US epay auction with a CDC 849 disk pack. http://www.ebay.com/itm/292129988099 This pack is for the early CDC 851/852 disk storage drives and thus not of interest for me, as the packs I am looking for my 854 drive have a different amount of sectors
