Let me show you.
Converting board for J61000
Converting board to DIP8
This board is really helpful for EFI-ROM Access at J6100 connector of
Apple MacBook LogicBoard.
See below case :
MacBook doesn't boot because of EFI-ROM.
Need to replace serial # after replacing LogicBoard.
Forgot your password after locked.
Diagnose EFI-ROM and SPI communication.
Must need this?
The answer is NO.
Actually, you can access EFI-ROM without converting board.
However, you'll more comfortable and easy to access if you have this.
See below case :
Don't need to remove EFI-ROM every working.
Don't need to solder jumper-wire on LogicBoard.
Don't need to disassemble LogicBoard.
*Some models require disassembly.
MacBook Pro Retina with TouchBar
Let me show you how to use.
This is also necessary.
The SPI Programmer.
But I think, you already have it.
Otherwise, you can buy on eBay or Aliexpress.
Start from $2

Do you want to use this on old model such as 2013 MacBook Air or Pro Retina?
It can possible if you use Add-On board.

FPC Cable 15cm
1 X 4 Pin Header
1 X 2 Pin Header
* LED and resistor are not included.
* NOTE *
If some SPI programmer doesn't work, you need to supply 3.3V to 'PP3V3_SUS' of the Logic Board.
That can't be solved by the limitation of the J6100 pin map. That is not a defect of the converting board.
As mentioned that, you must supply 3.3V to the 'PP3V3_SUS' of the Logic Board using a DC power supply.
