Being SMD, they could be connected to a number of things. PDP-11s, as mentioned, as well as basically anything that talked SMD. Mine were hooked up to Data General and Computer Automation gear.

RE: Control Data 9766 drive on epay
Pierre, I would suggest that as you haven't seen one in ages, the price reflects the rarity and the vendor is hoping for a rich collector to buy it. I don't know off hand of anyone who uses one. I know that the 4341 at LCM uses emulated DASD as does the ICL 2900 at TNMOC in the UK which I think has some EDS300 drives https://farm9.static.flickr.com/8314/7939054098_08c37818fe_b.jpg which look almost identical to the CDC drive on E-Bay, there are a few more pics here https://hiveminer.com/Tags/bletchleypark%2Cicl There are people using smaller exchangeable drives such as DEC RL01 and RL02 drives, and the similar drives on the IBM1130 and IBM1800 but those are a totally different ball game...

I am not a CDC CPU expert but I know that various CDC SMD drives, especially the 9762 and 9766 were found on PDP-11s and VAXen owing to inexpensive (compared to DEC) 3rd Party disk controllers (and drivers for various operating systems). The drive mechs were also repackaged and put behind modified SMD-Massbus interfaces and were available from DEC as the RM02/RM03 (9762) and RM05 (9766) but they were DEC badged not CDC badged (colors, labels, etc) so you wouldn't mistake one from the other externally. I happen to have a 9766 (and at least one SMD interface for either Unibus or Qbus) but no pack. -ethan

Re: Control Data 9766 drive on epay
Well, crap. I got rid of my 2 9766’s and all the packs that I had for them a couple of years ago for nothing what this guy is asking for his. ;-) I probably still have a pile of heads for them (but they’d probably go to the guy who purchased the drives/packs from me). What are folks using these types of drivers for? Media content recovery or just using them as intended?

Interesting, I've just picked up two 9766s and two OEMed CDC pack drives (unsure of model # yet).

There is a Make Offer option, and it does look like the seller does take offers fairly regularly. I will not be buying it. If someone does, I have a huge amount of spares for 976x drives, including refurbished heads.

Maybe the CHM? We don't have one in working condition, and we're unlikely to attempt any work on multi-platter media recovery any time soon. I have three Pertec top-loading drives and several Diablo 30s, but haven't had time to try flux-level recovery on several dozen high archival value targets, including what may be the only surviving Burroughs B1700 packs. LCM was working on an alternative approach to multi-platter media recovery but I've not heard anything more about that in a while
