Dear Charles, I saw your ad on line. We have 7 or 8 860s, with spare parts for all. There were 2 versions, one with a Pl printer where the orange print button was pushed downwardly, to operate the printer; and 2) a HY-TYPE II printer, where the orange printer button was pushed from front to back to start the printer. If you have this latter version, with the very thick cable from the controller to the printer, then the printer is a HY TYPE II, a rock solid machine, like a battleship. These have a few quirks. Sometimes, the pwr. sup. burps, and you lose the boot-up. I was unable to fix this. However, if you disconnect the printer when you do your composing, backing-up, and so forth, the decreased load (printer not drawing current) will not cause this burp to occur. At least that is what we found. Hope you can get yours working. Let me know how you are doing. Thanks. Ken Lehmann, Fairfield, CT
