I was not able to find any useful DOS drivers for Roland RAP-10 card except this topic - http://www.verycomputer.com/47_33edfd7292704769_1.htm . These DOS drivers exists somewhere in the internet? Anyone know?
Are you sure this sound card (Roland RAP-10), does not support any Sound Blaster? I managed to find a special DOS driver for this card - TAPIRAPT.COM. It seems to me that the driver works as a Sound Blaster for this card.
