    Aww man, a pretty neat video came up on my YT feed, I watched part of it last night, went to watch the rest over lunch, and one of the things the creator tested a network connection with on an old Windows 2000 box was fucking 4chan.

    I've heard a couple people argue that some of the boards are still good but to be honest I'm just not sure I can take the chance that someone who still goes there isn't a complete fuckwad. The odds just aren't great.

      currently seeing what OSes my 2004 laptop can run. also wanna port my favorite games to old consoles, so I'm learning C and 6502 assembly

      here's a photo I took weeks ago of my laptop running (modern Linux distros hate my laptop)

      see you round! i'll probably just be lurking

              Well .. that went sideways. Despite many attempts, I have yet to find a 286 - or a 386sx for that matter - that will boot the NetBSD floppies without failing in some way or other. I'm not yet certain (perhaps someone here knows?), but there may be instructions missing from the various 486SLC and 486DLC CPU variants that my ugprade modules have. Or there are other bugs that I have not been able to figure out.

              Anyway, I've reduced my ambitions ever so slightly, and am now in the process of installing NetBSD (-CURRENT) on what is essentially a 386SX-class machine: 16-bit bus, 24-bit addressing, 16MB RAM, and nearly as unpleasantly slow as the 286 I had planned to use. It is however equipped with an IBM-branded 486SLC, which is from the Blue Lightning series. This one definitely has a full 486 instruction set. More hardware details will follow when I've completed the build (and installation).

              Meanwhile, the obligatory screenshot from the installer. Note the ETA for simply unpacking base.tgz ..

              Screenshot from installer. Shows base.txz being extracted, at a speed of 110 KB/s. ETA given is about 30 minutes, which turned out to be relatively accurate.

                    Findings at my parents' house, part 3: Two AlphaStations.
                    They have SCSI disks of different sizes, and the last time I turned them on (2008), they were working perfectly.
                    They heated the room wonderfully, and the fans were strong enough to move the pictures on the wall 😆
                    I haven't turned them on again, but they should still have NetBSD installed.

                    The image shows two stacked computer units with gray exteriors. Both units have a prominent "digital" logo in red and a sticker indicating "ALPHA GENERATION" on one of the devices. The computers are from from the era of older, high-performance computing systems, part of DEC's (Digital Equipment Corporation) Alpha architecture. The units are placed on a tiled floor with some plastic wrapping and papers visible on top of the devices.

                      And it lives! Apparently I'm officially operating a Motherboard Bakery! :)
                      Now I need to get it properly configured and tested with DOS, then I can move on to the next steps - which involve the CPU upgrade, and assuming that works, creating actual, physical floppies.

So let me know at @ltning@anduin.net if you have problems receiving/reading my posts. I've made some tweaks but it will be unavoidably detained for a while following each post, my apologies for that..)

                            I'd like to maybe get some hardware I can run old (early 90's to very early 2000's) OSes/software on. I've got emulators but it's not quite the same. Looked at pixelx86, which look great but are very expensive with todays exchange rates. Are there other x86 hardware that doesn't entail building it from scratch?

                            Getting actual vintage hw is an option, of course, but it seems to be getting somewhat scarce.
