Well, if it's small and has got two positions, it's most likely the
switch for the terminator.  Other possible functions: on/off switch for
the CD-ROM drive, or maybe the selector switch for the SCSI ID.

That is very odd.  Well, assuming it's not running off vacuum energy,
doesn't have a nuclear battery, or a perpetual motion machine inside it,
I suppose it really must be meant to get power from the SCSI bus.  I
feel that this isn't right myself.

I expect if you asked on the Classic Macs mailing list, someone would
have some firm information.

Well, that'll be why it's not working.

Not legally, no (at least, not that I've heard of).  But if you drop me
an email (rebecca@astrid.u-net.com), I can email you a genuine System
7.1 version of the Apple CD-ROM extension as well as the version that
came with 7.6 (if I can find it) which is the only one that'll work with
non Apple CD-ROM drives.
