[Coco] Fwd: Disto 4-in-1 card manual

[Mark Marlette]

There are many issues with the 4n1's SCSI port. Electrically it 
doesn't even follow the SCSI spec. SCSIsys was never finished and was 
wounded in many aspects. I wouldn't waste my time on either.

Get the TC^3 with SuperDriver, jump 15 years forward in technology. 
Have it work right out of the box. But then again I'm partial to it.
