Your question was answered at post #5. I don't get what the problem is now.
Sorry, I did not know that urjaman was a dev, or had a devboard plus keymat, and so was able to authoratively answer the question. Now that I know that I can take it as the "informed/experienced" advice that I asked for and not the potentially fallible "AFAIK" that it seemed to be presented as.
After all, in post #2 I was definitively told that the keyboard accepts 3 presses at once. Should I assume that is also correct, even though it contradicts what you have previously said? This is why I was asking for the experienced answers from devs, OP ones or thrid-parties like Pickle or whoever has been working on BBC Emulation. because they should know, and be able to give a simple clear and accurate response. Thankyou for letting me know that urjaman is a dev, I can give that user more credence in future.
urjaman - my apologies for not taking your word as being trustworthy. My apologies
