We are happy to introduce the new Resound jr OPL3!
This card is based on the Resound 2 OPL3 card. This card uses the Yamaha YMF262 / OPL3 IC and YAC512 DAC to produce stereo output. It maintains compatibility with the Adlib card or OPL2 for all of your favorite DOS games. In order to install this card on your PCjr, you either need a Jr IDE Rev B or a TexElec jr Expansion Board with a free expansion header.
The Resound jr has a fixed IO address of 388h, like the original Adlib. It is designed to be low cost, easy to plug in and use.
The Resound jr outputs a line-level audio signal, via a built-in 3.5mm audio jack or a 3-pin external audio-header. The header may be used to connect an external audio jack on your sidecar if you prefer. An audio amplifier and speakers are required.

About the Chipset and Drivers
This card uses the famous Yamaha OPL3 chipset, used by many popular sound cards in the late 1980’s and early 1990’s. No emulation, it uses a real Yamaha YMF262 IC to do the work. The OPL3 is backwards compatible with the OPL2, so any game or application written to use an Adlib sound card will also work. Please note, this card will not playback wav/digital files, it is an FM synthesis card only. The OPL3 is the sole provider of sound.
