I feel kind of out of place here, but I was going to post when the thread just started but didn't get around to it right away and so I guess I'll go ahead anyway (and apologies if this doesn't work right). There's nothing special at all about most of this and even the last is not very special. It's just my stuff. So, #1 is my oldest active computer (Dell Inspiron 3668) which has no network connection and is running a several-years-old Slackware.
#2 is my new Dell ECS1250 in the corner running Slack-current/Windows 11 (oem) and, temporarily stealing its keyboard space, my HP 17by1061st (I think) laptop running Slack-current, Windows 11 (oem 10), and... FreeBSD 15.0!
#3 is the stuff under my feet: in the left, a c.1998 Compaq Evo which sounds like a jet taking off even when it's not doing anything (note the pads on the "side" where it's convertible from a tower into a pizza box); at the center, a c. 2001 HP Pavilion 510n; and, on the right, a Dell something. They would all boot but I'm not using them at the moment.
Finally, #4 is the keyboard and mouse of my IBM 350-P100 with the computer itself wrapped up behind it. The bag the computer is in is taped up, so I didn't feel like getting it out, but it looks good. (Not
this good, but good.) I can't remember if it still runs but I may try it again someday. I used to have many more but I got rid of all the unused ones (at the time) but this one.
