You need to burn the 27SF512 with offsets see this link: http://static.moates.net/manuals/FlashAndBurn.pdf

I'm not sure I completely understand your question.

Moates.net offers a chip emulator called the Ostrich 2.0 http://www.moates.net/ostrich-20-the-new-breed-p-169.html which replaces the chip. ...

The 27SF512 chip is an Electronically Erasable Program Read Only Memory (EEPROM) chip. Most chip programmers can usually erase the 27SF512 chip in about second maybe even less time than that! ...

Yes

There is just enough room for either a 24 pin DIP socket with a chip, or a modified 28 pin ZIF socket with a chip to fit under the cover. A modified 28 pin ZIF will fit a 24 pin DIP socket, but...

I think that will work. I'm not in favor of the dip socket that has been selected, not positive locking enough for my standards.

I'm thinking I might have miss communicated which pins get cut. Only pins 1, 2, 27, and 28 are cut. From what I can see in the posted pic, pin 26 appears cut?

The (Zero Insertion Force) ZIF...

The bottom 24 pins do not get cut.

I like using leaded solder. The ECM has leaded solder also. I use a fine tip soldering iron.

I used some 22 ~ 24 AWG solid copper wire that is "tin" plated I found in a dumpers a few years ago....

I've used the Moates adapter and a DIP socket, which has a clearance problem. Soldering the Moates adapter directly to the board corrects the clearance problem. The modified ZIF allows for easy...

If you add the cost of a ZIF Socket, Moates Burn2, and one 27SF512 chip, the cost is about $100 to do chips yourself. The software TurnerPro is freeware. I can't think of a less expensive route for...

I'm going to skip over a mountain of details about using a 27SF512 Flash Chip in a '7747 ECM. I'm only going to focus on the actual hardware conversion. Soldering is required! The zif socket is a...
