Want to be part of something amazing?

Adopt one of our unique tech artefacts or projects for a year and help us in our mission to create a vibrant, working museum that tells the story of computing’s history.

Our museum houses world-class pieces of pioneering technology that have helped shape - and save - lives and you could have your name next to them. You can adopt at Silver, Gold or Platinum level, or select a special kids’ option. Our packages are also available as gifts. Your backing will help support our vital work behind the scenes, in particular the volunteer-led work on repair, restoration and maintenance of systems.

All levels come with a certificate and an exclusive TNMOC gift. See full details below:

Sinclair ZX Spectrum

Sponsor level: Kids

With its rubber keyboard, compact size and rainbow-banded case, the Sinclair ZX Spectrum was a revelation in home computing. It might have just started at 16Kb of memory, but the Spectrum’s entry price of £125 put it within reach of young computer fans back in 1982. It brought to the home colour-screen computing and games previously only available in arcades.

Gift: Museum fridge magnet containing a photo of our Sinclair ZX Spectrum

ERNIE 1

Sponsor level: Kids

The nation’s monthly Premium Bond draw is a multi-million pound national pastime with winners’ numbers selected randomly by computer. The Electronic Random Number Indicator Equipment 1 (ERNIE), designed and built to pick those numbers for the first prize draw in 1956, used a system of electronic noise to generate random digits. Our museum houses a rebuild of the system, based on original documents, which shows how the numbers were calculated.

Gift: Museum fridge magnet containing a photo of ERNIE 1.


Colossus valve

Sponsor level: Kids

Colossus was central to the Allies’ work in cracking the military communications of Adolf Hitler and his top commanders in World War II from an encryption machine that  was capable of a near infinite number of variations. A key component of the Colossus success was the thermionic valves that could perform millions of switches per second. Each of Bletchley Park’s Colossi used a bank of 2,500 valves, helping make Colossus the fastest computer of its time.

Gift: Museum fridge magnet containing a photo of Colossus.


BBC Micro

Sponsor level: Silver

Before computers were commonplace in schools, in the early 1980s, the BBC commissioned a system capable of supporting its programs and spreading computer literacy. Acorn Computers won the BBC contract and would go on to deliver 1.5 million Micros, affectionately known as “Beebs”. It made a huge impact on education in Britain, setting many young learners on a path to a career in technology. We have 18 BBC Micros, all in working order and used as part of the museum’s teaching programme.

Gift: Keyring featuring a BBC Micro keyboard key.

Colossus valve

Sponsor level: Silver

Colossus refined earlier attempts to automate code-breaking; it was a programmable, digital computer built to crack the most advanced codes of the German military. Among its innovations was a single, paper-tape loop containing the intercepted message punched out as a series of holes that Colossus read at a rate of 5,000 characters per second. All Colossi were lost after the War and TNMOC houses the only working rebuild - constructed with the aid of original documents.

Gift: Museum fridge magnet OR keyring containing 5 hole paper tape used on our Colossus computer.

Harwell Dekatron/WITCH

Sponsor level: Silver

Recognised in 1973 by the Guinness Book of Records as “the world’s most durable computer”, our Harwell Dekatron/WITCH is a survivor. Developed to automate the hand calculations of people working out the maths for Britain’s first nuclear power stations, it enjoyed a second life in academia being used to teach computing, before it was retired and eventually consigned to storage. We rescued the Dekatron/WITCH and returned it to full working order in 2012, making this the world’s oldest operating digital computer.

Gift: Notebook showing a picture of the WITCH, made using 3.5 inch floppy disks.

Commodore PET

Sponsor level: Gold

Commodore International was an electronic calculator manufacturer who - faced with diminishing sales prospects - needed something new. Commodore in 1977 therefore introduced what would become an icon: The Commodore PET. With a 6502 processor, Basic in ROM, integrated screen, keyboard and cassette deck, this futuristic-looking system delivered everything needed in a home computer at that time.

Gift: A set of four coasters, each with a custom-printed image of the Commodore PET.


Six pack of Colossus valves

Sponsor level: Gold

Installed in banks of 2,500, thermionic valves were the key innovation in Colossus. They allowed this computer to perform the necessary switching speeds, in the volume required to perform the complex mathematical calculations needed to crack the German military’s most advanced encryption during World War II. You can see these valves in action as part of the world’s only Colossus rebuild at TNMOC. 

Gift: 3D-printed Colossus valve with colossus paper tape inside.

Apple II

Sponsor level: Gold

Before the iPhone, MacBooks - even before the ‘Mac’ - came the Apple II, the company’s first successful personal computer. Released in 1977, a year after Apple was founded, the Apple II put personal computing in the home, education market and businesses - the latter thanks to the powerful VisiCalc spreadsheet application. It offered a colour screen, attractive casing and expandability. Updated versions would continue to be developed and sold into the 1990s.   

Gift: A set of four coasters, each with a custom-printed image of the Apple II.


Bombe drum

Sponsor level: Gold

Alan Turing and Gordon Welchman built the Bombe to mechanise the task of cracking messages encrypted by the German’s Enigma machine. The device was capable of a potential 103 sextillion settings, with settings changed every 24 hours. Bombe checked approximately 17,500 character positions. Our working rebuild was achieved using parts re-manufactured from original drawings and by piecing together source documents.

Gift: A custom-made, Enigmatix encoding wheel made to look like a rotor


Full 903 cleaned up.jpg

Elliott 903

Sponsor level: Gold

The Elliott 903 from the lost and legendary Elliott Automation, represents a generation of computer that emerged around the mid-1960s from manufacturers trying to make computers affordable and practical for everyday use by “ordinary” users. Available in a range of configurations, the 903 was used for industrial and scientific applications and data processing by those in education, industry and design. Input and output was via hole-punched tape.

Gift: A set of four coasters, each with a custom-printed image of Elliott 903 and two with hole-punched tape.

World War II cryptography bundle

Sponsor level: Platinum

Cryptography didn’t stand still during World War II - nor did efforts to break the enemy’s communications. As the codes evolved, so did the mathematics and the machines to crack them. Our platinum-level, wartime cryptography bundle lets you sponsor our ongoing work on Colossus, Bombe, Tunny and Heath Robinson. Each of these  machines represents a distinct phase in the cryptography arms race and each performed a vital function in the interlinked process of cracking the crypto and deciphering the enemy’s messages. 

Gift: Colossus Mug and Bombe Notebook , made using 3.5 inch floppy disks


Modern electronic computing pack

Sponsor level: Platinum

From EDSAC, the first practical, general purpose, stored program electronic computer, to the PCs of the 1990s - we chart the story of modern electronic computing and how it shaped the way we work, learn and relax. As a Platinum sponsor you will fund the EDSAC rebuild project, the running and maintenance of the Harwell Dekatron/WITCH, Elliot 803 and 903, our Large Systems Gallery, and PCs both from the golden age of the 1980s, such as the BBC Micro, and the expansion of networked computing during the 1990s. 

Gift: Framed 60s printed circuit board OR a black Ones and Zeros mug
