New SD DISK emulator tunning
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.
