Excerpts from Ready Player One by Ernest Cline:
The museum’s bottom level, located in the planet core, was a spherical room containing a shrine to the very first videogame, Tennis for Two, invented by William Higinbotham in 1958. The game ran on an ancient analog computer and was played on a tiny oscilloscope screen about five inches in diameter. Next to it was a replica of an ancient PDP-1 computer running a copy of Spacewar!, the second videogame ever made, created by a bunch of students at MIT in 1962.
On each table there was a different classic home computer or videogame system, accompanied by tiered racks that appeared to hold a complete collection of its peripherals, controllers, software, and games. All of it was arranged perfectly, like a museum exhibit. Looking around the circle, from one system to the next, I saw that computers seemed to be arranged roughly by year of origin. A PDP-1. An Altair 2600. A Commodore PET. An Intellivision. Several different TRS-80 models. An Atari 400 and 800. A ColecoVision. A T1-99/4. A Sinclair ZX80. A Commodore 64. Various Nintendo and Sega game systems. The entire lineage of Macs and PCs, PlayStations and Xboxes.
