What System 80B changed: three new boards

System 80B added three boards: an alphanumeric display that takes over from the four- and seven-digit displays of System 80A, a new power supply in place of the 80A supply, and a piggyback board on the control board that holds the program in place of the U2/U3 ROMs. It can show text messages, has fuller bookkeeping and self test, lets high scorers enter initials and shows the top five scores in attract mode.
