Have you interfaced a SCSI chip? I would like to interface a Single chip MCU to
a SCSI hard drive. To save on $$ I would like to *not* use a SCSI controller
chip in the commercial design. Is this practical? Can SCSI work in an
asynchronous mode? Where can I find a *simple* explanation of the SCSI
interface? If I must use a SCSI controller chip, what chip would you suggest?
Where can I get a cheap chip, and do you have any source code which shows the
sequence of commands to read/write/format etc...

I would also be interested in any info on other Drive interfaces such as MFM
(506), RLL, ESDI, IDE. I will put together what I already have, what is sent to
me, and what I make up in a file to either post or mail directly to you
depending on the size....thanks in advance.
