I was going to do the 20k or 32k mod on one of my boards, but the though of cutting some of the traces on Mike Willegal's beautiful Mimeo work would pain me ;), so I want to build a DRAM expansion card that can plug into the side. I have a bunch of mk4116 16k chips from an old Apple clone. Has anyone done this before? I could come up with my own schematics by studying the Apple I guide and the data sheets but if someone has it already would save me some work. I know I could use a static ram chip like the Replica I pretty easily, but actually want to do something that would be more period correct in design since I know the 4116 chips were released in 76-77.
