I would like to read what is in the old EPROMs in my machine. They
contain the ladder programming for the machine. I cannot get a copy of
this ladder from Miyano, who made the lathe and wrote the ladder. Is
there a way to read what is programmed in these EPROMs? I guess I
should ask if there is a way I can read what is in them. I know what a
ladder looks like and can read one but I don't know if one can be read
from a device just by downloading and using a text reader to see what
is there.

It would be doubtful if you could. The eprom will give a bunch of
hexidecimal numbers. You would need a program that could convert that
to the ladder.

That's what I thought. Maybe I can get FANUC or MIYANO to read some
EPROMs and provide me with a ladder printout if I send the devices to
them.
