I've got an Imation external 8/20 SCSI CD-r, flashed to Plextor with firmware ver. 1.07. The setup includes the 50-pin SCSI external cable, power block, and the SCSI card, an Adaptec AHA-2930.
For prices.....how about $75 for the burner and cable only, $20 for the card.
It has burned possibly 40-50 cdr's (I didn't use it much), works absolutely flawlessly. Has copied anything I've asked it to and has NEVER produced a coaster.
I've also got a 256MB stick of Kingston PC133 ValueRam. Shows as CAS2. $25.
Thanks for your time.......
