WOM...CSIRAC was built 54 years ago [1949] and was the 5th electronic storage computer ever developed...originally called the 'CSIR Mk1'.
It was turned off in 1964, but unlike any of the others, it was not broken up for scrap but is still complete and 'could' be turned on again..
OK, so an 8086 XT with a serious head-cold could run rings around it, but its historical significance to all computer nerds makes it a 'must' to see if you ever get the chance...
