RE: A83: Inside the TI-83




>From what I know, the TOSHIBA chip is actually the z80-clone chip (there's
no actual zilog chip) and the TI chip is the ROM.  The other chip is
probably the RAM.  That's the way it is inside the TI-82.

it would probably help if someone can identify any part numbers on the
chips.

The Z80 is supposed to have 40 pins, but I'm not sure about this TOSHIBA
clone (though I would assume it should be the same)
