I recall all the notice back in the day that the BASIC 1 ROMs worked
with the first dot matrix printer released for the PET (CBM 2022) and
not the 2040 floppy drive, but does anyone know the specific issue?

I'm slightly curious about what it might take to "bake in" replacement
IEEE routines for a program for which one had source to call "fixed"
routines not the buggy ones in ROM.  These routines would look largely
like what's already in the BASIC 2 ROMs, I'd figure, but for now, I
really just want to know what the bug(s) was/were.

If that's covered in Raeto West's book or somewhere equally
accessible, I'm happy to just get pointed at the literature.
