The #ApolloGuidanceComputer: A marvel of engineering that powered the moon landing over 50 years ago. Its groundbreaking design and software laid the foundation for modern computing and space exploration https://www.youtube.com/watch?v=B1J2RMorJXM #tnmoc

@alleycat I donated 2x #atari portfolios (mint condition with accessories) to the National Museum of Computing at Bletchley Park. #tnmoc

I found them in my site engineering kit box from the early '90s, when I was clearing the garage a few years ago.

I enjoy seeing them on display when I visit 🙂

Had a great day at #TNMOC for the Econet LAN party. The A4000 and RISC PC seemed to go down well! #AcornRISC #RISCOS

Going live from the National Museum of Computing. We have created the biggest ever Econet network, and I'm going to try an early 80s MUD called Cave

This event at #tnmoc @ #bletchleypark looks interesting

The Bombe had up to 8 drum types available, colour-coded to show the different wiring of the real #Enigma rotors: I red; II maroon; III green; IV yellow; V brown; VI cobalt (blue); VII jet (black); VIII silver. We'll need to choose from all of them to put on #VirtualBombe. #tnmoc #bletchleypark

The final set of controls are now in place on #VirtualBombe. The switches on the right of the Bombe control which of the 3 chains (the rows of drums) are active, which step and which terminal has the current injected. #tnmoc #bletchleypark

This week, I've been finding out about the "letterbox" display which is situated on the right-hand side of the Turing-Welchman Bombe. For a stop, it shows a possible steckerbrett position (the plugboard cables on the front of Enigma). #VirtualBombe #tnmoc #bletchleypark

The basic wiring layout on the rear of #VirtualBombe is now complete and labelled. I've also been working on enabling the bridges which connect together the input & output of two "Letchworth Enigmas" (1 set of 3 drums which make up an Enigma). #tnmoc #bletchleypark

Would you Adam and Eve it, when we bunked down at the hotel last night, guess what was playing on the TV? The Imitation Game, telling us all about how #Turing helped break Enigma. Having just seen the reconstruction at The National Museum of Computing, it was very fitting. #TNMOC #Enigma

Had a good drive up to Milton Keynes to visit The National Museum of Computers at Beltchley Park. When we arrived at a rather innocuous set of ex military huts, we wondered what we'd arrived at. It wasn't your "traditional" museum, where you start at A and have everything explained to you. It was a "living" museum, where you learnt from people who helped rebuild these incredible machines. Mind totally blown, and an amazing day.

We'll leave messing with the drums on #VirtualBombe & play with the wiring! The "menu" was wired on the rear of the machine using double ended 26-wire connectors. If you've seen Virtual Enigma, you may recognise my wire physics in action! #tnmoc #bletchleypark #threejs

Lots of tech people on here, please consider making a donation to TNMOC (The National Museum of Computing) they are in dilapidated buildings currently and need roof replacements to continue with work. If this project doesn't get fully funded then we are in danger of losing a lot of our computing heritage.

The Bombe couldn't step the middle row of drums quick enough to keep sensing so for every 3 revolutions of the top drums, the 2nd set would only carry twice. I've been working on duplicating this on #VirtualBombe - details in the video. #tnmoc #bletchleypark #bombe

@flexion ZuluSCSI is amazing. I have it in my Sparc20 and running the Indy on display at #tnmoc

I've been working hard learning how the Turing-Welchman Bombe does it's thing & coding it into #VirtualBombe.
Finally got some results this morning so let's pop some rotors on and have a quick demo of how it's looking so far. Hope you like it! #tnmoc #bletchleypark #ww2 #cipher

@Crud3_Gamer I found a mint #AtariPortfolio in my garage a few years ago. Had a carry case, parallel and serial adapters, and some flash cards. I donated the lot to #TNMOC at #BletchleyPark

Merry Christmas all! Here's a first early render of a possible #VirtualBombe! Would you like to have your own Bombe and learn how to crack #Enigma messages? yep - me too! Keep following & I'll see what I can do to make that happen.

Of course, another alternative for the next project is to complete this. Always wanted to dig more into the Bombe machine and find out exactly how it really works and would be a fab addition sitting next to Virtual Enigma. #tnmoc #bletchleypark #bombe
