I bought a DM42n calculator a while ago and it’s been a fun desk toy that I admittedly have little practical need for. I’ve since updated it to use the C47 system which is the most delightfully nerdy, ludicrously powerful calculator mankind’s ever schemed up. My kingdom for a printed manual, but still!
