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)
