These dumps are broken, there are several bytes missing from them. The
question is: did they get lost when I dumped them to tape on the PET or
when I read them back on the VIC? Does anyone know if the clock speed
differences can cause problems here?

Basically, I saved them doing

10 OPEN1,1,1,"ROM DUMP"
20 FORI=45056TO65535:PRINT#1,CHR$(PEEK(I));:NEXT

on the PET and copied them to disk on the VIC back using

10 E$=CHR$(0)
20 OPEN1,1:OPEN2,8,2,"0:ROM DUMP,S,W"
30 FORI=45056TO65535:GET#1,A$:IFA$=""THENA$=E$

(a simplified view of what I did)

Should I try reading the tape on my C64 or my C128, perhaps?
