The key fact is "five years old." The fact is, most SCSI devices until the advent of the ASPI standard were not really designed to be SCSI in the chainable sense we think of now. They were designed to be run from a card specifically designed to run the device and with a driver that spoke directly to the board. No chaining was possible unless it was precisely the same device. The ASPI standard, which requires some chip support as "hooks" in the device, is used by a ton of devices now and CorelSCSI has led the way to a true SCSI interface–but it can't be responsible for the mistakes of third party makers in not joining the club. If a device is not ASPI compliant it can't be run by an ASPI manager any more than if it were an IDE device. Period. MASTER.TXT and PROLIS.TXT here in LIB3 list all the devices CorelSCSI certifies that it supports.
