    Looks like z88dk's rs232 library does include the spectrum, if1 and +3.

    Didn't think it did when I last looked but apparently I was wrong.

    To be honest it's probably your ULA, which means you need a new If1.

    If it turns out to be the ULA, perhaps you could sell it to Stephan? You can send it to me and I'll check the ULA and remove it if it's ok, then fit the working ULA to Stephan's IF1 and send it back to him?

    Actually, scrub that.

    I just looked at the schematic and the IF1 uses a totally non standard pinout anyway. You'll definitely need a special adapter cable.

    Paul Farrow is a master of RS232 and he will also help you with any questions or projects you might have. For the IF1 you don't need to add another cable. You just need one, wired right (I think). :-)
