[Coco] SCSI drive and enclosure

Speaking of SCSI drives, I have a 20 or 30 GB drive and an enclosure w/power supply. Used a couple times on my PC for backing up data, but no longer need it. Should still be good. Will ship all with the cable in the US for $40. The enclosure is a half height external drive with the big SCSI connector, pass through connector, and a think the termination resistor is there too (clips on the pass through connector). If anyone's interested drop me an e-mail! I'll have to figure the shipping for Canada.
