Been toying around with Windows again. I find it hilarious that Windows 10 takes Windows 7 drivers for an Intel GMA950 just fine but does everything short of completely refusing Windows 8.1 drivers for a Radeon HD4650.
One odd thing about the GMA950 on 10 is that it immediately tries to rollback ("update") to the basic video driver, but if you turn off Windows Update-delivered driver updates (something I usually do anyway, if I want special drivers for something I'll install them myself darn it) it keeps the Intel driver and works completely fine. No "display driver has stopped responding" malarchy that you get with older NT6.x nVidia drivers. A trade-off is that OpenGL, while it technically works is a total slideshow. OpenArena, a game which should play just fine even on something as bad as a GMA950, is a total slideshow even in the menu. Direct3D works as you'd expect it to, if a bit slow because it's a GMA. Universal Windows Apps work fine. The UI is accelerated as it should be, with a slight stutter because (again) it's a slow GMA.
For a mid-2000s IGP, it's not a terrible hunk of crap. I could easily find worse (VIA's S3 UniChrome is completely god-awful but still manages to have Vista-era WDDM drivers that work in 7+). But at the same time I'm kind of left wishing for more. YouTube's flash player oddly runs like a slideshow while HTML5 video is actually watchable. What a weird twist. Usually for everything I own it's the exact opposite.
My friend gave me an old rubber dome Model M that he'd been hanging onto. I cleaned it and (after letting it dry for days while I thought that I had broken it) it works fine. Copyright date on the outside is 1994, production date on the inside is 2/3/95. Even as a rubber dome it's got pretty good tactile response. He thought he'd broken it when he unplugged it from a running machine (from what I understand it was an accident).
