In the images below is the setup for the following eeproms , these are only rough for now , the reason i am posting this is so people can see how these eeproms are connected when not done In Situe . Please note this was done for testing purposes to improve the NT software , as soon as i have time i will make a proper lead and give a more detailed tutorial on the specifics.

yeah i already made an adapter like this, i used some vero and my "proper" programmers adapter to rig something up.

what did you use for power? i had to rig up an external power source.

edit:

here are some pics of mine (yes, i know iphone camera sucks)

Nice setup you made there , i kind of abandoned this project as it seemed there was no interest in the Eeproms. But to answer your question , i too used an external power source , i contemplated using the power on the NT itself but figured i would end up doing more harm than good that way.

The speeds are amazing compared to the normal programmers . The problem with most things, are people in forums tend not to be willing to contribute , all they want to do is leech , so in waiting for people to come up with ideas on how to make a useful adapter etc, went down the pan , as it seemed as if i was the only person that was using it for programming Eeproms. Good to see you are making use out of it , by designing your own setup.

The speed for EEPROM is not optimized compare to other targets. I know for some larget EEPROM the speed can be important. I do not have a lot of target to test and at the time of development rely on Koevoet to test.

I think for larget EEPROM the speed can be 10 times faster because large EEPROM allow faster clock. The current code uses the same slow clock for all the EEPROMs.

Guys Don't let his post count fool you. Hes a very knowledgeable Person and Admin ot another Forum. Seams to Me He is Only Pointing out Yet another Good Use for the USBJTAG NT. While I use a Simple Serial Programmer to read and write to EEPROM's Its good to Know the USBJTAG NT Can Also Handle the Task.
