MEGA Audio with Apple /// in ][ emulation-modes:

Based on preview copy of the MEGA Audio-card!

a3_setup_ma_desk
As there’s different ways to emulate Apple II with the Apple ///, i went ahead and tested the new MEGA Audio-card by a2heaven.com with the Apple /// and it’s native built-in Apple ][ 48k RAM and the Titan //e 128k RAM-emulation modes. The regular Mockingboard card is known to work in built-in emulation mode (so far it physicly fits inside) but i wanted to know if the MEGA Audio would work as well and it’s all emulated built-in, audio-cards: Mockingboard, A.L.F. and S.A.M.

I configured the card to use slot 1 and for testing, also slot 4 as Mockingboard, the Titan cards occupy the Slots 2 and 3 in Apple /// the stock, 256k model had all slots free.

I tried also installing the actual Mockingboard cards i have, but no luck.. because:

Mockingboard (reactivemicro) does not physically fit inside. The Apple /// area where the cards are inserted is actually pretty small (shorter). The cards can be taller, but have to be shorter in order to fit inside.

Mockingbogard Tube (a2heaven.com) does fit, but the RCA-connectors it have in the end of the card, touch the bottom of the slot opening hole, and prevent the card been pressed down in the slot. Some riser card could be used but at the moment i didn’t have one.

The Mockingboard from Ian Kim (apple2.net) does fit but i do not have it anymore but it’s been proven to work.

Internal speaker – is it forwarded to the external speakers?
-Apple II 48k (NO), Apple //e 128k (NO)

Accessing the menu?
-Apple II 48k (YES), Apple //e 128k (YES)

Slot settings for the different cards?
-Apple II 48k (YES), Apple //e 128k (YES)

Equalizer working?
-Apple II 48k (YES), Apple //e 128k (YES)

Card led settings?
-Apple II 48k (YES), Apple //e 128k (YES)

So the MEGA Audio-card works quite well with the /// – just the Mockingboard-emulation is not working. It would be nice to have it with Titan //e emulation. Maybe later there will be MEGA Audio Pro?
