Texas Instruments Model PC-100C Print-Security Cradle

This device, used with a TI Programmable 58 or 59 calculator, performed a variety of functions. The printer could show the contents of the display at any time, list programs in program memory and the contents of data registers, print results from a running program, print each step of calculator operations, list program labels and location, print alphanumeric messages, and plot data. The PC-100C also served as a security cradle, providing a secure place to leave the calculator and also allowing recharging of the calculator while the printer was in use.
The thermal printer, with its 2 ½ inch (6.4 cm.) wide tape, is on the left; the mounting bracket for the calculator is on the right. In front is a storage compartment for the battery pack from the calculator and for the cover of the mounting bracket. A lock (with key) is in the middle.
A sticker on the bottom of the object reads in part: TEXAS INSTRUMENTS (/) MODEL PC-100C (/) PRINT/SECURITY CRADLE. Text below this reads: SERIAL NO. 293181 ATA2378.
