- This is, for the most part, no longer true. A long time ago, when
- devices "conformed" to a very ill-defined non-standard (later somewhat
- standardized as SCSI-1), people did have interoperability problems --
- because the SCSI standard wasn't enough of one to allow someone to
- build a working drive or host adapter without making their own
- interpretations. There was even this thing called SASI, the
- predecessor to SCSI, that was somewhat similar to SCSI and if you were
- really lucky, a SASI device might work with a host adapter that
- claimed to be SCSI.
-
- With the advent of the SCSI-2 standard, things have gotten a great
- deal better. Now, the biggest problem you're likely to have is that
- your host adapter won't be supported by the operating system you plan
- to run; however, this can be avoided by checking which host adapters
- the OS you're running supports, and getting one of them. If a SCSI
- device that was made relatively recently (i.e., 1990 or later) fails
- to interoperate with one of the mainstream SCSI host adapters (i.e.,
- Adaptec, Future Domain, DTC, Always -- NOT Seagate), I'd send it back
- to the manufacturer with a nasty note. This is 1993, not 1983, and
- anything that claims to be SCSI had better actually be SCSI, not some
- manufacturer's in-house abortion of same.
