Simple Stereo Upgrade


Simple Stereo Upgrade

Not yet available

 

     It all has begun long time ago, when Chuck Steinman of DataQue created this set of plans for building stereo sound by installing a second Pokey chip inside the best 8-bit computer ever. Once installed, the second channel has all its addresses 16 bytes set higher in the memory ($D210 - $D21F). Since then, dozens of sounds and demos that support this upgrade have been published. Most of these programs were made in Poland, but a few sound-demos were also made in other countries. The most popular programs (in my opinion, of course) playing msx in stereo are Yooomp! and Numen.
