_I_ care! I reverse-engineered and mostly commented the C-64
interpreter. Haven't posted it yet. Mine is live source that
compiles byte-exact (including cruft!)
I even added conditionals to support versions for the VIC-20
(with lots of RAM - tested under VICE) and the PET (32K Basic 2.0
PET, also tested under VICE until I can repair my old 2001).
I'm holding back the source until I fix the BASIC 4.0 bug (I
think I am reusing a zero-page location that is being whacked
by $FFD2 or the "editor" routines in the $E000 ROM. If I knew
which one it was, I'd modify my zero-page usage. I haven't
had time in the past few years to put the finishing touches on
this, but it's on my ever-growing list...
