Bought Retro City Rampage on Steam and copied Retro City Rampage 486 (DOS AND Windows 3.1 Prototype) to my 486 and started running them. Actually quite like the experience.
Have been spending some time pricing upgrade CPU and Cache RAM for the 486 - I have a FIC 486 PVT, am thinking about tossing some 128kx8 and a 32Kx8 Tag in there to bump it up from 0KB to 512KB (Maxxed out) Cache. I've also been looking for a good case to put the beast in so my 286 has a home again but have been going through quite the conundrum about it...looking at AMD 486 DX4-100, but I prefer the Intel Versions because of my experiences with one (let's just say, DIablo says it NEEDS a Pentium, I got Diablo and Postal to both run okay-enough on a 486 DX4-100).
Meanwhile, I have a Gateway 2000 Pentium 1 system that's almost all original (P100, 64MB, SCSI, CD-ROM, Combo Drive, 3GB SCSI HDD, ATI Mach64 PCI, SoundBlaster 16 Value, added a NIC to it) that I'm tempted to put on E-bay because I really have no need for it and am not that nostalgic about Pentium era hardware (the 486 era is my favorite), but on the other hand, I like the case, but i'm not sure I really want to "destroy history" by reusing the case with a 486 inside of it.
Got one guy lined up with a flip-top XT case and modded ATX PSU in XT chassis lined up for that box possibly, but I'm also considering a trip to RE-PC in Tukwila (their big store) so I can see if they have any actual Baby AT, AT, or XT style chassis there that I can get for less than $80-90 which is what they seem to be running now. The price of cases is insane now, I'm almost to the point of thinking about fabricating my own chassis at this point. At the very least find another XT PSU at around 130+ Watts I could slap in the case I had the 486 in before.
Been looking at letting go of some other systems soon eventally too, like the Compaq Portable 486c I can't find a replacement screen for (would be good parts for someone else as it works otherwise), my Mac SE that vegges out in my closet all the time these days, and then a pile of other parts that probably could be best suited to someone else.
