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.
