I recently bought some NeXT hardware from the U.S. Some of it got damaged while in transit. In particular, the keyboard got smashed to smithereens (well, 5 or 6 pieces broke off). I've never had success in gluing plastics of this type before ... but, this being, even if only a keyboard, a rare and rather special NeXT item, I don't just want to chuck it away either. I think there are few enough pieces and they are in places which are not load bearing so that, provided a strong enough glue could be found, it should be possible to restore the keyboard so as to at least approximate its original state.

Any suggestions for a glue that would work - or is this a hopeless quest?

Another common problem is because of age the plastic on nonadb keyboards is becoming brittle and breaking loose ; if you have a separated corner that is what has happened . Solution There are seven screws that hold the back in place with a rubber gasket sandwiching the keypad to the front assembly. The seven female posts located on the front half sometimes one will break off. I just successfully used a smidge of superglue on one and gorilla glue on another broken post to fix the problem. I found it easiest when reassembling to hold the keyboard top gasket and bottom together with a firm grip 90 degrees in one hand rather than flat when screwing it back together with other hand. It keeps the gasket in place, I have not tried key capes yet .
Tomaz please pm me. I have quite a few packages I need to forward to you! Best regards Rob Blessin

What might be working (since I had some good experiences with it) is epoxy two component glue. There are different strengths available and some are made even to fit together special kinds of polymer. Some even sustain some flexibility when hardend.

I use shoe goo.
The bond is good enough for a keyboard and it's flexible enough not to break again with regular use of the key.
