How do I modify my ZipGS to accept the new “skinny” RAM chips?
With a little modification you can make a Zip with wide sockets accept both the wide (600 mil) and the newer 300 mil skinny 32k x 8 Static RAMs (SRAMs). Ground yourself then carefully pry out the static rams. Look at the socket and you will notice two or three horizontal bars holding both sides of the socket together (Picture D). Carefully snip those out (wire cutters work well for snipping plastic). This will expose a column of holes. Now, solder in half of a socket. Refer to Picture E below. Plug your skinny SRAMs into the left and center columns making sure the notch on the static ram is facing up– i.e. toward top edge of board. (Applying power with a chip incorrectly socketed could damage the chip.) _______ Added center strip Snip out | ___ ___________ Skinny RAMs plug in here | | | | notched end facing up.
