There is still a VM list and some one on their might remember... Do you know I can't remember the details either! There were multiple ways to interact.

It was a specialist padded cell environment. The user names were local to VM Share.

Re: How did VMSHARE user interface work?
Thank you Dave, your name was one that I had recognized in the archives! Understanding that it was more of a separate program and interface helps me get a better picture, the CONTACT MEMO you mentioned includes a lot of useful hints as to the interface.

Re: The TRS-80 Journey Continues
Another question for the masters here. I just tried to revive my Model III. More than half the keys don't work anymore. What is the conventional wisdom on cleaning these old TRS-80 keyboards? Is compressed air usually enough? Can I spray the switches with something like DeOxit safely? I expect when I go to revive my Model I's they are likely to be in the same state. bill

Of course the rubber wears. Cleaning,trying to re-surface the rubber, etc, makes only a temporary repair, but it's better than nothing. I started by pulling the keycaps off. Then I desolded all the switches from the PCB (it sounds a worse job than it is!). Took the PCB off, then unclipped the switches from the metal frame. The switches do come apart by unclippng the 2 halves of the housing. I cleaned the metal contacts with propan-2-ol, lightly rubbed the rubber on fine wet-n-dry paper and rubbed a soft pencil -- the softest I could get, a 6B I think -- on the face of the pad. Put the switch back together and measured the resistance when it was pressed. Not that the input circuit on the CPU board of these machines is quite high resistance, so a switch that has a resistance of, say 1k ohms will work fine. In the end I got it down to having 3 or 4 that were a bit dubious, needing harder-than-normal pressure or not working every time. Those I put in the numeric keypad area of the keyboard, I could easily live without that... Incdentally old Model1 machines have the metal contact keyboards, same contacts as the DEC VT52, VT100, the HP85, etc, the TI99/4A etc. Those are a lote more reliable. -tony > bill > >

RE: The TRS-80 Journey Continues
I had dysfunctional switches on a heating system timer. The trade advice since replacements were unobtanium was open them up and clean the contacts with switch cleaner. The contacts were two "gold" plated pads bridged by pressing down conductive plastic with a textured finish : same design as the keyboards. The cotton buds lifted a lot of black "tarnish" (probably airborne contaminants) from the contacts. Went from a few working, a few intermittent and some totally dead, to all 16 working all the time. Have to see if they last another 12 years before failing. I infer that cleaning off the contaminants is 95% of the solution. I doubt the solvent used is especially critical.
