Meyco Games, unknown PCB, 1981
NOTE TO WHOEVER IS MAME DEVELOPER FOR THIS DRIVER: This is obviously part of a multiple board set.
The other PCB board(s) were unfound. If/when the game is identified,
could you please let me know what it is?
Dumper notes:
-Board is approximately 16.5"x14.25", with no daughterboards or satellite add-on boards.
-Board has 8 pin connector and 50 pin connector with no keying pins (see diagram)
-Board has an 20.000MHz crystal @ C4 (see diagram below).
-No dip switchs or sound chips on this board.
-Board has 32 uPD411 RAM chips.
-The 40 pin CPU is missing, Guru feels it will be an 8080 CPU.
-Dump consists of:
--6x2516 @ K3, K4, K5, K6, K7, K8.
