Hm, what I mean is the following.

1. In graphics mode (with uppercase letters and graphics characters),
   everything is the same as with later models.
   This is the power-up mode.
2. In lowercase mode (with uppercase and lowercase letters), the upper-
   and lowercase characters are swapped.
   poke 59468,14, if I recall right.
   This means, that if you type the word "Hallo", you must type
   unshifted H
     shifted allo
   In other words, the abbreviation for the LIST command looks like
   Li instead of like lI. (Doesn't Li look much better? I thought so.).

   iF YOU ARE RUNNING PROGRAMS MADE FOR pet MODELS 30XX OR LATER,
   TEXT ON THE SCREEN LOOKS LIKE THIS ;-)
   and the other way around too.

   (perhaps this is where BiFF started with computers?)

At our computer club we had one old PET with such a charrom but otherwise
it had 2.0 ROMs. I suspect there were more such machines.

I guess it's for APL. I think that was one of the languages from Waterloo
that ran on the SuperPET.
