It's a hardware thing. It is my understanding that any SCSI bus that goes through 1 of those 25-pin connectors that Apple used from the Mac Plus all the way up through the beige G3s, has to be "dumbed down" a bit, & can't do all the things that you can expect of a true SCSI-2 bus, including speed. The standard (per spec) connector for SCSI-2 is 50-pin (centronics or mini). The standard for SCSI-3 is 68-pin. -- Bill Art page: <http://geocities.com/[EMAIL PROTECTED]> -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
