|Colossus at TNMOC|
However, the TNMOC has graciously agreed to let me offer this invitation to a lucky reader of my blog. The special viewing will be on an early evening in the first week of September. There will also be an opportunity to see around the rest of TNMOC then and earlier that afternoon.
To win all you need to do is be the first person to tell me who the designer of the Colossus computer was. Please leave your answer in the comments of this post along with your contact details, these will not appear on this blog.
You can still sponsor a valve on Colossus, and I highly recommend a visit to TNMOC, and of course Bletchley Park is absolutely fascinating.
