Has anyone got a tape that will fit the 1987 denford triac pnc3. I really need to try one in this mill I have. It works beautifully and is without any signs of wear at at all, not even one chip could be found on it. I dont think it has ever been used. Im certain the tape drive would work if I had the right tape. Please let me know if anyone can help. All leads that I've found here have gone nowhere. Thanks
