I have some old functioning Apples and Macs still around from the late 1980s and early 1990s. I haven't turned them on in ages. At some point I will probably have to toss them. I also have some ancient Apple ][ computer with something like 8kb of memory, and the last time I started it up was about a decade ago. I had forgotten that there were computers with such little memory, but maybe that was because the TRS-80 had more.
My excuse for keeping these around was that I still had files from using them. Not sure the soft or hard floppies still all work. The TRS-80 used to have me running things from a tape recorder IIRC.
