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.
