    Hi there, just looked at your interesting blog entry regarding repair of a TRS-80 model 1. I would be interested to know about your experiences repairing the key. I have a model-1 keyboard on which 4 keys are currently non operational and I was about to tackle them. Are the individual key’s easy to dismantle? What did you replace the contacts with or were you able to clean up the original contacts?

    ragards, Rob

    Hi Rob,

    Not easy to repair these keys, the better way is replace it with a spare parts, from other keyboard for example (with the same mechanism).

    Hello, recently acquired a TRS-80 model 1…works well apart from the space bar not working at all. Previous owner says it was working fine, but when I received it (well packed Aussie Post) space bar doesn’t work.

    How would I determine that the keyswitch itself is faulty. I’ll also need to put a meter on the ribbon cable to ensure that there are no issues there…they certainly look a bit frail. All other keys work fine.

    Appreciate your help.

    Regards
    Michael
