Interestingly, the man that inspired me to play with Acorns in the first place was an inventor at a company with its own foundary and machine shop. The kilns, and many of the machines used for casting/pressing, were all run by BBC B+ machines (later A3000s with expansion ports used). I think there are still two major kilns (we're talking thousand of tonnes of molten metal here) run by an A3000.
Oh, and it was all written in a mixture of BASIC and 6502/ARM. So maybe, just maybe, STD are onto something here.
