A friend found this strange disk drive on the flea market. He bought it because the interface said "MSX" and because it looked like a 3,5" drive, but when he came home no disk would fit. So it's either a 3" or 2,8" drive, or something even more obscure.
There are no hints as to the producer on the drive or its interface, but it says "QD" on the front. On the back is a compartment for a set of batteries, which seems to be the only power source you can use.
Have you seen it before?
woooooooooooooooooo
OOOOOWWWWWW!!!
so, it is like a cassette-deck recorder, but with its own controller and ROMs....!
I imagine basic's commands like.
BLOAD"DQ:",R
instead of:
BLOAD"CAS:",R
Is there a manual!?
And shit!, why the hell it has a battery compartiment.... It can use easily the PSU of the MSX available at the msx BUS....!!!!!
No, unfortunately it works with commands like:
CALL QDFORMAT
CALL QDLOAD
CALL QDFILES
etc.
(I might remember the command names wrong...)
64KB / side, then you need to flip the disk over. 
Loding always takes about 5 seconds... No matter how much data you load... Funny device.
...with sequential access, if you want to delete the last file on the disk, you must delete first the previous files
