MTDV Pin 3 + 8 vdc
Notes
The LXMC-3 Board has gone through a modification. The older version of the board accepted
a 28 pin EPROM at the Q13 socket location. The newer version of the board accepts a 32 pin
masked ROM. It will also accept the 28 pin EPROM. No jumper changes are necessary. If a
28 pin EPROM is installed on the 32 pin Q13 socket, the four unused pins will be located
at the top.
