I received this last night and it DID work for a few moments after I added the yellow rubber band - it was loading a program on my NEC PC-6001. Then it ate the tape. Thankfully I did not trust it with my good tape and it was just a junk tape. It has some sort of soft but not soft press button tape control system. I'm not sure how it works, but it does odd things. You can't hit STOP when REW or FF, but you can turn it off and then the STOP will take. There is a solenoid, but I have no idea what it does although it does seem to help facilitate the STOP somehow. I am attaching a picture and I put a red box around a movable part that has a long metal spring to another movable part that is attached the pcb. I think maybe it is attached to an optical sensor. If I try to press stop during FF or REV and then I activate that red box item, the solenoid will fire thereafter and the stop will then work. What I don't understand is should there be something going on on the bottom of that metal part in the red box? There was nothing attached to the end of it to activate it or move it. There looks like a nylon thing towards the top that might push it, but I sure don't see any movement in that part when I try to push on it manually. Some of the other nylon parts are very stiff like the grease has long dried up on them, so I am debating trying to tear it down, clean the parts, and relube them with some new grease, and hope I can get it back together. Looking for any tips on that. Also, I can see what the solenoid does. It is attached to a vertical metal pin that seemed like it was going through to the tape section, but it doesn't. I suspect it must actuate some other part of the mechanism. This is a NEC PC-6082 aka DR-320, but I can't find a service manual for it anywhere.
