Followed instructions for the GAL22v10B version but have issues...

Hi @mikulski-lab

I followed the instructions:

1. Socketed the extra RAM right hand bank sockets and put 8 x 4164 chips in them
2. Programmed the 22V10B GAL with the appropriate JED file from your github folder for the 22V10B, connected the pins on the chips as in your image with wire
3. Placed in the EMMU socket (U34) with the 1st 2 pins on each side of the 22V10B hanging off of the front of the socket.

The 65XE starts fine, but when I load some 130XE games, I get a message either telling me that I need the extra 64K to start the game, or the game requires a 130XE machine.

Do I need to use the 74LS95 at U35 too? I didn't think if using the 22V10 that I needed it.

I would appreciate any help you can give?

Many thanks,

Mark.
