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.
The
street price of these calculators was around $3, earning money was difficult but
a cheap construction and low labor 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.
The TI-503 was replaced in 1995 with the more stylish TI-503+.
