The Multi I/O Board, 2007, gives 2 8 bit bi-directional ports with 4 handshaking lines, a 6522 VIA,, a true RS232 serial port, a 6551 ACIA, with speeds up to 19,200 BAUD, and a 8K EEPROM programmer to store data or programs. There is a socket to add your own Speakjet voice chip that works in conjunction with the serial port to make your Replica 1 or Apple 1 speak!
