The TRS-80 PC-1.

Radio Shack Pocket Computer ( The TRS-80 PC-1).

Maybe the design is not attractive, but at that time.... this is the most famous "pocket pc".
The TRS-80 PC-1 is the first-ever BASIC-programmable pocket-sized computer! It's actually the Sharp PC-1211, sold by Radio Shack in the US.
This new TRS-80 Computer is another "first" from the company which brought you the best-selling, world renowned TRS-80. A truly pocket-sized Computer (not a programmable calculator). Of course it is an ultra-powerful calculator too... And it "speaks" BASIC - - the most common computer language, and the easiest to learn. You'll soon be impressed by the phenomenal computing power of this hand-held TRS-80 - - ideal for mathematics, engineering and business application.
