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

I moved a system with 4 300mb memorex 10 (or so) platter drives eons 
ago, which had been running for a year or more.  After setup and service 
it ran 2 hours before eating one of the drives.  That was and is the 
last time I'll ever run drives w/o sealed HDAs.

Hate so much of the old stuff we mess with needs removable platter 
drives to run.  Had no patience then, even less now.

I'll take emulated drives or whatever attached to the artifact systems 
any time, vs. running original disks subsystems.  It's good that the 
work to get the replacements going is being done now while the people 
still familiar with the OSs are still around or people who can do that, 
as of course doing it later if one wants to restore and run systems like 
that further down the road will make it much harder to do.
