Is there a brand name? (Somebody else might HAVE one)
Otherwise,the drive is almost certainly not a problem, and you can
probably use an "industry standard" drive, such as a TM100-2.
But you will need a controller that can handle hard sectored diskettes.
Depending on the specs of the format (which you haven't tod us), it MIGHT
be readable with Northstar hardware, or it MIGHT be readable with Vector
Graphic hardware, etc.
OR, you could build an appropriate controller for a PC.
