Arcade Monitor Madness
Here is a handy hint for those of you who have arcade machines. Depending upon yor game board and your monitor orientation you might find the game is displayed upside down.
One solution is to locate the meaning of all those DIP switches on the board and hope one will flip the picture back up the right way.
Unfortunately, many of the earlier (read classic) arcade game boards don’t have a DIP switch to do this. So you are left to pull out these clumsy hunks of a monitor and frame and rotate them… which honestly is a real pain… and can subtract from your 8-bit enjoyment.
However, I found this handy hint…
Warning - arcade monitors carry lethal (yes it can kill you) voltages. So before you do any of this remember to turn the damn thing off!
There is a 4 wire connector that goes from the picture tube to the main circuit board. Its highlighted in the picture. Now this is for real, i can confirm it, because i just did it. Cut the connector itself with pliers or sidecutters between the 2nd and 3rd pins. This will give you two separate connectors. Swap the first pair around so that wire 2 goes on pin 1 and wire 1 goes on pin. Do the same with the second pair so that wire 4 goes on pin 3 and wire 3 goes on pin 4.
Turn everything back on and she’ll be up the right way.
