I recently got hold of a diskdrive:
Amcodyne Model 7110
A controllerboard for a DEC PDP Qbus is included. The drive seems to have
2 platters, 1 removable and 1 fixed. Formfactor is something like 8", capacity
something like 20Mb/platter
What I would like to know:
- Actual drive parameters: #of cyl, sect/track, seek time, interface type
etc etc
- What DEC drive does this disk emulate (RSX11M seems to understand it)
Any info is appreciated

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.
