Claus and I made a ton of progress over the past day. In my post yesterday I had mentioned how Claus added some display code and the initial blue screen was being displayed successfully by FC64.
Claus kept on and added the timers which gave us the blinking cursor. Last night I hacked together a (very rough) keyboard implementation, which means the emulator now takes input from the user.
See for yourself at http://codeazur.com.br/stuff/fc64/ -- Flash Player 9 required.
You can now enter BASIC programs and have FC64 execute them. An example program that loops infinitely displaying "HELLO WORLD" is:
10 PRINT "HELLO WORLD"
20 GOTO 10
RUN
You can access the double quote by pressing shift and 2 (this is what the keyboard actually looks like). If you hit Escape, the program will abort.
There are definitely some things that are broken. Claus and I are currently brainstorming about how to best map keys - physically vs. logically, a mix of both, or fully configurable. The keyboard support that is in there now works for the most part, but some keys just don't register (and they won't until we come up with a better solution).
But hey, it works! Enjoy! :-)
By the way, we'll be entering this in the Flex Developer Derby in the hopes that it wins the "Just Freakin' Cool" category. Fingers crossed...

Love it! But I definitely vote for an option to use the keys in the configuration of a modern keyboard.

I think you might get all 6 of the prizes. And well deserved it would be.
Nice, nice, nice.
