Texas Instruments PC-100A Thermal Printer / Security Cradle
- Type: Calculator Accessory

One desk console includes a thermal printer, battery pack recharger and a security lock to keep your calculator being walked off with (although nothing really kept the whole unit, calculator and all being carried away.) Used with the TI-58, TI-59 and the older SR-52 and SR-56.
I don't have a key, but clever use of a screwdriver and a pair of diagonal cutters did the trick...
