Clean and solid design, so easily customizable with the solver, great display...
Maybe Swissmicros could make a DM27 ?

I don't think so. Unless Thomas Okken first makes a free27, which I doubt he will make. The HP-27S ROM, like all pioneers, remains copyrighted by HP, which prevents to distribute an emulator with the ROM...
