A Very Old Computer...and Some Slightly Newer Ones...
Of course, the high-point was the Colossus, although the two hour lecture on cryptography and the display of old (1980s) home computers were excellent too. The machine really does live up to it's name, although, for being so old, it's surprisingly powerful - it's touted as being as powerful as a Pentium 2, but I'm not sure how they tested that...
The whole visit was extremely informative, especially the part were I fooled around with the ZX80's BASIC compiler!

I would like to say a special thanks to Tony Sale for his excellent tour and generosity.
