The joystick routine has errors in it, which I fixed and now it works as both joystick and keyboard which the original would not do. http://www.mdawson.net/vic20chrome/vic20.php?load=http://www.mdawson.net/files/gobble/gobble.prg Just problems with Zeros and Ohs, and you need to ...

I noticed the first error is because you put zeros instead of oh's in an OR.
The second was an incomplete line.

Yeh, nothing under IE9, even then IE9 doesn't support sound. Your best bet is latest Chrome, then Firefox (remember to turn off firebug if you have it installed). As for speed, I am slowly working on a faster version, I think I should be able to get at least a 5x speed up. What sort of laptop do you...

So the plan I was going to use was an attempt at hardware assisted line drawing. By wiring (T1 ->) T2 -> shift register and other combinations you can use it as a bit shifter for the line (assuming you turn off interrupts). I think I was down to 17ish cycles a pixel ignoring setup. The thing is you ...

Actually you may be able to get a little more precision doing DAC by... 1/ Assuming the four channels outputs when off sum to a relative value of 1.8 (4*0.45) once they reach the volume section, that would give us 0->27 in steps of 1.8 2/ Setting two channels 180 degrees out of phase then switching ...
