Does anyone recognise the make/model of this removable hard disk pack?

it will be 1980s era and looks to be around 8" or so

Now that's interesting. I've never seen one of them before! It's also not listed in the museum of obsolete media either: http://obsoletemedia.org/

Blue says 1990s to me.

Interested to see if you find an answer to this.

You can rule out DEC if that's any help. It's Blue, but I doubt it's 'Big Blue'.

Possibly one of the smaller players - Data General, Wang?

You bring me back beautiful memories. I worked in the eighties as service engineer for a DEC representative, some of our customers had those drives and also the fixed disk version 9715. Those CDC drives had SMD interface an where attached to PDP-11 Minicomputers using controllers from Emulex. I have even the drive boards repaired, they had TTL and ECL logic.

yea, sounds about right!

the disk pack in the photos i posted was used on a quantel paintbox, specifically the 'classic' model, we believe it contains graphics from the cartoon network in the mid 1980s.

It would be an interesting archeology project to extract the data. Finding a drive mechanism could be a real challenge though, a lot of equipment like that is simply extinct.

Looks like a Lark pack. I used to use those in the mid-1980's. 25MB on the removable pack.
However they were also notorious for spin-up head crashes, where the heads were slammed into the side of the pack with total destruction of both.
Was it really supposed to do that?
