[Coco] Help with dumping various EPROMS

[Bill Nobel]

Hi Ron, Although Art’s comment will work, but it will miss the vectors from $FFF0 to $FFFF which are the key vectors for power up etc..  I use a method of reading ROMS from my eprom burner which is a TL866CS, nice little unit.  It reads just about anything.
