11  NOTE: Even though the MAME/MESS project has been adopting a non-commercial additional licensing clause, I do allow commercial usage of my portion of the code according to the plain terms of the GPL license (version 2 or later). This is useful if you happen to use my code in another project or in case the other MAME/MESS developers happen to drop the non-comercial clause completely. I suggest that other developers consider doing the same. --Felipe Sanches

23  There seems to be an eeprom or a realtime clock placed at U2 (DIP8):
24  pin1 -> 8031 pin 14 (T0: Timer 0 external input)
25  pin2 -> crystal at X2 (labeled 32.768)
26  pin3 -> ?
27  pin4 -> GND
28  pin5 -> ?
29  pin6 -> 8031 pin 5 (Port 1 bit 4)
30  pin7 -> 8031 pin 4 (Port 1 bit 3)
