is really a funny scientific calculator! An identical calculator was sold as TI-1744,
the name convention of a BASIC calculator. But we know this confusion from other "scientific"
calculators of this era. Remember the TI-15.
Dismantling the TI-18 reveals indeed an identical single-chip calculator circuit manufactured by NEC.
The design of the TI-18 was slightly changed during the production run. Please notice the "AUTO SHUT OFF" description found on later TI-18.
