The PC-100C Printer Cradle followed the PC-100A soon. It can be used with the TI-58, TI-58C and TI-59. PC-100C_1.jpg (56760 Byte) Its thermal printer has 64 alphabetic, numeric and special characters which can be printed at the rate of 60 characters per second. Up to 20 characters can be printed per line on 2.5 inch wide thermal paper.

The PC-100C can also be used to print, list or trace program steps as an aid to debugging. 

PC-100C_2.jpg (24852 Byte)The PC-100C Printer Cradle offers some more features than just printing. It functions as a power-adapter and also has a storage/ charging compartment where you can charge the battery pack. The calculator (and battery pack compartment) is locked solidly to the Printer Cradle with the use of a key.

PC-100C_PCB.jpg (605149 Byte)Dismantling the PC-100A printing cradle reveals a rather complex printed circuit board (PCB) based on the TMC0250 Printer/Display Chip from the TMS0200 Chipset for 12-digit Desktop Calculators. The two additional TMC0561 and TMC0569 BROMs (Bare Read Only Memories) found in the PC-100, PC-100A and PC-100B to support the SR-52 respectively SR-56 calculators were removed in the final PC-100C.

American Micro Products introduced with the Module Selector a very interesting product fitting into the charging bay of the PC-100C Printer Cradle.

The PC-100C is featured in the Texas Instruments Incorporated bulletins CL-276A and CL-382 dated 1979 resp. 1978.
Find here an excerpt from the Texas Instruments Incorporated leaflet CL-199J dated 1981:

PC-100C Printer/Plotter

Provides the convenience and efficiency of hard copy printouts.

The PC-100C printer/plotter turns your TI Programmable 58C or 59 into a quiet, high-speed printing calculator that prints, lists, and traces your program. Just push the LIST key for a printout of the entire program. Push the TRACE key and every calculation that’s performed in your program is printed – the full number and the operation. Provides alpha and plotting capabilities. Prints 64 characters with a maximum line length of 20 characters. Print headings and data labels. Plots curves and histograms. You can even use the alpha capability to build prompting messages into your program.
Uses a non-impact, thermal printer.
