A CONTRIBUTION TO THE "SUPER GS PROJECT" Have you noticed that The ROM sockets in a GS 03 motherboard have an extra 4 holes beyond their 28-pin sockets? I have seen a 32-pin ROM in where the ordinary 1-Meg 28 pin ROM normally resides. There are 2, 4, and even 8Meg ROM's on 32-pin chips. How about putting ALL of system 6 (or whatever else) into ROM for fast access? There are all sorts of utilities which could fit into the (vast) excess ROM space. To allow a 32-pin chip into a ROM 03 GS, buy a (24-pin or 28-pin) WIDE socket at Radio Shack. Use a hacksaw blade or any fine-toothed saw to saw off a 4-pin socket from the end, 2 pins on each side. Smooth off and trim the jagged edge of your little 4-pin socket with a flat jewler's file (or emory board). Clear the 4 holes at the (notched) ends of the ROM sockets on the GS ROM 03 motherboard as follows. Clamp the motherboard gently but firmly in an upright positipon so you can apply the nozzle of a solder sucker on one side of a hole, and the tip of a hot soldering iron to the other side of the hole on the opposite face of the motherboard. Squeeze the bulb of the solder sucker and, holding its nozzle against the hole, melt the solder from the other side. Let go of the pressure on the rubber bulb but keep its nozzle against the hole. The result should be that the solder suckert "inhales" the liquid solder, freeing the hole. Carefully trim any excess solder from the margins of the hole with a "dry" but hot soldering iron tip. Position your 4-prong socket into the 4 holes, flush against the motherboard and flush against the 28-pin socket already in place. Brush the pins to be soldered with electrical (rosin) solder flux and solder into place filling, but not over-filling the holes you just emptied. Your GS ROM 03 is now ready for a 32-pin eprom. Such eproms (27C10, 27C20, and 27C40 are available from many places. I use Jameco and ask for a data sheet along with the chip for a pin-out to aid in its programming.) Most sincerely yours, Dr. H.
