External SD DISK][ Emulator is working

I'm developing for SD DISK][ Emulator for external DISK][ cable. 

Target support machine is the APPLE IIc cause it doesn't have APPLE2 IO Slot.

Now, It is working and doing reading and writing properly even format is working.

I'm running test as below.

1)Boot DOS33

2)Load hello test file and SAVE it again.

3)Read count and ++ and write it

4)Loop it

More than 1,400 time running without R/W error. 

It is still on testing..

Thanks
