The 1701 was the
world
first PROM that could be reprogrammed. By using
an ultra violet light it was possible to erase the data
stored.
Early versions without C prefix and grey traces are
extremely rare. They
are one of the "most wanted" chips in any collections.
Only a few pieces
are known in perfect condition.
