IPSJ added 23 computers to “Computer Heritage”


We are living in the age of IBM PC-compatible computers hegemony. But once there were so many calculating devices all over the world, each of them so unique and distinguished.

IPSJ, Information Processing Society of Japan has added 23 computing machines to their "Information Technology Heritage", including Tiger hand-cranked mechanical calculator.

Read on for the complete list of regsitered computers.
