Acorn A4000

The Acorn AGC10 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.
