My last project, the Compaq deskpro 4000 5133 is back in its box.
Some hardware trouble that I dont feel like dealing with right now, instead I found the acual motherboard I used for a little less than a year 1997 - 1998.
Im the type of guy that saves almost everything so most motherboards I have owned but not managed to sell I still have lying around in closets and drawers.
In the autumn of 1997 I bought a cheap Soyo SY-5EAS and a then very expensive pentium 200 mmx.
The soyo board uses the Via Apollo VPX, a chipset that has a somewhat dubious record but I cant remeber that I had any serious issues with it.
The pentium mmx I had was a really good overclocker, it did 250 and 263 mhz without breaking a sweat and 291.5 with the case open and 0.2v extra voltage.
Sadly I sold it to a friend that used it to upgrade the p133 machine he was running, luckily I have gathered lots of PC junk since then so finding a new one was not an issue.
I found 4 pentium mmx when I was looking for parts in my apprtment for the deskpro build, three 200 mhz and a 166 mhz.
Two of the 200s turned out to be lacking the 3.5x multiplier, and the third hanged while booting dos at 3.5*75mhz. I only used a small heatsink without any grease during initial testing so perhaps it would be able to run at 263 with proper cooling.
The 166 mhz turned out to be the strongest, it has no problems at all running at 263 mhz at stock voltage with only a small heatsink. Now when it has a fan im sure it will do 291.5 mhz if I add a small amount of voltage.
Since this is a proper build in a big case I can use the full lenght awe32 that I also found while looking for parts for the deskpro build.
First I thought of letting a voodoo 3 2000 to handle the grapics but the cpu will not be able to utilize it fully so I will save it for another build.
Instead of the voodoo 3 I chose a Matrox Millenium II and the voodoo 2 I used in the earlier build. A 3com network card and a 64 mb PC 100 sdram stick and the hardware list is almost complete.
The case I plan to use comes from a dual pentium pro server which I rescued from the same dumpster I found the Compaq deskpro in, this must have been during 2002 or 2003 since I moved late 2003.
The case can hold two complete systems if you use baby AT motherboards, or just one system if you use a full size AT board as was the case when I found it.
It also had dual redundant power supplies which I sadly cant find so they have probably been lost while moving or perhaps they are in my cold storage under loads and loads of tires belonging to cars I used to own.
Enough of talk, where are the pictures?
Oh here
The Leviathan
Not that big you say 😁
Its easier to get a grasp of the size in this picure where you see the two holes that will fit motherboard trays
And the hardware that soon will fill it *cough cough* ... fill some of it.
Say what you want concerning the Soundblaster awe32 ct2760 but its pretty intimidating, fits this build perfect.
A cpu that diddnt meet the criterias for this build, I kind of like overclocking.
Another bad apple, there is a third but it looks exactly the same. The forth and best is mounted on the board.
The Motherboard or to quote a swedish magazine* "The Mother Modem -The heart of the hardrive" *not a computer magazine
The Matrox Millenium II, scratches everywhere. This card has been with me since it was bought new, think it was in 1997.
The Voodoo 2 card, the same as I used in the deskpro.
An old 3com ISA network card
A quick check with speedsys to see that things are working... Almost 200 cpu points, not bad.
I also did some game testing. Pinball Illusions works great, Tyrian gets the "over 300 mhz pascal compiler bug error" altough the cpu only runs at 263 mhz. I cant really take this as a bad sign.
