I've had this IIc since college many moons ago. It still works but somehow the up arrow key cap has broken off as you see in the picture. I did, at one point, think I could just order a new switch, even if it wouldn't be the original type, and key cap, but I've found the key caps seem to come in different shades? The one I'd ordered seemed more white where as mine is more on the beige side. Perhaps it's also the 40 years age... Ideally I could find the same switch type and key cap that matches, but I'm starting to think this is unrealistic. This makes me want to somehow use the key cap that I have so that that one key isn't a different color. I was thinking of trying to glue it with something - epoxy, super glue, ... but was thinking that someone here might either have a good / better idea based on experience of options or if not what glue should I use. Thanks.
