Editing Tandy Pocket Computer (section)

==Purpose==
Pocket computers were an advancement over early [[programmable calculator]] designs. In addition to providing users with scientific math functions in a small portable package, the devices also understood a form of the [[BASIC programming language]]. They included a [[QWERTY]] [[computer keyboard|keyboard]], of either [[chiclet keyboard|rubber capacitive]] or [[membrane keyboard|membrane type]], to use for entering the names of scientific functions and programming commands, in addition to a traditional [[numeric keypad]]. (The exception was the PC-7, which had a rectangular and alphabetically ordered keyboard, like most scientific calculators.) On some models, the [[alphanumeric]] keypad had a different type, form factor, and location than the numeric keypad.
