I haven't seen one of these drives for about 8 years. The company I 
worked for at the time bought them from Arrow Computers in Epsom,
Surrey, England. Telephone number is (44) 372 742557. I would suggest 
that you call them as they should still have the technical details
(which I can't remember, although I believe the emulation was RL02).
Capacity per platter is 20Mbyte. We found these drives to be very
reliable and a very compact alternative to the RL02, particularly as 
it is very easy to back up the fixed platter onto the removable.

Hope the above is useful.
