Hi Jason,

It has been quiet from my side for some time... I found a few spare 
minutes to further investigate my GPS4. Playing with the various jumpers 
did bring some response but no final solution.

Next thing I did, I took out the EPROM and checked it with my 
Willem-programmer (a nice versatile cheap programmer (check Ebay)). I 
discoverd that the first addresses till $003000 are empty!

It would be nice, if you, or someone is willing to check with their 
EPROM. The BIN-file can be read with the Willem-software program 

Looking forward to your response!
