The Acorn RiscPC

One of the main features of the Acorn RiscPC is its generous expandability - including its case. The basic RiscPC case consists of:

• 4 cm high base layer – contains the motherboard
• 6.5 cm high slice – contains two front-accessible drive bays (5.25" and 3.5") and two expansion card bays
• lid

More than one slice can be fitted to the case, giving it an virtually unlimited capacity. The layers are fixed together by a innovative system - 4 bolts hold it together (two inside and two outside) - and are locked/unlocked by just a quarter-turn by hand so that no tools are necessary to open the case - this is an enthusiast's computer. The bolts can be secured with padlocks.

The RiscPC Rocketship

Someone at Acorn decided to take advantage of this expandability, and took it upon themselves to build a rocketship with 8 slices and an in-built toaster.

A single-slice RiscPC

At the Olympia Acorn World (1996), Acorn demonstrated their second rocketship Risc PC. This one had 10 slices and an array of gadgets including a working pizza oven and remote controlled sink as the pictures below show.
