I can't remember exactly, but the 100A was definitely 4.xx series (maybe 
4.12?) while the 100B was definitely 5.xx series (maybe 5.03A).  I've 
never seen different values on any Rainbow, though, suggesting that the 
boot roms were finalized before manufacturing started and never again 
updated.  Could be wrong, though.

Some Rainbow's have different character set ROMs, like the Technical 
Character Set ROM, but that doesn't change the firmware version on the 
boot menu.
