Hi list,
Just came across this:
https://www.ebay.com/itm/Vintage-Computing-CDC-Magnetic-Peripherals-Control…
Haven't seen one listed in years. The price lets me assume that this offer addresses
customers that may use these drives in a production environment or so...
I am not aware of museums or hobbyists who have such drives currently in a functional
state to read and write from and to 80MB (CDC 9762) or 300MB (CDC 9766) disk packs. Maybe
the CHM? ... not taking into consideration the CHM activities related to the Xerox disk
cartidge? (2315-equivalent) software archive project.
Anybody out there? Would be interesting to know.
Best regards,
Pierre

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

When I was there for VCFPNW, I saw the rig they'd built for that. At the
time they were perfecting getting photos of the surface taken and were
looking into writing software that would convert the images to a data
stream.

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. It might take a while to find them in my
mess, however.

Interesting, I've just picked up two 9766s and two OEMed CDC pack drives
(unsure of model # yet). I might be bugging you about spares :P
Thanks,

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?

Would this have been connected to a CDC Cyber back in the day? I noticed
that this is in Athens, GA, home of University of Georgia. The first
programs that I ever wrote were on a CDC Cyber there (via a 300-baud
acoustic coupler modem at Valdosta State College).

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.

It was an uncommon option for lower end Cyber 180s.

Don't know the date of the unit shown, but in the early-mid 1970s, we
used acres of 844-21(IIRC ~100MB) and 844-41 drives (IIRC ~200MB).
Don't know what the OEM model would have been. And Cyber 180 is outside
of my timeframe.
..and they were damned twitchy if you were unfortunate enough to mount a
damaged pack.

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...

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.
Thanks,
