A huge post that was really very good :-)



A couple of things though ... the CSPPC card does not have a terminator on it so to plug 3 devices into it you'd need a 5 connector SCSI cable and do :

ActiveTerminator - CSPPC - Dev1 - Dev2 - Dev3(Terminated)

Also the statement about mixing Ultra, Narrow and Wide isn't a problem, the bus will only step down to slowest device when talking to that device ... so if you are talking to an UW SCSI drive you'll go at 40Mb/s if you start talking to a CDROM with a Narrow SCSI device you'll drop to 10Mb/s (or 20Mb if it's ultra)

So in the example above you could put a 68to50way converter on the back of a CDROM drive and put it in the chain ... HOWEVER .. DO NOT put that device on the end of the chain and terminate it, put it in the middle and use a 68way active terminator on the end.

In the basic A4000D its a bit of squeeze when using the CSPPC SCSI but worth it, if you;ve got a tower case it's easy to cram it all in.
