All I did was provide the necessary voltages and a little "glue" map the onboard UART into the $DE00 space. Probably the biggest problem with interfacing to a Sound Blaster card would be writing the software. - Mike Naberezny (firstname.lastname@example.org) - This message was sent through the cbm-hackers mailing list.
