Tbh I wouldn't really call this 'retro', but seeing as Mint Linux did, I'll consider it as such 😮
Knocking together a PC for my youngest son. He's hogging his brother's Core2Duo system to play Super Mario via emulators and is getting a surprising amount of fun out of Minecraft too. So to keep my sanity (fighting children...) I'm building him a build. My in-laws recently returned an Athlon64 X2 system as it was too slow for them, mainly due to the 2006-vintavge WD1600JS HDD in it. Before I got a chance to fix that, they bought a new Core i3 system, so I have a decent 'modern' system to burn.
It's a Biostar MCP6PM M2+ with Athlon 64 X2 3800+ "Windsor' CPU with 4GB RAM and a Radeon HD4350 passive low-profile GPU. FIne for any modern OS I'd say... unfortunately Linux Mint says 'nope', as does Lubuntu 19.04. Eventually I managed to boot Ubuntu 18.04LTS, so that's what it's running now. Looks great on the 2004-vintage Eizo L768 monitor I found at the thrift store last week. Peripherals are definitely retro too, SGI Granite PS/2 keyboard and MS Trackball Explorer - but those are for my retro-setup. Still need to see what the little one gets, but probably some Logitech MX-based keyboard (his brother has a Compaq-branded G80-1800 with MX black) and a Kensington or Logitech trackball. He knows and likes the Orbit Scroll, so I'll give him that. That means I need a new device for the HTPC in the living room, but I have enough pointing devices, so no problem there 😉
Crazy that a 2010 motherboard with 2006 CPU should be so 'retro' that modern stuff doesn't boot, but maybe I'm just getting old. Now, time to boot up that old 486 😜
