While I've only been working with the Handy Board for a week or so, I
would also like to see several more outputs added. Perhaps some
combination such as 8 digital (CMOS) outputs, and 8 of the
dual-transistor types. If you could rig it up with jumpers so you
could select either 5v or 9v, that would be ideal. That would give
considerably more flexibility, if it's not too hard to implement.
If this is asking too much, even 8 additional CMOS outputs and 4
transistor would help a lot. So far, I've used up two of the
digital outputs, and I'm just getting started. It would also be
handy if additional instructions were added to IC to make it easier
to access the outs without having to do bit-masking.
