Quick: DarkSound by ByteBoosters

The Apple IIgshave GREAT audio capabilities with it’s Ensoniq 5503 DOC – chip but there’s no connectors in the logic board for stereo output for speakers. So the DarkSound-card resolves that problem with simple, single board with connector to the logic board itself taking the signal and outputs it to external speakers/headphones or amplifier in Stereo.

The pin settings in the card you can use are as of:
*HIGH – for non-amplifed speakers (direct 8ohm, 1.5mm plug)
*LOW – for headphones or amplified speakers (1.5mm plug)
*LINE – for external aplifer / home stereo-system (3.5mm plug)

The card itself is not slot dependent, as you can install it to any slot and it will maintain the internal slot/port settings.

It also features as digizer as it have input for the signal to be digized with software.

darksound_connected_side_small
Connector attached to logic board . It’s a bit tight fight with the Apple IIgs 8MBRAM/ROM-card (a2heaven.com) but it did fit there just barely however.

darksound_connector_small
Bit tight but fits.

oma_kaiuttimetI attached the card to crappy-old-Creative 2.0 speakers but they work just ok for time being.

ByteBoosters also produce other products for Apple IIGS. Available is also 4MB and 8MB RAM-expansion cards. Both are tiny and very reasonably priced.

I got few pairs of ECHO Sound Synthesizer -card speakers awhile ago and started to look for the interface card as well as one did not come with them.

Luckily i was donated pair of cards  (thanks Will!)
