Homebrewed HP48 cards
Message #1 Posted by David Griffith on 8 Jan 2012, 8:13 p.m.

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.
