The TI-503 is one of the cheap calculators introduced with other TI-50x products like the TI-502, TI-507 or the TI-503SV.
street price of these calculators was around $3, earning money was difficult but
a cheap construction and low labour cost of mainland China made it possible.
Dismantling this early TI-503 manufactured in February 1991 by Nam Tai Electronics, Inc. in China reveals a single-chip calculator circuit using a package in chip-on-board (COB) technology.
It was replaced in 1995 with the stylish TI-503+.
