Peter is right, it is a "unique-to-Ford" 32k EPROM. Just to expand
on that a little more, when I say "unique-to-Ford", it was my
understanding that normal EPROM programmers could not be configured
to read/write them. Ford buy their EPROM programmers from Data-IO
with special adapters which are not available to the general
public, they are only available to Ford as are the devices
themselves. I also seem to recall that the EPROMs have more
little-tricks/differences inside than just non-standard power/GND
pins. The Ford M-Bus is a wierd and wonderful beast, it must have
been designed by committee ....... 

While consulting for Ford, I actually wrote the majority of the
EEC-iv software that runs the RS-Fiesta Turbo. Out of interest, what
are you trying to do ?
