hi. I have a high speed that i am trying to use a 11A board in. When i turn it on all three LED's light and stay lit.
I have tried earthshaker roms and it boots. I have tried the board in a game and it works with earthshaker roms. I know the rom sizes are diffrent so I'm guessing the jumpers need changed or I need to double or 4x the image on the rom.
Ant help would be great.
Also need a hinge for the head box.
thanks

There are no jumper changes needed if you use High Speed Roms in an 11A or B board. The CPU does not have a 7 digit display so naturally you don't have a good diagnostic code. Naturally it will not blink because the program expects
a 7 digit display connected to the PIA outputs. So should just work even if the Leds stay lit.

Your right. I was testing it on the bench and when three lights came on I thought there was a problem.
so i put it in the game to see what it would do and holly crap it works. Is it worth it to go back and put the seven digit display
on the board. I haven't look at the schematic to see what all I would need. thank's again
