There is nothing on the underside of the board. The card gives a yellow screen on another Amiga so its fried. The battery killed something.
My soak for tomorrow is to fire up DOpus and open the interface and just keep adding more stuff to RAM till the thing falls over. It'll either kick out at around 850K with DOpus and Workbench loaded or it'll carry on past 1MB.
So what'dya think...My money is on flipping out at around 850K. There is no way that computer has 1MB chip RAM. Maybe The memory is on the same bus so I guess you are right. I was going to pull the Gary but I gotta put it back in the motherboard or find another.
I have another one of these Power Computing GARY cards plus expansion but reading the guide for the Mega Chip there is always some board hacking that needs doing to Jumper 2 and 7A. I can't see if any of that was done. The previous guy has stuck every single chip down. I still can't work out the switch. MAYBE.. just a thought he took the A500 on his motorbike to Amiga Demo Parties and the chips kept popping out. Either that or he was a nutter. Gotta be some reason. There is also the possibility that there is a peice of the jigsaw missing like an A5000 or B5000, Spirit, Viper or Midget board that sat over everything and was stuck down. Who knows.
