Dumping my first EPROM

[Paul Berger]

I would convert it to a binary image if you could and then look at it 
with a binary editor.  Most binary editors I have seen show the data in 
hex and also have an eye catcher on the right with the ASCII equivalent 
to the code points.   Trying to find strings in S-records would be a bit 
painful.
