I had (it's now defunct) a 386 from Unisys with a Micropolis (they're defunct now, too) SCSI-1 HDD.
Recently I thought of making use of that drive again. I sought for information about it on the Net (it definitively supports only the SCSI-1 interface, not even a narrow SCSI-II). And about the SCSI interface itself, truly complex as it may be.
But what I haven't been able to do is determining which type of PCI SCSI bus card would fit my needs best; not uselessly excesive, nor too limited for using it with possible more modern SCSI drives.
Should I buy the self-labeled "for SCSI cd" type of card? Are they any different from cards that also are SCSI-1 and made by the same manufacturer (Adaptec,Symbios...)? Is there any point in favouring the strangely cheap ultra (2)wide SCSI (40-80 Mb/s) range of cards, thinking about adding possible less obsolete drives ? What about lacking a bios?
I've been looking around and made a selection, among the most basic line:
- Adaptec AVA-2904CD
- Symbios SYM20810
- and, by Advansys... a card, ... well... their site is unreachable just as I am writing this post (they CAN'T be defunct, TOO, can they? Pheow... a truly macabre post, this)
Any suggestions? (they certainly will be merrier and shorter than this slow-death--prone piece of epistolar junk)
let me just add my ¢2. There might be a problem because many of that SCSI-1 standard commands were optional, and no guarantee that a particular peripheral even marked as SCSI-1 would support the harddrive.
