Sophia rev. C (DVI output)
This is an add-in board that goes under the GTIA in all Atari computers, including the 1088XEL or XLD. It consists of two boards: one board is inserted into the GTIA socket and the GTIA chip is inserted into the Sophia main board; the second board holds the DVI connector and is attached to the first by a ribbon cable (included).
NOTE 1: If your 8-bit is NOT socketed, you will have to de-solder the GTIA and install a 40 pin socket.
NOTE 2: If you are installing this in a regular Atari (400/800/XL/XE) OR a 1088XLD, you will either have to modify your case and/or let the connector hang out the back.
NOTE 3: If you are installing this in a 1088XEL, you will need a DVI compatible backplane (available for sale here or design your own).
