Lines: 10 On the Acorn SCSI card that I have, there is a facility to do background transfer, by setting b29 of r1 and a address to call in r6 on entry to SCSI_op. Is this facility unique to the acorn card? is it used in riscix? Which cards are actually compatible with the riscix device drivers? Since acorn have released riscix to ordinary archimedes owners it might be of some benefit to know this.. Andy
