Adjusted Inflation Price:
The lowest-priced pocket computer ever (at the time). The PC-4 lets you maintain up to ten short programs in memory or combine the programming area to allow longer programs. Each program can be identified with a single-key label and run simply by pressing the specified key. PC-4's BASIC language includes 23 commands, 15 functions and 10-digit numeric accuracy. Up to 16 commonly-used commands like GOSUB, LIST and STEP can be entered by pressing just two keys. Programs can accept words and names as data (strings of up to 30 characters). Edit and Debug modes make the PC-4 much easier to program than a programmable calculator. The keyboard-with a typewriter-style layout-includes 53 keys for alphabetic input, plus a 10-key numeric datapad. The big l2-character LCD has easy-to-read characters, plus 15 smaller mode indicators. It can handle numbers with exponents of 10 to the 99th power to 10 to the -99th power. Functions include trig and inverse trig, radians or gradians, log, exponent, square root, angular conversions and absolute values. Auto power-off saves battery life. Requires two lithium batteries.
