I'm not sure when the first reference to a pocket-sized computer was; this novel was published in 1974. At that time, the smallest computer was probably a mini-computer. One of these machines plus a drum memory for storage were about the size of a small washer and dryer.
Apparently, they also included some sort of wireless link, because (elsewhere in the novel) it says that, when the officers were off duty, they "could always be reached on their pocket computers."
Another early mention of a small "pocket computer" or note-taking device with some mathematical functionality built-in is the calculator pad from Foundation by Isaac Asimov.
Asimov also mentioned a "pocket-computer" in his 1975 story Point of View.
As far as I know, the first pocket computer sold as such was the TRS-80 PC-1. Comment/Join this discussion ( 15 ) | RSS/XML | Blog This | Additional
