Will Max support something bigger than 6116? I ordered a few cheap 32k sram chips in sdip that don't take much room... Even if we cant use the whole capacity.

As you know, the cartridge port on the Max is subtely different and you don't have the same select lines exposed so it seemed easiest to use the /exram line to gate the latch. Maybe you have an idea for how we can use alternative lines that exposed that will leave the /exram free for it's intended purpose?
