[DaZZa <dazza@nospam.zip.com.au>]

Someone aske the other day about the different SCSI standards and
connectors - there's a pretty good list in this month's APC - but here
they are.

Narrow SCSI (SCSI-1)	5 Mb/s	Single ended 50 pin	8 bit	10 Mhz bus
Fast SCSI (SCSI-2)     10 Mb/s	Single ended 50 pin	8 bit	10 Mhz bus
Ultra Scsi	       20 Mb/s	Single ended 50 pin	8 bit	20 Mhz bus
Fast Wide SCSI	       20 Mb/s	Single ended 68 pin    16 bit	10 Mhz bus
Ultra Wide SCSI	       40 Mb/s	Single ended 68 pin    16 bit	20 Mhz bus
Ultra2 SCSI	       80 Mb/s	LVD(*) 68 pin	       16 bit	40 Mhz bus
Ultra160 SCSI	      160 Mb/s	LVD(*) 68 pin	       16 bit	40 Mhz bus

Notes: "bus" indicates the bus clock speed for each type
       "LVD" is low voltage differential - special cables and signal types
