Quick plug first. If the BBC Master's year 2000 problem is still annoying you the only known ROM-based Y2K fix is still available from me: Doomsday costs £10 inclusive of manual, ROM and postage!

OK, that's not so difficult.

Crikey! What were they making it out of? Gold, I hope.

Here's the parts you'll need from Maplin Electronics:

   2  x  HH36P 6-pin chassis DIN socket   @ £0.55 each
   1  x  HH29G 6-pin plug                 @ £0.49
   2m of XR26D 6 core screened cable      @ £0.79 per metre
   1  x  BZ72P Small black box            @ £1.65 each
   1  x  AR35Q 4 pole changeover switch   @ £0.95

By my reckoning, that's less than £6 of parts so I'd imagine a tenner's about the right price for a built one!
