There was also 40.70 for the A3000 and A4000(D).
They were the same as their 40.68 parts, except for an updated SCSI/IDE driver. But this caused problems on some machines so they went back to shipping 40.68.
IIRC there was also a 40.68 for the A500-600-2000, but similar problems saw them go back to 40.63
MacroSystems Gmbh had a license for the 40.68 A3000 ROMs which they hacked like mad to work with the DraCo.
Edit:
Also, there were 2 different 1.2 ROMs. v33.180 and v33.166
