Pacland by Namco (1984) (Benelux edition)

This is the Namco version as opposed to the Bally/Midway version. 
Bally have VTI mask PROMS and Namco have labled EPROMS. Also, the Namco PCB is
a much better quality than the Bally one (Namco has a gold plated edge 
connector with a green solder mask and white silk screen)

16K files were 27128
 8K files were 2764
PL-2 -> PL-5 were Fujitsu MB7132E PROMS
PL-1 was a Fujitsu MB7122E PROM

Board locations:-
PL5_01B -> 8B
PL5_02  -> 8D
PL1_03  -> 8E
PL1_04  -> 8F
PL1_05  -> 8H
PL1_06  -> 8J
