Can anyone tell me the difference betweed SCSI 1 and SCSI 2 and which I should
select with the NEC 74-1? <paul>
Hi Paul,
SCSI 2 is a "superset" of SCSI 1… that is, it's a revised version of the SCSI
standard that corrects some problems that happened when people tried to push
SCSI-1 to it's limits.
Basically it has a higher transfer rate, possible through different "transfer
modes" that weren't in the SCSI-1 standard, but there's a number of nifty
features that were implemented with SCSI-2. However, the CDR-74 that's sitting
on my desk isn't a SCSI-2 device, so it wouldn't be able to take advantage of
any of those features… SCSI-1 will still plod along at it's own pace with a
SCSI-2 controller, because the device needs to be designed with SCSI-2
compliance. However, I don't have any information about the CDR 74-1… maybe
it's SCSI-2?
You might try redirecting this message to all, because there's big gaps in my
knowledge of SCSI-2…
