new driver sec(4) for the Acorn SCSI Expansion Card

Ben Harris committed a new driver sec(4) for the Acorn SCSI Expansion. Unlike asc(4), this driver uses the board's DMA system, uses the machine-independent WD33C93 driver, works on NetBSD/acorn26, and doesn't share a name with six other machine-dependent SCSI drivers. Not tested on acorn32, but it seems to work tolerably well on an A540. [0 comments]
