That's interestng. The footprint should be identical on multiple runs.

Do you also get other values for the footprint? Do you get any of these
values multiple times?

So we have a communication problem. The changing footprints indicate the
same.

How big is the rom2031.dump file after each run? Please run it multiple
times, and look at the sizes. Do they vary?

The 2031 should be the "best" drive for IEEE experiments with the ZF,
because the 2031 is very similar to the 1540/1541. All other drives
differ much more. Thus, I would be surprised if these a generic problems
that happen to all people.

I would check your IEEE cable. How long is it? Is it a (unshielded)
ribbon cable, or a shielded cable?

Regards,
Spiro.
