Before starting
Verify that the system software upgrade kit contains the correct number of EPROMs.
The 2902 MainStreet unit, Release 1, uses two EPROMS.
The EPROMs are labeled 80-2742-XX-YY, where XX identifies the variant number
of the EPROM and YY identifies the revision number of the EPROM. The number
2902 should appear on each label.
