The original RamFAST, produced by CV-Technologies, used a Hitachi processor. When Sequential Systems bought the design and did their own manufacturing, they replaced it with a Zilog processor. The "3.01EZ" ROM firmware put the Zilog CPU (Z180) into Hitachi CPU mode (HD64180). The 3.01EZ ROM works happily with the CV-Technology card with the Hitachi processor present.

The 3.01E and 3.01EZ ROMs both contain a bug involving the built-in tape backup software's RESTORE function.
You could create a backup with no problem, but it would not be able to restore/write it back. Revision "F" resolved that bug. The 3.01E/EZ ROM is otherwise completely safe to use with hard drives. It does not cause data corruption.

The 3.01F ROM supersedes the 3.01EZ, it still contains code to make it work with the Zilog processor.
