The National Computer Museum at Bletchley Park

I posted a little while back about the good news Bletchley Park received and said that I’d like to visit and take a look around the National Computer Museum

Well as a bit of a weird coincidence I’d completely forgotten that we’d arranged a visit to Milton Keynes on the Saturday immediately after the post

Said friends actually live in the Bletchley area which made things even easier so I dragged one of my friends along

First up we had a quick look around the mansion which was a fantastic looking buildingMansion 

In here there were details of the history of some of the famous names such Alan Turing (wikiepedia entry here)

After that we had a quick look through the huts where all the code breaking took place

After that we jumped onto the end of one of the tours and heard all about “bombes” that were used to break the Enigma Machine

DSC_0261 I won’t try to explain how the bombes worked!

Then it was onto the part I’d been waiting for and the National computer museum where we got to see the Colossus rebuild project 

DSC_0265 Colossus was the world’s first programmable computer.

DSC_0278 It had no storage though and all output was directly to a typewriter

DSC_0276 Calculations were performed using valves and the black valve on the left of this picture is an original valve used during the war! Apparently they have about 10 years worth of spare valves so if you have any old gadgets lying around that have valves they welcome donations

The rebuild project has been led for the last 14 years (!) by the legend that is Tony Sale. Most of the documentation was restored and whole project started from just 8 1945 photographs and some fragments of circuit diagrams some of the original engineers had been keeping illegally (good job geeks are hoarders!)

It was onto the museum proper after that and I was in my element!

DSC_0294 Calculators and PDA’s! I had one of the Psion’s in this picture!

DSC_0296 BBC Micro! I actually owned one of these CUB monitors as well. My dad hacked it up so when it was plugged into our spectrum we had sound and volume control. What a mod!

DSC_0303  Radar!

DSC_0306 Punch cards!

DSC_0312 DSC_0309

DSC_0317 The very first PC we owned had one of these in. Along with 8MB of RAM, a 50MB hard disk and a quad speed CD-ROM

DSC_0320 Legend!

DSC_0328  An Apple Mac!

DSC_0326 Had both of these. An Atari ST and a Amiga 500

The first two computers I have any memory of! Look at the rubber keys!

DSC_0362 Why is the screen the wrong way round? Because it’s trying to look like a sheet of paper. This system was just a word processor. Look at the size of it!

DSC_0367  I want a desk like this in my office!

I’ll stop there….as you have probably guessed I took a ton of photo’s which I then spent the next week boring friends and family with

I had a great time with my only “criticism” (not really the right word) was I was expecting to see more hardware as there appears to be lots of gaps in the time periods (Other than a PET I didn’t see much commodore kit for example). But I do understand it’s still pretty new and things are being added all the time and they are running on a shoestring (donate!!) as the museum itself is free! It’s Bletchely Park you have to pay to get in

If you have any interest in computer history do something to support our computing heritage!
