  "Toshiba XM-3401TA" - Just a plain old
CD-ROM drive, I think it's a 2x.
 I could boot the mini-VMS in SYS1 from it, and when I booted VMS from my
 hard drive, I could mount CD-ROM discs fine. No problems with operation
 at all. 
I'm fairly certain that this is the same as a RRD-42.  My RRD-42 is the
same as the Toshiba drive that was in my SparcStation 5, and yes it is 2x.
That's probably why it worked just fine.
