@brostenen; Yeah, the P133 is a decent platform anyway. They were stable, easy to modify/upgrade and ran pretty much everything a 486 did but better.
But most of all I agree with
Same reason as everyone else here. I like old hardware.
It could be worse, he could be running an IDT WinChip or something. I do, it's rubbish, but do I enjoy owning it and using it? Yeah. Was it prohibitively expensive? No. Sure, I know I could stick a K6 in that board (I moved it to a PC Partner one) and leave it for dead, I know I could have never set it up in the first place and it drags it hangs its bag out when anything uses the FPU. Whatever, it makes me happy, it's good enough. As for the Pentium, like I said, decent platform. Besides, it would probably be enough to play a fair amount of older user content in games like Doom and Duke where the mapper cranked the detail up. You wouldn't want to play Billy Boy's maps on a DX2-66, that's for certain. Even Fernando's New York Rebellion would probably be stretching it and if you run a much newer system you may as well just run a port which would play on modern systems anyway.
On that note, I do go around saying things are rubbish a lot. But I will NEVER say that somebody should not like the object in question.
