Just cleaned out mt garage, closet, and attic. No clue why I kept every single box of anything electronic/tech based in the last ten years. I just tossed boxes for phones I haven't had in years, old CPU and heat sync boxes, boxes for 100mbps nics, old modems I don't have anymore. I've never needed any of these and have brought them with me through too many house moves.
Of course it is. It's fun to rebuild the computer of your youth, and run old games on periodically correct hardware.
Yes. !retrocomputing@lemmy.sdf.org is a good community. SDF.org is worth looking at, as the community there predates the internet.
