Hi Kip,

Yes, I would like to collaborate. :)

What are the designs you have so far?

I’d like to make what would presumably be the simplest type of upgrade first,
a single 512k static ram chip. I’ve just started to read up on how the GIME chip
MMU functionality handles memory. So far I can see it’s all broken up into 8k blocks
that are presented to the CPU based on registers in the GIME.

Do you have the details on how the address/data lines should interface to the GIME?
