I'm beginning to write a driver for a mini-cartridge tape drive that uses a floppy compatible interface (WD1793 floppy controller chip). By mini-cartridge, I mean the 3M DC 1000 type (real small). The drive, from Irwin Magnetics, will store 10.35 MB per tape. I'm interested in communicating with people who have done this in the past, as I'm not too experienced in extremely low-level device drivers that deal in counting pulses, etc. What's the best way to vector to a different driver given that the interrupt could come from the floppy or the tape? What's the best way to handle both streaming and start-stop mode? Etc. As always, I will summarize and post if there is sufficient interest. David Hinnant SCI Systems ...decvax!mcnc!rti-sel!scirtp!dfh
