Hi, Friends,


If you don't know what is the SD Music card, 

Please watch this video and compare Mockingboard with this FM sound quality.


Another version of SD Music card is testing now.


From this version, It works perfect with APPLE ][+.

Previous version had some timing issue on APPLE ][+ so, some APPLE ][+ clone works so, I recommended APPLE //e.

APPLE ][+ and APPLE //e doesn't have same on expansion slot.

To discover it, I used a CPLD and now works perfect APPLE ][+ and //e. ( IIgs technical issue is the same as mocking board) 

This new version have same sound character but, it has nice function.

I will introduce it again.

Please wait for the SD Music card again and enjoy nice music programing even on APPLE ][+.


Thank you.

Ian Kim

Dear friends,


I developed the SD Music card to enhance old mockingboard of APPLE II.

In fact, I love this approach and sound quality.

In that version,

I replaced all electrolytic capacitors to tantalum capacitors for better sound quality and life.

And used RC filter on output AMP and some more improved.


But, It has compatibility issue following part's LOT#. It means that some chips works on some model with some software running.

In fact, After made this board, I've tested it on my APPLE //e and ][+ with SKYFOX and Ultima 4,5 before to ship. All fine then I sent it.

It works fine on APPLE //e even IIGS with Mockingboard patch.

But, I found it didn't work some software and some of APPLE ][+ model.


I really having hard time to find this cause...

It is happen because of the 6522 timing doesn't match well on APPLE II with 6502 CPU.

With some more research, I could find good way to overcome this issue and quickly applied on new PCB for SD Music card.

Sample card ordered and waiting for this.

On the CPLD testing, It works perfect on my APPLE //e and ][+ with all softwares.

and will test some of APPLE ][+ clones..

Please wait for some weeks for new board.

I will post when I have new board with testing results.


** NOTICE **

If you are not happy with your old version of SD Music card due to compatible issue, I will replace your card to new one. 

Please ask me the address and send your card with sure way.

When I received it, I will send new board for you. 


* I will test all arrived board, 

it if it failed to work with some another reason, It will be charged some costs,

Good working conditioned board will be replaced without return shipping charge.


Thank you very much;

Ian Kim

Hi friends,


I have final commercial PCB as below.

I'm soldering boards and have to ship it to enjoy together.

I will put some on eBay for international fans or you can contact me direct for purchasing it.



Thank you very much.

Here are some recorded sound.


MIDI Bridge mode 


Sound from Ultima 5 game.



** NOTICE **


SD MIDI Plus card had MIDI INPUT technical issue, 

If you purchased it before 24th Jan 2017, Your card may have MIDI IN issue with some of sequencer.  

(It doesn't have problem on playing Music on Ultima V)

In fact, it may avoid MIDI input error if you make a sequencer but, I recently acquire sequencer sofware the Master Tracks, It didn't work with it.

I've updated firmware and works fine.

Please contact any time to me by email(quick09@gmail.com) for free update service.

Anyway, I'm looking for good way for international previous buyer.


Thank you

Ian Kim
