 sort.  I think they measured...2.75" (?) and held...not much at all. 
 was that a 2.8" diskette with a single continuous spiral track? 
That's it exactly.  It was the Akai S612 - or more specifically, the Akai
MD280 external disk drive.  IIRC the sampler could be bought without the
drive, and either send and receive samples over sysex or from tape.  I
*think* it had 48k of memory.
I passed up the chance to buy one, with the drive and a large library of
disks, for 50 quid in a music shop in Inverness a few years ago.  Oh well.
