Prom Replacement

When replacing PROMs A, B and C with different version, replace them in a set.

Version 3.2 can replace 3.1, 1.0 and 0.7 Version 3.1 can replace 1.0 and 0.7 The reverse does not hold true.

ROM 3.4 can replace 3.3D and vice versa. NOTES:

PROM D is required only when OC-8 or DCB BOARD is present. PROM D must be used together with A, B, C of 3.2 version and up. PROM D contains diagnostic programs. Refer to P.46 for test procedure.

Difference between 3.3D and 3.4D is that the latter has debugged diagnostic program.
