Hi friends,


I'm testing SD MIDI][+ final board.

In this time, I applied DC filter and OPAMP buffer for clean sound.

Now it works very good.



I'm testing other functions and will start to sell for local fans.


I've recorded two songs. Please listen it :)



And, This song recorded from PC MIDI to APPLE IIe & SD MIDI][+ card.

You can remember this song if you were really game mania in 386 era.. :D



Thank you very much.

SD MIDI ][ Plus

◆ SD Music card / 2016.11.08 20:31

Dear Friends,


SD MIDI ][ Plus card is going to complete.

This MIDI card is compatible to The Passport hence, You can play it on Ultima 5 and some other.



Now, I'm adding new features in this MIDI card.


1) You can insert MIDI Sound Module

If you install the MIDI Sound Module, It would work as Perfect MIDI Sound Card. Not just MIDI interface. 

2) It has MIDI Bridge mode 

It would act as an extra MIDI Sound Module. You can connect MIDI cable and it would generate Sound.

3) It would have few I/O ports.

I'm preparing 4 I/O Ports to ON/OFF (TTL Level).


I've tested the 2) Bridge mode


MIDI from PC to APPLE 2 and played on MIDI Sound Module.


Maybe, I could start to sell this SD MIDI][ Plus card from end of Nov.

I will let post here and eBay when It started.


Thank you,

Ian Kim

SD MIDI][+ card

◆ SD Music card / 2016.10.04 12:21

Dear Friends and APPLE II fans,


I've ordered PCB for SD MIDI][+ card.

It is similar as previous one but, as you expected on my products It added useful features,

1) It allow additional sound module, so MIDI card could be called as sound card.

2) It allow to MIDI IN Sound play ; It means that you can connect MIDI cable to MIDI IN of this SD MIDI][+ card, then It play sound as the external MIDI module.

I hope to like this MIDI card and those features on your APPLE ][.


I could show when I received the new PCB then could say some more for you.


Regards;

Ian Kim

Hi friends,


Today, I've tested Mockingboard 4c(socket type) on APPLE //e.

To do it, I removed 65C02 CPU and pull flat cable to the Mockingboard 4c.

It was little complicated and I had to use Proto type not selling one.

Anyway, I could hear sound of mockingboard as it is on Slot#4.


This purpose is for the testing for APPLE //c plus and Laser128 system which couldn't have Mockingboard on Slot#4.

Those type of APPLE II can't use Mockingboard 4c but some of fans, wants to use it on their //c plus and Laser128.

Due to some of internal structure are not the same as APPLE //c, I couldn't say would work on there.

and I have to test it on //c and Laser128.

Now, I'm sure my design worked on just APPLE //e. :)
