Subj:	RE: RRD42 and 80386

Hi,

The RRD42 is actually a Sony CDU-541 with a slightly modified controller, so
that it shows up as an RRD42 rather than a Sony.

When used on a VAX, the "mode" jumper of the back of the physical drive is
linked. For use on a PC, this link should be cut. I've connected a very small
switch to this link and fitted it in the right hand side flange of my external
RRD42 so that I can move it between systems by flicking the switch - the jumper
controls the "Block size" of the drive.

I use an Adaptec 1542B SCSI adapter with Adaptec's SCSI CD drivers - You select
the SOny driver if you are using ASW-410 s/w. No problems. The system I'm using
is actually a 486/50, but this should make no difference. The drive also works
very nicel;y with Windows NT (aka VMS for the 1990s) on the same configuration.
