Homebrewed HP48 cards - David Griffith - 01-08-2012

Some time ago I found pages on making homebrewed HP48 cards (typically battery-backed RAM), but I can't find them anymore. Does anyone here know anything helpful on that subject?

There are a couple of designs available at hpcalc.org under HP48 -> Documentation -> Miscellaneous.
