Sorry to have to say this but it sounds like a
bad burn job on your roms (EProms) or they were
corrupted somehow.
You have done everything you can and they still
don't work.
Where did you buy them, were they shipped across
country borders ?
They may have been subjected to a magnet or UV
light which would probably corrupt or even wipe them.
:boohoo:
