Had a brilliant time at the #rc2014assembly today.

Probably spent too much money, but there you go.

Some great talks and some lovely people.

Also really good to have some time looking around #TNMOC too.

Hoping to be there are the #rc2014assembly today, but won't be there right at the start.

Fingers crossed, I'll be there just before lunch!

It's been a while since I was last at the #TNMOC

Went to retro electro jumble. May have bought a thing. I shall call him 'Rusty' for that was the description of him on the condition sheet pinned to the board. At least he still has his motherboard...

I've never had a PET so this seemed like a good place to start. 😁

Today's Supporters’ Day was a fantastic celebration of our #Community and the work happening behind the scenes at #TNMOC!

🖥️ #Volunteer Malcolm C shared insights into the Argus 500 #Restoration, bringing this ex-nuclear power station machine back to life.

As we approach our 20th anniversary, we're reflecting on what makes #TNMOC special.

One visitor said: "TNMOC is a marvelous repository of computing history."

For two decades, we've preserved the stories of those who shaped our digital world. What does TNMOC mean to you? 👇

How the EDSAC computer changed science in the 1940s and 50s Volunteers at the National Museum of Computing in Bletchley Park, UK, have been constructing a working replica of an EDSAC machine, one of the world's earliest general-purpose computers.

We were thrilled to welcome New Scientist to #TNMOC to film EDSAC. As project lead Andrew Herbert put it, "We're kind of doing archaeology" - piecing together how this pioneering machine operated in pursuit of a working rebuild.

I've just recently set a new VIC20 in our PC Gallery with this on at #TNMOC. My first time using a VIC20, a C64 was my first computer. Cool game for the machine and handy for us as it's on cartridge so easy to load to each day. So far seems popular with the visiting schools!

#TNMOC is turning 20 🎂

On March 30th, we celebrate two decades of preserving and sharing #ComputingHistory

Over the next few weeks, we'll be reminiscing about the last 20 years. To start, we'll leave you with this aerial view of the #BletchleyPark site, with Block H at the top
