RamFast SCSI rev B?

["Dan Yertzell" <Dan-Yertzell@worldnet.att.net>]

What are the differences between the different rev's of the RamFast SCSI
card?  I just picked up rev B board, and I know it's not the latest
version, so I'm wondering what to watch out for.  

I also received an Apple SCSI card, apparently not the "High Speed" SCSI
card.  Is this the card that only works with the Apple SC20 drive?  Or am I
remembering wrong?  The docs mention this drive and nothing else.

Also, if anyone has a SCSI drive, case & PS and cable you would like to
sell, I'm interested.  Alltech does not seem interested in taking my order
for a new one.   These people are way incompetent.
