YES, IT IS!

Or use even the 310654-05, it is even newer.

the -03 ROM has some bugs. IIRC, it has problems recognising
single-sided disks (i.e., 1541 disks), which may result in problems
every now and then.

The -05 ROM has it fixed. The -04 ROM is much "nearer" to the -05 than
it is to the -03, thus, I believe most problems should be fixed, but the
-05 is more reliable, anyway!


I doubt it would have helped you with your problem at hand, though.
Anyway, you should avoid the -03 ROM.

Regards,
Spiro.
