A few years ago now I visited the Nexon Computer Museum on Korea’s southern island of Jeju. It contains thousands of personal computer, video game consoles, arcade machines, and associated software items. One thing that sets them apart from other collections I have visited is their collection of retail packaging.
They have an operational Apple I, and a variety of machines principally from the USA and Korea.
There is a 360 degree virtual museum tour (requires Flash, switch to ENG before starting to avoid having to share Facebook credentials).
My Google Photos album of the museum gives away my personal interest in Atari.
