This 1951, 2.5 tonne beast has just been rebooted after restoration.

It's difficult to compare to present day machines as they are so far removed. However, it is decimal rather than binary and originally had 20 x 8-digit dekatron counters which is roughly 160 bytes of RAM (later upgraded to 40 x 8-digit dekatron). Input via ticker tape and took up to 10 seconds to multiply two decimal numbers.
