Prologue
Prologue
• Our APPLE II has a speaker and can make some simple sound and CPU must handle every t
ics for tone, Due to these difficulties, new sound card appeared name of Mocking board I, I
I, A,C but, so long time ago and discontinued.
During long time, It was my the only sound card for APPLE II and I can’t find another sound
card Of course I can have a Passport card but it isn’t sound card. It is just MIDI interface.
After research both FM chip , AY3- 8910 and 6522 functions, I could design new sound card
it is the SD Music+.
It isn’ t just new sound card with new chip sets. If we need new program or new game(?) , it
would be useless that’s why It is compatible as our classic mocking board but, much better
musical instruments.
• The SD Music+ integrated with new technologies to drive FM chips(YM2413).
• You can use this card on APPLE II, II+, / / e even IIGS but, as we know, Mocking board does
n’t work well with APPLE IIGS and have same compatible issue.
• It can produce 9 channels of sound and 8 channels are used for mocking board channel an
d the last one is used for noise emulation.
• But mocking board have limitations and not very good to drive YM2413, For drive all functio
ns of Ym2413 sound chip, It provide ‘Native mode’ with this mode, you can control YM2413
almost of all functions and there are no limitations as mocking board compatible mode. For
example you can use 5 percussion sounds and can add one user music instruments and ca
n change to another music instruments.
• If you are good at the programming on APPLE II, You can make good music player or music
converter.
