Thanks, good idea.  I'll hook up a CD-ROM that reads CD-RW.

Can you take pictures? ;) 

Perhaps they are using SCAM to assign the ID and perhaps also for the

So far I've read that the 60pin connector was originally in drafts of
the SCSI spec, but was dropped eventually.

I can't find the plug anywhere yet.  I looked for a micro centronics 60
pin connector.  But I'm not sure, if that's correct.

Exactly.
