JUMPER SETTINGS FOR ATARI TT RAM BOARD With the board placed in the TT and looking at it from the front, there are two rows of jumpers. There are 5 on the bottom and 1 on top. From this perspective each jumper can have 2 settings: Either on the lower two pins (D) or the upper two pins (U). (lower is closer to the front of the TT) 4 MEG SETTINGS Top Row: U Bottom Row: U,U,U,U,D 16 MEG SETTINGS Top Row: D Bottom Row: D,D,U,U,D If you have any other questions you can email me at G.ANDERSON42 on GEnie or garya@tenet.edu on Internet. The best people to contact though would be Carter Graphics in Utah. They have been an exceptionally good bunch to do business with. These settings are only for the Atari board as far as I know!!!
