TI-501 was introduced two years after the TI-1015 and
similar calculator chip in a somewhat smaller housing. We can't locate any
exciting feature at this calculator.
The TI-50x line introduced some other "economical" calculators like the TI-502, TI-506, TI-507 or the TI-503SV. Another TI-501 appeared 17 years later, view it here.
Dismantling this TI-501 manufactured in 1982 by an unknown
OEM in Taiwan reveals a clean design centered around a Toshiba
single-chip calculator soldered on a single-sided printed circuit board
(PCB) and powered by two AA-sized batteries.
Inspecting the PCB of this TI-501 calculator brought our attention to a small marks reading 807C-2 and we started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
