- I guess it really depends on where you get it from. If it is from an IBM
- clone dealer, maybe. They might bundle a controller with a drive, but it
- probably will be a cheap 8-bit card. It will also increase the price for the
- drive overall. If you buy from a Mac house, you will definitely not get one
- since Macs have SCSI built in. Assuming you have a 16-bit bus slot (or better,
- if you have EISA), I highly recommend getting a 16-bit (or better) card such
- as those from Future Domain, Adaptec, etc. to get the best overall performance.
- Forget getting an interface bundled with it. It rarely is worth the cost.
- As for the number of devices, standard SCSI supports 7 devices per host
- adapter (addresses 0-6). Most SCSI devices have dip switches or jumpers on
- them to set the address.
-
- By the way, if you are looking at hard drives, I highly recommend the Quantum
- SCSI products. Very reliable and fast!
-
- Good luck!
