Acorn A4000

The Acorn A4000 was a slightly cheaper cut down A5000, with a shorter case, one expansion slot and an ARM250 processor.

Curiously, the machine had its floppy and hard drive fixed to the chassis with a wire clip which meant these could be quickly replaced without tools, whereas replacing the hard disk on the A5000 was a more fiddly operation requiring the expansion slot plane and the whole chassis holding the drives to be removed.

Many of the features (ARM250, VGA screen modes, RISC OS 3) of this model were implemented into the lower end A3010 and A3020 computers.

The keyboard was a much cheaper type more similar to a generic PC unit.
