Re: [CAD_CAM_EDM_DRO] Re: FAILLING MEMORY ON MY CNC LATHE

An eprom 'burner' is also a reader. Several reads (incredibly simple) will
either repeat
(meaning the data is repeatable, and >likely< correct, or you'll get several
different files,
(which indicates the data in the chips cannot be recovered)
Likely the data is not protected, so a reader/burner will be able to read,
store to a file,
you can insert new eproms, and burn the saved file, yielding new chips.
I use Needham electronics EMP-20, maybe 200$US. The chip ID you stated
doesnt sound very exotic, and unless it's a dinosaur, available from DigiKey
(google it, they carry burner's too).
