Step 12 – Install the "Write" Jumper
Discussion: At this point, we need to connect one small jumper wire onto the back of the main board in order to provide
the new retrofit board with the CPU write memory control signal. The jumper connects pin 20 on the IC22 EPROM socket
to IC21 static RAM 6116 pin 21. The picture below is of the back of a MK1 main board. Use the picture below to identify
