Centre for Computing History museum.

We spent the last week in Cambridge and I had to of course visit while my better half went shopping. Relatively small but I still managed to spend over three hours there, looking at the various computers (many of which I'd never heard of) and playing some games. So Bomber Jack on the Specky 48k, Drop Zone on the C64, Xenon on the Atari ST (I forgot how much I loved this game), Pong on Binatone and Centipede on an arcade machine plus some others.
The Megaprocessor is so cool, basically take what a CPU is and then build it from more discrete parts. So some picture of various things and a link to the museum.
