I'm gonna have to buy a few eproms and I remember reading the intro article about it. Let me just make certain that I am correct in my thinking.

a 27C128A-150 programs faster than a 27C128A-220 correct? Thats the only difference?

These are the correct part numbers for my 165 ECM right? Just making sure that I am getting the right ones as I have been having a lot of trouble with my equipment and I think my chip is the culprit.

A simple yes or no will do. Thanks.

 

are you setting the checksum to 04000?

 

Its a 16K chip...

04000 would be the end...

 

yes...

may want to look into using 29C256 EEproms and one of Craig's adapters.. will really make things easier and faster.

 

I'll look into it. I have read the article and it looks interesting. Whats the cost again $70?

 

The Difference is the read access time. the lower the number the faster it is capable of supplying the data. I don't think it is much of an issue in this application.
