Hey folks!

Since I failed miserably with this adaptor... http://www.mcumall.com/forum/topic.asp?TOPIC_ID=4997

...I bought a MCUMall 16bit adaptor. Unfortunatly I still can't manage to burn the eprom :(

I attached some pictures:

I've got a wall wart connected with ~12V:

Any help is much appreciated :)

With the jumper next to the dipf and p1 connected, everything worked after re-erasing the eprom :)

Well, with the jumper set, the first bytes (aborting at 0x00E8BF right now) are written successfully then the process is aborted. Any ideas :(?

I connected P1 too, it's still failing.
