Snaps are okay for a short time if you can access the service manual to see where they are. Slide the spudger in the wrong place and you'll break a snap, ending up with a case that sags in one spot. So /design for manufacture/ can be counter to /design for repair/. The original Apple Macintosh was one of the first /design for manufacture/ computers. It required the dealer-only "case cracker" tool - a long Torx T15 bit with a spudger lever on the end: https://retrocomputing.stackexchange.com/a/118/439 - that told the story that Users did not belong inside the case*. Apple's previous computers invited you inside - the Apple II's top just lifted off without tools. Right to Repair is important. I'm slightly disappointed by the general reaction on this list. We'll spent lifetimes fiddling with software configs to keep it running against all odds, but hardware gets short shrift. I know that processing power and storage improvements have made it poor business practice to get sentimental about keeping older computers running, but some curiosity over how repair and replace is a good thing. We can't live on a growing mountain of e-waste, after all. Stewart *: the Macintosh had a CRT inside and thus hilariously fatal voltages for the unwary. It could be said Apple were only doing the right thing keeping Users out. But other computers had built-in CRTs with only the usual warnings and mounting screws. One example would be the Commodore SX-64, a device clearly designed for confusion. The SX-64 appears to be a random collection of boards held together by ... another random collection of boards and little else. --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk
