I see, everyone seems to vote for #2. Not a bad choice at all.
Too bad I don't know how to design that unless I go get some
information. You seem to know this, maybe you could design the hardware?
I could help with the software, then.
BTW, just to test the idea I designed and built #1, and it seems to
work. It just lacks software (I used some simple test routines).
If someone is interested, I can post the schematics and my idea for a
protocol for it; as it now seems, it's not going to be the final design,
though, but maybe it will become a historical curiosity some day. ;)
It works without external batteries, so maybe it still could be used for
something...a remote control emulator like the HP calcs? :)
