Thanks, you emailed it to me and Spiro. It's identical with the
archived copy of 1541-e000.901229-03.bin.
So, we learned that there is a fundamental flaw with the -03 ROM. This
is not surprising, because I've read previously that the 1581 doesn't
always behave correctly with the VIC-20. I haven't experienced any
problems myself, but I haven't used my 1581 much.
Spiro, maybe you should repost your BASIC program after fixing the
bugs that Andrew reported and fixed. Also, the program wrote 16
kilobytes to the file: 8 kilobytes of payload and 8 kilobytes of
garbage.
Theoretically, the $c000 ROM could be at fault. You could dump it
as well and send it to me, to rule out that possibility. But I really
doubt it, because mask ROMs shouldn't die that easily, and the drive
works with the -05 ROM.
