That sounds *exactly* like a DigiRule 2 to me. https://bradsprojects.com/digirule2/ They were AU $28: https://www.tindie.com/products/bradsprojects/digirule2-the-8-bit-programmable-binary-ruler/ But it was a few years ago now: https://www.hackster.io/news/digirule-2-ruler-and-binary-computer-in-one-68b269af283f ... so now I guess you'd have to build your own. -- Liam Proven ~ Profile: https://about.me/liamproven Email: lpro...@cix.co.uk ~ gMail/gTalk/FB: lpro...@gmail.com Twitter/LinkedIn: lproven ~ Skype: liamproven UK: (+44) 7939-087884 ~ Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053 _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
