awesome! I like the idea of a baby-AT slot1 build... and the pic descriptions are priceless 😁 🤣

Very nice and neat build! I don't like the fact that the slotket with the CPU is hanging there for the long term!

My retro PC consists also from a babyAT slot1 mobo and a PIII 750. It works with any Coppermine CPU with multi up to 8x, just like my microATX 440BX mobo. If I install any CPU with multi 8.5x and up, it refuses to boot. I think the PIII-800 is the best cpu that one can have in an AT case & mobo. (I have seen a s478 AT mobo, but I guess is extremely difficult to obtain!)
Too bad that yours doesn't accept newer CPUs.

I think it would accept newer CPUs since the Katmai 450 works, just not the Katmai 600 for some strange reason.
I think it needs to much current at its default voltage of 2.05v, I bet that it would post if I did a tape mod for 2.2 or 2.3v
But things are a little murky.

The sticker on the board indicates that the board is a PC-Chips M747
The thing is that those boards dosnt even have an AGP-slot and uses another chipset so it clearly isnt.
I remember that the manual I got with the board was for a board with integrated video. I had to read the jumper setting on the board since those listed in the manual was wrong. 😁
The board is identical to PC-Chips M726 and I think it is PC-Chips verson of it, not one of the rebranded boards like Amtron.
The really strange thing is that the M726 revisions are called 1.2A, 1.2B and 1.2C or something like that. My board is revison 3.4.
The BIOS flash tool that comes with the BIOS diddnt work so I had to use uniflash to update the bios.
I read a post on another forum witten by another person with a M726 also with the nonexistent revison 3.4, he also had to use uniflash.

Best of all, with the new bios all cpus get identified as 66mhz fsb cpus like p3-300 450mhz

This one is also pretty nice although I dont think any board can correctly identify an unlocked p2. It works at 2x multi aswell and gets identified as a p2-133 😀

I have a board very similar to yours, uses the same chipset but the ATX power connector is on the right side of the CPU slot. Will see, if I can get it out of the case tomorrow and take a photo.

I dont think this computer will get used much.
It works well but the Abit BH6 build is faster and have USB 😀
I really need to find the ATX form factor card for this board.
But its good to have a few computers in reserve.

Here are some more benchmark pics, this time with the P3 450.

interesting!

does this board work with a coppermine cpu?

Celeron 500 FSB66 Multi 7.5 2,0 Volt 27,0 Watt (Mendocino)
Celeron 533 FSB66 Multi 8.0 1,5 Volt 11,2 Watt (Coppermine)

Doc

I have not tried any Coppermine CPUs with this motherboard yet.
I do not think the Mendocino Celerons power usage is a big deal but I will update this thread if I switch the CPU for a Coppermine in the future.

Ive got the same bxcell board in mine :3 not a bad board at all.

PS if you do some digging you can find the pinouts for the atx breakout board and add PS2 and usb 1.1 output 😀

I will probably do that some time in the future.

The chipsets real name is ALi M1621, also called "Alladin Pro II"
PC Chips likes to confuse us with made up chipset names 😀

This is what I call Ugly Duckling builds. None of the parts are desired or popular but still make a decent PC in the end. You even have rust, doo-doo and a pube to um enhance? that affect.
Good to see the parts able to live again!

I certainly hope that's not a pube from his youth, seeing as how it looks to be either silver or gray. More likely a carpet fiber??
