That solution didn't work for me, unfortunately (maybe the EPROM was too
slow after all). I had to change my prommer hard- and software so that it
could handle 150ns CMOS EPROMs. Now everything works fine.

BTW, you write that you've used an 8k image. We tried to recompile the
code but came up with something around 8700 bytes. What did you do exactly
to get such a small image size?
