It's fairly rare that I get a full set-up all in one go, but here is the A5000 which came complete with computer, keyboard, mouse and monitor.

I have two of these type of monitor now and the power switch is dodgy on both of them. The problem is cleverly circumvented here with the insertion of a small block of wood.

When Acorn brought ought the A5000, the main box was designed to make it look more like a desktop PC. I think this is a shame as I always thought that the earlier Archimedes machines look rather distinctive. A side-effect of the redesign was that the power switch was moved to the front for the first time. Being so near the floppy disc drive, it wasn't impossible to accidentally turn the machine off when changing discs. Here a bit of blue cardboard sellotaped onto the front nattily eliminates the possibility.
