Re: 486 Motherboard

Looks like this SIS 49x chipset layout was popular :happyhappy: Hmmm. Well whenever I see similar designs across manufacturers, I think that they were all following reference designs from the chipset maker. BTW, I'm fairly sure that the reason my uber-homebrew PS/2 mouse port doesn't work is that …

Are those two fake cache chip spots at the top right corner of the board?? The pads and the traces from them look totally fake, with the traces going in circles. So the board comes with the option of a real cache in COAST module form, or some fake plastic things in the top corner. lol Does it work …

that reminded me that I actually tried to overclock the P133MMX TCP module. There are some spots that look like jumpers, so I got out the old soldering iron and went at it. Only managed to underclock it though, and I'm not sure that it was the multiplier that was changing. So I gave up. 😉

You have more RAM slots! I am inferior!! And you have a header for the 440fx USB (hmmm...) Yeah kick that into 233 MHz "high" gear and see how things go. The best way to test stability I found is to run Prime95 torture test and while it's going try loading other apps and see if they crash. Prime95 …

but it has!! that big AMIKEY 2+ chip on the bottom left is for PS2 mouse support! I got very ambitious last night and desoldered a PS2 port from the Socket 4 board that I'm never going to use (and probably doesn't work) and soldered it via some ribbon cable to the MSI board's blank PS2 mouse spot. …

Swaaye, I really like that heatsink on your MSI board. To me it appears that you used a large socket7 heatsink and used a special clip. Did you fashion the metal clip yourself? The heatsink must be from a Pentium, but the clip is from some other 486 cooler I had once. Works nicely, that's for sure. …

The performance boost I got when I upgraded the CPU was quite big....some SVGA games almost run too fast now...like Nascar and Formula One Grand Prix 2 Windows 98SE really flies...thinking about trying Win2000 and see how it performs Also fun to know you own a system no "mortal" could afford back …

I also own a Socket 8 mobo and a Pentium PRO 200 MHz 1 MB Cache CPU, but I never had time to build a working system. What fans will work with Socket 8, because my CPU arrived without any heatsink? I think only Socket 8 heatsinks fit it. Nothing else is shaped like Socket 8. As for the fan, I just …

but it has!! that big AMIKEY 2+ chip on the bottom left is for PS2 mouse support! Hmmm... Well the board obviously has an area for dual PS2 ports, but this one is wired up for that AT DIN. Not sure what to do about it.... Would be pretty sweet to take that off and put a pair of PS2 ports on. I have …

Pentium Pro systems

Posted on 2008-09-06, 21:55

So, who likes to mess around with PPro? These CPUs intrigued me from day one, because of that on-package cache and their impressive FPU performance that was untouchable by just about anything else (certainly nothing from AMD, Centaur or Cyrix.) I picked up a nice Intel mobo, the VS440FX "Venus". …

Re: 486 Motherboard

I've had a few 486 mobos. Back in the day, I went from a ISA only board that came with a OEM sys to a MTI R407e mobo with VLB+ISA. But I really prefer the boards with PCI because, if they work well, they support most (if not all) Socket 3 CPUs and also work with most PCI cards (meaning lots of …

Re: Pentium 133 MMX

133 MMX was in lots of notebooks. No...it wasn't. The mobile version of the MMX processor started at the Pentium 200. The desktop version of the MMX processor was the P55C, which started at the 166 MHz processor (officially) but then Intel decided to make a 150 MHz version of the P55C also. Nothing …
