Hey there!

I'm using one of your adaptors:

h**p://www.jensma.de/upload/files/hW01Y6pL__DSC_0585.jpg

Recently the adapter behaves weird.

I want to put data like this on it:


AAA
BBB
CCC
DDD
EEE
FFF


My programmer ends up with an error. The eprom contains data like:


AAA
BBB
CCC
AAA
BBB


It kinda repeats the data at some point. The error pops up while writing a file to an 27C800 eprom, at adress 0x000202.

Any ideas what could be wrong?

Thanks in advance =)
