Still don't have a working 486 system in my collection, and have noticed that 486 motherboards on eBay have become ridiculously high-priced; I'm guessing because of the retro gaming craze. Apparently there's a lot of retro gamers who insist on authentic period hardware.
Since early Pentium system boards haven't gotten that expensive, I was considering the possibility of getting one of those instead. Given that later model 486s ran at 66Mz, 80Mz, and faster I was wondering how did they perform compared to an early 60Mz or 90Mz Pentium? Does mainboard cache make much of a difference?
I already have a tweener that runs a 1Gz AMD Athlon XP cpu. Trying to run MIPS or SI on that gives some ... interesting results, shall we say. Even disabling the cache & kicking the bus speed down I only get it down to 700Mz equivalent, from the vintage utilities I've tried. They weren't made for modern processors. Not much of a gamer here, but a lot of older software (eg MS-DOS applications) don't like speeds that high
So would a low end Pentium system be an equivalent until I find an affordable 486, or is the generational jump too great? I was thinking of something 200Mz or less.
Oh, the irony. Back in the early 90s I couldn't wait to dump my 486dx2-66 for a Pentium system. Took me forever to afford one, and a "slow" Pentium MMX 233Mz wasn't fast enough. Now I want them back, and... Heh.
