To: all

The company I work for is in the midst of designing some new 6809 hardware. The
new board will have a 3 Mhz 6809 (6309? The one by Hitachi), a megabyte of
(paged) RAM, a DMA chip, a floppy disk controller chip of some type (probably
an Intel family part) and a 1.44 MB 3.5 inch floppy disk drive. We are going to
use the MESS-DOS disk format so our customers (who probably already have a PC)
can configure our unit off-line, duplicate disks, etc. I get to write the
floppy disk code which leads me to my questions:

Would a driver written in C be fast enough?  Is anyone aware of any C source
(licensable or PD) for dealing with the MS-DOS disk format?

If assembler is the way to go, are there any example '09 (or C) floppy drivers
available here or elsewhere that someone could point me towards?

Any sources of information, references, hints, etc., would be greatly
appreciated.

Thanks in advance,

-J
