The
TI-503SV followed the TI-503+ and added a square-root
function. The TI-501 line of "cheap calculators"
started already in the year 1982 and brought us models like the TI-502
or the TI-507.
This
early TI-503SV from the first production year uses still a conventional
IC-housing. Later models of the TI-503SV used the chip-on-board (COB)
technology.
We know the Sharp LI-3154 calculator chip already from the cheap TI-1726.
