If you want a mATX board with AGP and ISA that supports a tualatin your best option is a Chaintech 6via5t, I've used one for some time and is a nice board.

6VIA5T is a great board indeed, I have couple that I have got good use out of ~

I already googled for that board. Looks like it is not available at the moment, is it? I can't find it in eBay or elsewhere.

I only saw a Chaintech 6LIA0. But this one has an Intel Chipset. If I understand correctly, this Chipset limits the amount of installable RAM to 256mb?

Edit: I was wondering if a socket A Mainboard could be a better choice. But when doing some research, it seems also to be hard thing to find a good combination of chipset, Isa and agp slot. mATX doesn't exist in that combination.

I just changed the title because I thought about keeping an open mind for what I want to build.
I think matx wouldn't be the best. But maybe I am wrong - I will go on looking for a good one.
I read a bit about 370 and 462 and am not sure what would be the better one. But will go on reading. So if someone has experience with both platforms and can tell about...
I only know the important things for me are the board must have agp and Isa. CPU speed should be around 1-1,5ghz.

Qdi advance 10t it is the way

If you want to go Socket 462 Gigabyte GA-7VX is a mATX board with ISA.

If you're also looking at socket 462, there are a couple KT133A based models that come with (usually a single) ISA port and even support the Athlon XP family, including the Thoroughbred-B. Personally I don't think the regular Athlon or Palomino-based Athlon XP are worth using over the Tualatin, due to high power consumption. But a 1700+ T-bred B would be my ideal pick:
- it offers the best performance, better than both Tualatin-based Pentium 3 or Thunderbird-based Athlon
- isn't missing any instruction set support, since it supports MMX, 3DNow! and SSE
- power consumption is not as out of control as on Thunderbird or Palomino based Athlons. Still higher than Tualatin, but it also offers correspondingly higher performance
- the CPU itself is dirt cheap to find, unlike the higher clocked Tualatins. Motherboards that support one or the other should cost about the same though

A couple KT133A motherboards that support it (sometimes not all revisions) include Abit KT7A, Soltek SL-75 KAV and DFI AK75-EC. All are regular ATX size though; not sure if there are any models that are mATX and have both an ISA slot and support the Athlon XP CPUs.

power consumption is not as out of control as on Thunderbird or Palomino based Athlons. Still higher than Tualatin, but it also offers correspondingly higher performance

XP 1700+ Thoroughbred-B can work at 1.2-1.4v (depends on silicon lottery) at stock clock which dramatically reduces power consumption and heat.

My experience is that reducing a 130nm Athlon XP's clock and voltage to Tualatin levels its power consumption gets similar too. I've tried it with a Barton but I can't see why a T'bred would be vastly different.

(Also I accidentally experienced that even a [maybe good] Palomino can run around 1.2V at sufficiently low clock rates.)

Interesting, I hadn't realised XP chips could undervolt so well. That certainly makes them even more attractive.

Does anyone know if Bartons can run on KT133A motherboards that support T-breds? I realise they're not officially supported, since they normally run at 333/400 MHz FSB while motherboards only officially support 266 MHz, but could they still work at the lower FSB speeds? I figure they probably should, since as far as I can tell the only real difference between the two is more L2 cache and higher FSB speeds. Barton 2500+ even has the same 11x multiplier as 1700+ T-bred, so at 133 FSB they'd both run at the same 1466 MHz core speed.

There is no reason why they wouldn't work at 266MHz FSB, although there is probably no microcode to identify the CPU correctly.

It POSTs as "unknown CPU" but works fine otherwise. I can't tell if there's any problem with SSE, though. But it should be initialized by the OS anyway so BIOS support is not that important.

So ... I found a board with Apollo pro 133A chipset. I could also get a 1ghz coppermine CPU for that one. If I get it right, this CPU is compatible with this Board. At the moment it is hard to decide if it's worth it. But it would have agpx4, isa and it would be mATX. Also it supports (not sure) 1 or 2 gigs of RAM.
Can someone give me hint if I should go with this or be patient and waiting for a better one.
Almost forgot... It is the msi ms-6154 (I know it is an oem board)

I did another research yesterday and found this: http://www.cpu-upgrade.com/mb-MSI/MS-6154VA.html. Don't know if the information given there is reliable. But if so, the Coppermine CPU SL5QV with 1Ghz is supported. In the MS-6154 Manual only speeds up to 800 MHz are listed. Does someone know wether 1ghz is supported or not?

If it supports coppermine 133mhz voltage and fsb-wise then it theoretically supports them all as they are multiplier locked.

looks like it does

Yeah just install a 1GHz CPU in there and it would work.

The manual page that you posted reads: Chipset VIA VT82C693A
This is not the Apollo Pro 133A chipset but the Apollo Pro 133 (without A).

https://en.wikipedia.org/wiki/List_of_VIA_chipsets

The Apollo Pro 133 (without A) has several setbacks: 10% a 20% slower than Apollo Pro 133A and does not recognize 512Mb RAM sticks
If you want the fastest Apollo Pro 133A you need the northbridge chip with a number that ends with 694.

Thx for information. I hope it won't be that disappointing. I will wait for delivery and when everything is assembled I will tell what I think about it. But will also have open eyes for a better one
