Well I'll tell you now this bird is a very strange one indeed.

I beleive since your at least getting the device manucturer
(DEC from below) that. You'll either have the external item
or a cd-rom device attached to an scsi<->phillips(cdrom)
adapter ? ( Yes Phillips and a very early model too, 1x speed )

On DEC equipment this is polled in a slightly odd way, but
supposedly within scsi spec. ( un-huh, right ;-)

gosh darn somewhere around here I have a manual,
( not much of one ) I'll see if I can dig it up.

I know this don't help much. JimL
