All right.... This is my new build.
I had an 5x86-133 setup wich was beginning to run really unstable, so I got an Lucky Star ls486e C2 instead.

I have just finished this new build a couple of minutes ago, and I think this is running a bit better.
I wanted to aim for eighter an Dx2-66 or Dx2-80 on this build, though I can not get it to run with 3v CPU's.
The previous owner have promised that it will work with 3v CPU's, and I guess I will eventually figure it out.
I think that I am the one to blame, and that there is nothing wrong with the motherboard at all.

Anyway....
The build is made from the following parts.

- Lucky Star ls486e Rev. C
- Intel 486dx2-66 (Write through)
- Brand new "New Old Stock" 486-CPU cooler.
- 16mb 72-Pin 60ns Parity Memory (x36)
- Old AT case, with 3-digit LED, and Turbo button.
- 3.2gb IDE drive.
- Cirrus Logic CL-5446 2mb PCI video card.
- Media Vision Jazz16 based soundcard.
- Floppy and DVD drive.

I have finished this build today, and done some modding of some of the parts.
It is running nice and dandy, giving "144" in norton sysinfo. (basic fast benchmark in order to test turbo button)

First up. I have used a good ATX power supply from A-Open. With this I have used a simple ATX to AT converter.
I have modded the power-button cables with somme bigger plugs, because the case button's terminals were too big.
So I had to do some soldering today.... Fun. 😜

I have attached all images as inline, so a bigger one can be chosen by clicking on them.

Then I turned my attention towards giving power to the fronpanel led. I modded the led, in order to show 66 and
then I used this cable to give 5 volt to the led. Originally, the power came from the PSU it self.

All set correct up, and connected with the cable.

When mounting the motherboard, I had to use two of the red paper washers. One under and one on top of the board.

Then I tested if it would boot, mounted on the plate, before reattaching it to the case.

Success..... Mounted, and began with the rest of the build.

Last flood of pictures..... 🤣

I had to mount the ATX to AT converter, in order to not having stuff blocking the CPU fan.
And being fresh out of zip-ties, I used a piece of wire. Not beautifull, only effective. 😁

The build is done. I installed missing drivers and did some basic testing.
Doom runs fluid, Jazz rabit runs smooth and Duke2 are running great.

I have a slight feeling, that this is one heck of a machine. I allready love this baby. 😜

Your system looks very nice and simple. How is it working for you? Any particulars about your CL graphics card? I never got to try out one of those early CL PCI cards, don't even know if I have any.

Your case, does it still have its u-cap panel-thingy whatever are they called?

Yeah... It's simple and good. Feels solid and snappy for a dx2-66. 😜

The CL5446 is a fast card, up there alongside S3 cards.
Even Phil was impressed by it's performance. I was told that in a message he sent me.
The U-something... What is that exactly?
My case has all original parts, except for the PSU that were in it.
The new ATX is more silent and delivers 5 watt more on the 5volt rail. 😜

EDIT:
The CL card is first of all fast. Has moother contrast and warmer colours and not as
extremely bright as a Number9 S3-325 card, or an S3-trio64V+.
It might not be as compatible though. Yet this is only aprox' 3% of all games.
(perhaps even lesser)

If you want a really good card for MS-Dos 6.22, then go for a CL-5446 2mb PCI.
They are slightly cheaper than S3 Trio64v+ and has a better looking image quality.

Love it! Would love to see Phil's VGA Benchmarks and my Cachebench results for this system. Especially to compare the PCI to my VLB system (GD5428).

Thanks for sharing the pics and stories.

Keep an eye out for benchmarks in this tread.
I have build it. Playtime comes later, as I have some other hardware to test before benching.

It's not called a side panel, cause it covers both sides and is shaped like the capital letter "U", but upside down (the metal thing that you put on the case to close it up).

Sorry, non-native English speaker here 😵

And nice to see some CL love here, if only for a change to something different 😀.

Ahhh.... The case cover? Shure I have that too. It's all original. I got the case from my parents originally.
It contained their second pc. (P133, 64mb, Ati Rage Pro, SB16)
Well... Don't be sorry. English is my second language, so I know how it is, not really knowing a specific English word. 😉

Anyway... Some more Pic's, since you asked about the cover.

Aww man, I need a 3 digit display and your not even using it!, only PC I have under 100Mhz is my DX2 66, but that's my very 1st Pc in all original condition soo that's not changing.
But its defiantly period correct case. Same as our school had their 486/33's but have seen the case with systems upto early Pentiums.

DX2 66 is a nice system to play with. it was what games had as the minimum requirements for years and its interesting to see what passed as playable

The case originally came with an P-133 setup. Back in 1995, I had a Dx2-66 with a case matching this look. (if not the exact same case model)

The 486 machine that I had in the case I have used, was a 5x86-133 on a FIC 486 VIP IO.
Though the motherboard is a bit unstable, and I need to test it out with 5volt CPU's.
