The problem is that this is extra hardware that not every board will have right now but is definitely something one can add on his own.Right now I'm more looking for ideas on how to control the soft CPU without any extra hardware.
If you poll $C010 fast enough, you'll see the keycode change and the AKD high bit before the strobe sets the high bit of $C000. That might allow for "stealing" the keypress by continually resetting the strobe before the Apple's 6502 gets a chance to "see" it... (Of course, you have to keep watching AKD to detect repeated presses of the same key. ;-) Does the card support DMA access to (for example) video memory, or are you limited to VGA output? -michael ******** Note new website URL ******** NadaNet and AppleCrate II for Apple II parallel computing!
