Subject: Re: 50 & 68 pin SCSI-2
Yep, I have a 68 pin to 50 pin adapter on a drive on
my Amiga. 68 pin
is SCSI-3 and is 16 bits per transfer cycle rather than 8. There are 50
to 68 pin adapters, but the termination for half the buss is a rare
animal. I'd just have everything unterminated, and have a good active
term on the end of the 68 pin cable. The down side is everything is
slowed to SCSI-2 standards. I want to find a SCSI-3 CDrom to avoid that
if possible, as I just bought a SCSI-3 hd for my Linux box here. I want
to integrate a small SCSI-2 drive as my /swap partition.
I picked up a 50-pin-cable-to-68-pin-device from the local Microcenter a
while back. It's marked `ACTIVE' for some reason. Does the high byte on a
device need to be terminated too?
I believe Microcenter is a mailorder outfit, they might have a
comprehensive catalog somewhere. If there's a store local to you, it might
be a fun place to visit. Mostly expen$ive, but the place here was pretty
poorly managed, and some good deals could be found where the computer spit
out an obviously wrong price. (It goes both ways though-- I pointed out a
drive pigtail IIRC that was marked $49.95. The salescritter said it had to
be the right price. YMMV)
