Acorn 1Mhz bus to simple SASI adapter

Adaptec SASI to MFM converter (has a cpu, rom, ram of its own)

>This connects to drive : NEC D5146H

40 Mb, 615 cyls, 8 hds, 17 spt, precomp 128

Interestingly, this drive is RLL capable, so it becomes a 62Mb unit with
a suitable controller. (no, the Adaptec card won't do it)
