Q. Me and my friends are into C, Pascal and 68000 assembler on the BBC, Electron, Oric, Spectrum, Commodore 64, Vic 20 and Atari. Our manager has given us two weeks to list our programs. Can you tell us how?

A. Mere mortals are under the impression that the only way you can run 68000 code is on a 68000 machine, but those in the know can run it on as little as a couple of old radiogram valves with just a few small hardware modifications.

We wonder if the method you used involved the rusty nail and the brandy butter, or whether you've sussed out something of your own?

At present you can run C only on the Dragon 64 (under OS9), the Commodore 64 (from Aztec) and (soon) the Spectrum (Hisoft). The only home computer you can run 68000 code on is the QL, and although that uses the 68008, the instruction sets are the same.
