Did you ever think about having a Bluetooth connection to your CPC, e.g. to transfer your data or DSK images directly from or to it? Of course it is possible and it is very simple to realise that, plus: you can use all the tools, which already work with the CPC Booster+. I already use this setup for nearly a year and found the time time to document it. You can find the documentation in the articles section of this page.
That’s definitevely one of the most wonderful and useful hardware projects of the last years!!!
