Hi Bob Bybee has place his Polymorphic emulator on his web page. He was an editor for the PolyNews. The emulator runs on a PC in DOS mode. Most current machines can emulate the original faster than the original. He originally wrote the emulator for people migrating from the Polymorphic machines to PC's but wanted to keep the software that they were previously using on the Poly's. Many had ledger programs and Poly's BASIC was one of the better implementations. Anyway, it is all good fun: http://bybeeweb.com/pm.htm Enjoy Dwight PS Any specific questions about the commands, you can either ask him or me. He is much more expert than I am but I do have a working knowledge.
