The original machine is not - however... construction of a working machine was reconstructed in 2007.
Since an Abacus is technically a computer, I can only assume you mean the third binary electronic computer. This was called "Colossus Mark 1" and was developed in the UK to read encrypted German messages during World War II.The Colossus machines were the first programmable, digital, electronic, computing devices and went through several revisions so if you define a computer in this way, a Colossus machine would still have been the third computer device ever to be constructed.After World War Two all the blueprints and Colossus hardware were destroyed in the interests of National Security and it was not for many years that its designers would receive the credit they deserved for the world's first programmable electronic computer.

The Colossus was built using thermionic valves, thyratrons, relays and stepping switches.The Colossus Mark 1 used about 1600 valves and the Colossus Mark 2 used about 2400 valves. After the Colossus Mark 2 was in production and use the single Colossus Mark 1 was briefly shutdown and upgraded to a Colossus Mark 2. Five of the ten Colossus machines also had a device called the "gadget" that aided in a process called "rectangling", the number of additional valves added to each of these enhanced Colossus Mark 2 machines is unknown.
An "Old Computer" would literally be any computer that has become out of date. Which is almost literally, every computer that goes out of the factory. However, most people would consider anything older than Windows XP to be rather 'old'.colossus
