Programming questions

Vince: Is there any way for code to safely detect the A2MP3 card? The code I'm working on needs to be able to find it without asking the user for the slot number.

The a2mp3 uses a 6551 ACIA like in the super serial card. I would poke a byte in the 6551 register and see if you get the desired result. For example, I would set the baud rate, then verifiy the baud rate. Set the bit rate, verify it is 8. Just a way off the top of my head thinking. I'll look more at the 6551 registers to see if you set one, a different register will give you a different value.

By the way, :)
