The early cartridges were made with a form of low exteaction force sockets
-- a kind of poor man's ZIF, designed to make it easier to extract the
ROMs. You've probably got those. You put a small screwdriver blade in,
against the bar, and twist (only when there's a chip in the socket!!)

It's called the Master Series Welcome Guide. No, I'm not parting with mine
just yet :-)

AFAIR, 2732s should work, 2764s certainly work, and then up to 27128 is
officially supported. You can use 27256s and *possibly* 27512s if you
program them appropriately.
