If you feel familiar with this rare scientific calculator sporting the [1/x], [x2], [sqr(x)] and [PI] keys, view the SR-11 introduced already in 1973 and combine it with the TI-30 STAT.
this TI-18 SLR manufactured in June 1985 by a non-disclosed OEM (Original Equipment
Manufacturer) in Taiwan reveals a clean design centered around around an unknown
Toshiba single-chip calculator
circuit soldered on a double-sided printed circuit board (PCB) and powered by
four solar cells.
Inspecting the PCB of this TI-18 SLR calculator brought our attention to a small mark reading S33T-10, we discovered already similar marks reading S32B-II and S39A with the TI-108 resp. TI-1895 II. The Date code C-0685 located on the back of the featured calculator and the PCB-Mark S33T suggests a design of Kinpo Electronics, Inc., manufactured in their Compal Electronics, Inc. plant. We started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
