This is slightly old news by now, but owners of older Haas machining centers are revolting  over lack of product support on older tools (like, 90s and aughts). I have some sympathy for Haas here, but I’m also aware that manufacturers of heavy equipment like Caterpillar and John Deere (note,  Deere has other big issues on maintainability ) keep huge libraries of old casting & forging tools so that they can support ancient equipment. Presumably we’ll eventually get to a steady state where control boards are seen the same way mechanical parts are; I wonder whether the end of Moore’s law, over which there has been so much hand-wringing, might at least bring some stability to the electronics market and give a little more heft to the argument that electronics are only end-of-life because nobody’s willing to pay for them to be resuscitated.
