There were some sweet machines other than women: an old Bugatti, a lean Farina coachwork on an American chassis, a Swallow, a type A40-AjK Mercedes and lots more.

Subsequent formalizations were framed as attempts to define " effective calculability " or " effective method "; those formalizations included the Gödel – Herbrand – Kleene recursive functions of 1930, 1934 and 1935, Alonzo Church's lambda calculus of 1936, Emil Post's " Formulation 1 " of 1936, and Alan Turing's Turing machines of 1936 – 7 and 1939.

Competing machines such as the Altair 8800 generally were programmed with front-mounted toggle switches and used indicator lights ( red LEDs, most commonly ) for output, and had to be extended with separate hardware to allow connection to a computer terminal or a teletypewriter machine.

Although Acorn were able to shrink substantially the same functionality as the BBC into just one chip, manufacturing problems meant that very few machines were available for the Christmas period — to the extent that some shops reported eight presales for every delivered machine.

There were also many popular games officially converted to the Electron from arcade machines ( including Crystal Castles, Tempest, Commando, Paperboy and Yie Ar Kung-Fu ) or other home computer systems ( including Impossible Mission, Jet Set Willy, The Way of the Exploding Fist, Tetris, The Last Ninja, Barbarian and SimCity ).

The flapping machines that he designed were either too small to generate sufficient lift, or too heavy for a human being to operate.

New machines were added to the network by plugging them and optionally giving them a name.

The NBP lists were examined and displayed by a program known as the Chooser which would display a list of machines on the local network, divided into classes such as file-servers and printers.

The system was slow by today's standards, but at the time the additional cost and complexity of networking on PC machines was such that it was common that Macs were the only networked personal computers in an office.

As long as the machines were synchronized, the mix would sound more-or-less normal, but if the operator placed his finger on the flange of one of the players ( hence " flanger "), that machine would slow down and its signal would fall out-of-phase with its partner, producing a phasing effect.

For example, automated DNA sequencing machines were the basis to complete human genome projects leading to the birth of genomics.

These machines were similar in technological terms to the 2600, but sold for much higher prices with associated higher profit margins.

Historically almost all early computers were accumulator machines ; and many microcontrollers still popular as of 2010 ( such as the 68HC12, the PICmicro, the 8051 and several others ) are basically accumulator machines.

Different magazines were published featuring programs for specific computers, though some BASIC programs were considered universal and could be used in machines running any variant of BASIC ( sometimes with minor adaptations ).

During the Second World War, Bletchley Park was the site of the United Kingdom's main decryption establishment, the Government Code and Cypher School ( GC & CS ), where ciphers and codes of several Axis countries were decrypted, most importantly the ciphers generated by the German Enigma and Lorenz machines.

Both of the two German electro-mechanical rotor machines whose signals were decrypted at Bletchley Park, Enigma and the Lorenz Cipher ', were virtually unbreakable if properly used.

All three architectures were considered mainframe class machines:

The architecture of these machines were similar: stack machines designed to be programmed in an extended Algol 60.

The machines were designed to execute COBOL efficiently.

During the early twentieth century, electro-mechanical machines were invented to do encryption and decryption using transposition, polyalphabetic substitution, and a kind of " additive " substitution.

Atari did what many of the other home computer companies did: they purchased the source code to the MOS 6502 version of Microsoft 8K BASIC, intending to port it to run on their new machines.

After visiting the McDonald brothers ' original store location in San Bernardino, California, the founders and owners ( Keith J. Kramer and his wife's uncle Matthew Burns ) purchased the rights to two pieces of equipment called " Insta " machines and opened their first restaurants, based around a cooking device called an Insta-Broiler.

ECRM, Compugraphic ( later purchased by Agfa ) and others rapidly followed suit with machines of their own.

In addition, tickets for travel via First Capital Connect between Gatwick Airport and East Croydon can, like Gatwick Express tickets, often be purchased in-flight on carriers such as easyJet, thus avoiding queues at the ticket machines in Gatwick Airport South Terminal after landing and clearing security.

A single Express class fare is £ 18. 00 online, £ 19. 00 at ticket offices and machines, and £ 24. 00 if purchased on board.

( Flight insurance could be routinely purchased in vending machines at airports into the 1980s ).

Commercial embroidery machines can be purchased with a set number of heads ( 1, 2, 3, 4, 6, 12, 15, or 18 ).

After Lombard began operations, Hornsby in England manufactured at least two full length " track steer " machines, and their patent was later purchased by Holt in 1913, allowing Holt to claim to be the " inventor " of the crawler tractor.

A management group, led by Gilbert G. Pollock, purchased Mylstar's pinball assets in October 1984 and continued the manufacture of pinball machines under a new company, Premier Technology.

Also, to augment the call-for-aid phones, there are now exit fare machines located inside of the fare gates, so that if a rider has purchased the wrong fare, they may pay the remaining fare to exit.
