Although it is technically possible to do it - I remember accidentally putting 
a ROM backwards into my EPROM programmer once and it coped fine without 
damaging anything (luckily - said programmer is an intelligent Z80-based 
combined PAL/EPROM unit with about ten sockets on it and *masses* of circuitry 
inside; I wouldn't fancy fixing it if it went wrong!)
