No, the picture still shows my original version of the adaptor. I think I 
will adapt the instructions and pictures the moment I sell a PCB according 
to your layout :)

I don't need this for sure, because my Eprommer can read 2332 and 2364 ROMs 
directly without an adaptor.

What do you mean? In-system programming doesn't work at all, because there 
is no R/W line, and you need a 32kB window to the flash memory. So you need 
a flash programmer device, which can be my 6502 socket based device, or any 
other commercial programmer.
