I bought a SOFI SP8A and the SOIC8 SOP8 Flash Chip IC Test Clips Socket adapter to go with it. 1st is it possible to do read and write it with this setup and 2nd is there a tutorial on the process?
So if you would like to write a tutorial that would be great considering you are the third person to ask. It is the exact same process just with a different programmer and different software doing the footwork.

I got this programmer too it works great and easy but on macbooks i got a problem, i can't read the chip on board it gives me error, so i must unsolder the chip programe it and solder back,it's to much work.
why you can programme chips onboard with raspberry without problems and not with a (normally) programmer? i don't get it
bye the way i got sofi sp8A and sp16A Both the same problem
Well that stinks. Are you disconnecting the battery when you try to read the chip? How are you interfacing with the SOFI? I may order the new Raspberry Pi also just to be on the safe side. I wonder if the new PI would work OK.
One of the best things to remember is SLOW is SMOOTH and SMOOTH is FAST. You need to make damn sure the connection is solid and your commands are correct. Also when you have the clip connected grab a multi-meter and test the voltage running to the VCC pin on the chip. It has to fall within the range that is specified on your chips datasheet. This is usually about 3.3v minimum.
Well maybe i'm doing something wrong i'm not a pro,
yes i disconnect the battery, But i did not use the isp connector on the sofi because i did not know how to connect.
Maybe you have more experience with it and maybe it will work for you, then i will be glad if you make an tutorial for this programmer (-:
It will be more easy job with sofi then a raspberry to program eeprom chips
Maybe the clip is the issue. Most people say those SOC8 black clips are very low quality, but there are a blue ones called Pomani, or something like that. Those seem to be better.
