System 3
The Acorn System 3 added a floppy disk controller card, floppy disk drive, and disk operating system ROM, replacing the cassette interface card and cassette operating system of the System 2 machine.
The System 3 became the standard workhorse for development in the Acorn lab: the Acorn Atom has been called a cut-down version of the System 3; and it was based on the System 3 that much of the development work for the BBC micro was done.
A minimum configuration contained:
- A CPU card
- A 40×25 Teletext-standard VDU card
- 8K RAM with 4K BASIC ROM
- A floppy disk controller
- One 100K floppy disk drive
In 1982 this was being offered for £775, or £1075 with power supply, casing, and two further 8K RAM cards; plus, again, an additional £136 for a keyboard.

Famous quotes containing the word system:
“Fear, coercion, punishment, are the masculine remedies for moral weakness, but statistics show their failure for centuries. Why not change the system and try the education of the moral and intellectual faculties, cheerful surroundings, inspiring influences? Everything in our present system tends to lower the physical vitality, the self-respect, the moral tone, and to harden instead of reforming the criminal.”
—Elizabeth Cady Stanton (1815–1902)
