There are two almost identical versions supporting two commonly needed pinouts:
'''M4ROM_TANDY''' is only for TANDY 100, 102, & 200, same as Teeprom.
'''M4ROM_27256''' is for everything else, Same as Meeprom. (TANDY 600, Epson PX-4 & PX-8, Kyotronic KC-85)
'''M4ROM_27256''' is for everything else, same as Meeprom. (TANDY 600, Epson PX-4 & PX-8, Kyotronic KC-85)
