i didn't see a topic so you can post about old computers in here, i think that might be fun pics, videos, marketing, personal projects, anything goes as long as it's not too modern (90s is pushing it unless it's a sparc/alpha/etc box) kicking it off with the most beautiful homebrew build i've ever seen, one of three this guy owns pictured is a completely homemade wire-wrapped pdp11/05:   he also has a homebrew lsi11 and pdp8, both also wire-wrapped, and the pdp8 is used to build microcode for the 11/05

on mastodon rn a bunch of gentle nerds with old Macs, featuring former forums poster Kaleboo, are setting up an AppleTalk network over a WAN and they're having a nice time sending each other StuffIt files and printing MacPaint drawings  https://mastodon.social/@paulrickards/112045487877724638

dunno how many people are familiar with the pidp11/70 (scale reproduction of a pdp11/70 with a pi or fpga inside) but the maker is wrapping up his pdp10 recreation project and just launched a new site to go with https://obsolescence.dev/pidp10.html looks

I picked it up years and years ago for free, or nearly so. Had no idea they'd end up being one of the most desirable of the old macintoshes. I also have the PPC upgrade and DOS compatibility card that work with it for extra fun.

for old computers in my apartment, I've got a MicroVAX 3100/40 under my desk that had some capacitor in the PSU let out the magic smoke. it's a neat little box, not particularly speedy (something like 3 VUPs) but you can run netbsd on it and telnet in just fine. also a mostly working mac classic ii. most recent acquisition is an IBM PS/2 Model 50, one of the weirder machines here as it's a 286 machine with a 1.44 MB floppy drive... and an MCA bus instead of ISA. everything in it checks out okay except the riser board for connecting the floppy controller to the proprietary card sockets that IBM used on the PS/2 floppies of this era has an exploded tantalum on the 12VDC rail, so the BIOS will detect the floppy drive but can't power on the motor. of course, since the CMOS is configured by booting from a floppy, and I had to replace the CMOS battery wiping the NVRAM in the process, I can't boot it from the hard drive until I fix this riser board. needless to say there's a bunch of soldering in my future

ADINSX posted:God that color palette, I should get a keyboard with those colors DEC were really, really good at colors and design in general imo, i love the colors of the PDP12 and various PDP8 models, there are so many good examples in their history  VAXen are really cool machines! i have a handful atm, a 3100/40 like yourself (actually my first vintage machine), a vaxstation 3100/76 that needs repair, and a microVAX II boardset (KA630 CPU + 16MB of RAM) that i swap in and out of the BA23 box that holds my PDP11/83. mine typically run VMS because i have an interest in operating system design and engineering (though i'm not smart enough to express it in code), though. i do appreciate that the netBSD port is still active though! the PDP11 runs... well, RSX11M+! i'm actually working on getting graphics on the latter two VAXen, i have a VCB02 controller and the boards for eight plane color graphics, but i'm missing a few interconnect cables and a bulkhead connector thing known as a cabkit, basically just gives me actual physical ports to plug stuff into instead of having to run DIY cables out the back of the chassis, which is uglier. the VAXstation, i'm just waiting for a good price on an SPX graphics board. i have a decent number of older computers at this point but those are really the most interesting, the others are oddities or really only interesting to other sickos who are way too deep into this stuff.
