This is new SD DISK II Emulator plus testing version.

I'm testing it on  APPLE IIe in that time

Emulate as two HDD with unlimited HDD image replace capability.

Emulate as tow FDD (DISKII) with unlimited HDD image replace capability.

Used Angled connector for LCD Dial controller.

Change seldom using serial pins to upper location.

Still ready for Bluetooth serial dongle.


Tested on APPLE ][+ FDD emulation works

Tested on APPLE //e HDD and FDD emulation works

Tested on APPLE IIGS HDD and FDD emulation works


It works but, It has slight different compare to 5V CPLD version.

Stability little different not very good on my testing.

It rarely error about 1% while reading.

I will try to make it as perfect as previous testing version.

Keep watching it.

It is almost finished.

Hi friends,


This is new version of SD DISK II Emulator for APPLE2 computer.



This version changed components and optimized for less soldering error.

The total chips counts are lessen for less complication. (I really hard to make previous version)

ROM changed to another type (PLCC) and it would safer even send it by the POST.

Other small chips optimized into CPLD so, simpler and less time consume to make it.

LED changed to surface type; it looks better.

Connector for Dial was changed angle; it wouldn't interfere to other neighbor board in slot.

BIOS Switch Omitted; Automatic ON and OFF.


It works on


APPLE ][ & APPLE ][ plus (previous version had FDD write issue but, It works good now)

APPLE II (APPLE 2e normal version)

APPLE //e (APPLE 2e enhanced and platinum)

APPLE IIGS


No configuration or mode changed required for all APPLE II 

Just Insert it in slot#6 and connect dial controller..

Then Turn it ON and select your favorite DISK image file for your favor.

It would be announced on eBay about 3 weeks later.


Previous version owner still can use newer firmware without change.

I will work for it.


Thanks for waiting

Ian Kim
