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

Hi Friends,


I would like to add PO image format support on SD DISKII Plus.

In fact, the PO format is almost similar as 'DSK' format. 

and Just rename PO file to DSK, It would work.

It just has different sector order for prodos but, DOS3.3 also can read it.

IBM PC HDD using this idea as the interleave.

Anyway, I add converter function in it.

It works now and will include into new release firmware version.


Thank you;

Ian Kim

Hi, Friends,


I trying to make MSX External SLOT on APMSX card.

It took too long time to make it work.

Hardly found some error on the board and fixed.

Also needed to adjust circuits on CPLD as MSX one.


Finally I have working screen as under.

It is just game screen but, this game is from ROM pack not data loading from APPLE //e.

It has some stability issue with external ROM. I'm working on it now.


If I didn't plan to make a external SLOT on APMSX, I could complete it but, It took long time for ultimate MSX card in APPLE II.


Keep watching it..


Thanks;

Ian Kim
