Computer history: CDC systems


Control Data Corporation Systems at TNO Waalsdorp

The TNO Physics Laboratory, the forerunner of the TNO Physics and Electronic Laboratory and the current TNO location The Hague Waalsdorp, used various Control Data Corporation (CDC) mainframe systems and systems manufactured by several other computer suppliers in the seventies through the nineties. This computer history page contains technical aspects based on the memories of the computer pioneering time by operators and system programmers. We also used old photographs and sparse documentation that survived clean-ups.
