Digital electronics engineer James Newman, has built a ten meter long, two meter tall processor using transistors. Running at speeds up to 8 kHz the project ran out of control with total spend of forty thousand UK pounds (£40k). Unlike a computer on a chip, the system allows visualisation of the processes and architecture of a modern computer central processing unit (CPU). James is looking to site the computer in a museum or have it tour the UK to educate the public. Currently it’s possible to visit the computer during open days in James’ lounge were the machine was built.
A physically large chunk of memory built using LEDs allows visualisation of the data stored, and can be used to play Tetris!
