Yes, I'd been thinking about this and flicking through various catalogues - the only problem is that most connectors from place like RS and Maplin seem horrendously expensive. Anyway, I'll progress the design and then experiment with fitting it to my SAM. > Do you intend to supply the PCB or the completed interface. There's one chip that costs about a tenner in single quantities, or about six pounds in 25+ quantities. And it's from a place that charges a fair bit for postage and packaging - so for individuals to build their own would be pretty expensive (plus they'll need a PIC programmer). Also, I want to make sure that I can shift 25 units if I go ahead and make the investment. Perhaps, then, the best thing for me to do would be to finish the Speccy interface too, to increase the chance of shifting all 25 chips, and selling the SAM version as a complete unit or in kit form. I'll still post the circuit on a web page somewhere, but realistically it won't be economical for anyone to build just one for themself. Andy
