The Machine Room is Back!
This is the recovered Machine Room from 2005. Please don't expect wonders. The look and feel of this site is nine years old, and so is its code. Some of the functionality has been recovered while the rest of the site is modernised and restructured. Watch this space!

The File 2 was a mainframe computer with 72 bits per word. It used excess-3 binary coded decimal arithmetic with 6 bits per digit, allowing 11 digit signed numbers. Instructions were 72 bits long. It was an upgraded implementation of the File Computer.

Core memory of 1740 words was added (a field upgrade on a File 1). Although it is not entirely a fair comparison, because this was a word oriented decimal machine, this is about 15.3 KiB .

Peripheral Memory
General data storage magnetic drum memory (average access time 17 milliseconds) provided 15,000 words per drum. With the maximum of 10 drums, (although it is not entirely a fair comparison, because this was a word oriented decimal machine) this is equivalent to 1.29 MiB of drum memory.(help us)
1 to 10 General data storage magnetic drum units, 1 Tape collating processor, 1 to 10 "input-output devices".

An "input/output device" consisted of an inquiry typewriter, a punched card unit (for either 80 or 90 column cards), a paper tape unit, a printer, and optionally a magnetic tape drive. They could operate interactively or do offline transaction processing independent of the computer.
