WRONG!

There are two TI-85 boards (minor, but fairly compatible diferences). The
TI-82 has two chip layouts that use the same board, but jumpers (resisters
with a "0" on them representing zero resistance) are used to select which chip
is used. The TI-83 also has at least two versions. The TI-92 has varying
memory chip configurations. The TI-81 and 86 I'm not certain about.

ROM 10 is different than other TI-85 ROMS. I'm not sure about the others.
