No, in fact, it is a Toshiba XM-3601B.  I was not aware of the difference. 
 Do you think a more modern prom would help or do I need to go out and find 
a Sun CDROM?  Additionally, I can read the disk under Windows NT.  That 
suggests that the drive will read the disk but without the right boot proms 
it doesn't matter?

This is the best lead I have gotten so far.  I really appreciate it and any 
further help you can offer

Thanks

Chris

Are you sure this is a Sun CDROM?  Sun CDROM drives use 512 byte sectors
(for stupid historical reasons you really don't want to know about).  All
other CDROM drives use 2048 byte sectors.  Although you might be able to
use standard 2048 sector CDROMs once the OS has booted, you can't get the
PROMs to boot from a 2048 sector drive.
