In the days when BYTE still was worth reading it contained a note that
pointed out that the LC rom was a standard less than $5.- item in which the
polarity of the chip select had been reversed.  The author also pointed out
that somewhere near the rom socket there was an unused inverter, so a bent
pin and a few small wires did the trick.

Sorry I don't remember what issue, but would guess within the first five or
so years after the first issue.  Good luck.
