Nice project!

Does this also use hacks around the PLA like EasyFlash?

Why not use pages of 8 / 16Ks too?

I had once a simpler ram extension idea employing the same concept in
below old project which was published in the Transactor. (But of
course with a bigger 512K or 1MB sram)

Sure this solution throws away the existing ram but it's easy to bank
in a whole 8k or 16k segment at once.

It would be nifty to have some external storage mechanism in the cart
too. It would be really cumbersome to load content into this
additional ram from the disk drive.
