I don't have the receipt for this one, but it was bought about a year earlier. Single speed, it said, although it couldn't actually keep up with 150k bytes per second – its real speed was about 75k/s.

About the size of a hi-fi CD player, it needed an interface card to talk to the PC. You had to put the actual disk in a caddy before you could insert it – none of those trays or disk slots here! It came with an encycopaedia, Groliers, and a disk of share/freeware.
