DIY 16MB 30-Pin FPM SIMMs: Supercharge Your Vintage Hardware!

This is a follow-up of my 4MB SIMM project. At that time, I created an altered version of SIMM PCBs that integrated a mod to operate EDO memory chips in FPM. A simple switch toggled between both modes and allowed me to get my 386 board to 32MB of system memory. Today, we are pushing the board to the limit! I will attempt to create 16MB SIMMs - the maximum supported capacity of 30-pin SIMMs. Let's see if I will be successful to get my 386 to 64 or even 128MB!
