World Cup 90 by Tehkan (1990)

This is the oh so familiar single board pirate version. The pirate has no drum
synth and no fancy sliding background on the attract mode title screen. Other
than that it's the same game as the original. I also have Euro League on this
board which seems to be the same game but with European rather than world 
teams. No idea if this was also available as an original game...

 16K files were 27C128
 64K files were 27C512
128K files were 27C010

There was little in the way of reference designators, so I'll do my best...

Starting from the JAMMA connector at the top and working down.
A01      -> Sound Z80
A03, A02 -> Main Z80 No. 1 (A02 next to Z80)
A05, A04 -> Main Z80 No. 2 (A04 next to Z80)
A07, A06 -> Graphics pair 1
A09, A08 -> Graphics pair 2
A11, A10 -> Graphics pair 3
A21, A20 -> Graphics pair 4

A19 -> A12 -> Large block of graphics

On many boards I have seen, A19 -> A12 have been ROMS soldered to the board.
