    Posting and boosting this certainly put the box under some duress.. Changed ssl_ecdh_curve from secp521r1:secp384r1; to X25519:prime256v1; now; let's see if that helps.

    Those hardware specs are delightful (and it says a lot about @grunfink's work that snac is svelte enough to run in such a constrained environment; I can't fathom attempting to run full Mastodon on such specs)

                [Edit - fixed attachment]

                I've said somewhere I want to run NetBSD on a . Now obviously that's not actually possible, but I should be able to do the next best thing - run it on a 286 upgraded to a 486SLC!

                But wait, most 286es only support 4MB RAM, although the ol' chum of a chip supports a whopping 16MB. So I have to find a motherboard that can do this.

                Thing is, I already have one. See picture. But it's currently occupied doing very important Enterprisy stuff - it runs IBM OS/2 1.3 Extended Edition..but at least I know what I need!

                  So as usual, its eBay to the rescue. Found a board just like it, except there's good news and bad news: the good news is the CPU is socketed on this one, making the upgrade job a lot easier.

                  The bad news? See picture.

                    I'm a bit of a n00b at this, but I have salvaged a couple of boards before using vinegar and a toothbrush, so I'm trying my luck with that. After applying the vinegar and watching, hearing and smelling it sizzling, I dunk the affected part thoroughly for a few minutes...

                    Kitchen paper dunked in 12% vinegar, placed on the affected part of the motherboard to allow the vinegar to do its magic without disappearing into thin air.

                      And I know one should not apply regular water to electronics, but I'm trusting Oslo Waterworks to supply me with nice, clean water from the tap. It comes at high pressure to boot, so I can quickly get rid of all the vinegar to prevent it from slowly eating through everything. As long as I dry it properly and quickly, it should be fine, I'm told.

                      I said I was baking - It was not a randomly chosen term.

                        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.

                              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.

                                  I had on another 286 for a while, and there's some 16-bit "port" of Linux that is not as old as it should be. And of course the venerable OS/2 1.x, and a few actual variants as you point out. I didn't know about V6on286, that's a beautiful little nugget, thank you!

                                  All of those things are absolutely wonderful and make many of todays software developers look ... spoiled? What I want, however - and what I love doing - is making this old hardware do stuff its makers never dreamt of, things that are as far removed from their time as possible. That's why I will, if permits, run bleeding edge BSD on a 286-on-486steroids, and why I run web+ftp+irc servers (yes, multitaskign) on one 286 and multiple BBS nodes on a 386 - like one used to do, of course.

                                  I cannot state often enough how amazing it is that there's still software developed today that will work under such constraints.

                                          I haven't tried either, and I don't think I will. I'm already using 20MB swap when what you see in the screenshot is running. Netsurf is painfully slow even on a dual Pentium Pro, and it coredumps if I enable the JS engine. I haven't even tried Dillo for a long time, but without SSE2 and whatnot I don't really expect it to even start...

                                          When it comes to browsers, I've come to realise they're complex operating systems in themselves and there is no way for them to function on anything but a pretty modern computer. Case in point; @bob82@anduin.net and I installed NetBSD on their ~2010 Macbook Pro today, and Firefox was slow as molasses and coredumped repeatedly. Fairly sure it's due to missing instructions or whatnot. Might research more later :)

                                                I had to build my own kernel since the default kernel simply needs too much RAM. But once USB and a couple of other niceties were removed, it ran fine with the binaries from the i386 release.

                                                  Most of them can do more than they announce. It's like OS/2 2.11.. IBM said it can SMP across 64 CPUs but they could only test with 32 as that was the best hardware they had at the time :D

                                                  Yesterday I found a 486 board in my collection that boots and happily deals with 256MB of EDO RAM! The speed is hare-raising :D

                                                    You must let me know when you do. All modern Unixes I know dropped 386 support a while ago :(

                                                      The latest mTCP for DOS is available!

                                                      This version includes some changes to improve TCP reliability on long running (but idle) connections, black & white Sixel graphics in Telnet, a Telnet emulation bug fix, and other small fixes sprinkled around.

                                                      The source code to NetDrive (network attached storage) is also published now - enjoy reading an unholy mix of x86 assembly code talking to Golang over UDP!

                                                        I hate this ...

                                                        I found a really small bug in Telnet, but it's irritating. I don't want to go through the hassle of spinning an entire new update so I just patched the Zip files that I have posted at my site.

                                                        If you downloaded mTCP recently (more than 20 minutes ago) please grab it again. Otherwise, live with my terrible bug that throws the Telnet session into Sixel graphics mode without reason. ;-0 (Pressing a key gets past it, but like I said it is annoying.)

                                                        My apologies ...

                                                        Is the telnet emulation issue related to "cls" from some BBSes just giving a weird character instead of actually clearing the screen? :)

The mainboard is mounted horizontally in the upper half, which is transparent. Seen are various expansion cards and the back of the CPU card itself.
