Socket Super 7 (perhaps Ga-5AX, P5A or something like that)
K6-III + 450/550mhz
Voodoo3-3500
Some kind of Yamaha soundcard (724?)

EDIT:
Most likely an Audician32 😁 It might be an replica or near exact copy of the one in Phil's recent SS7 series.

Let's try..

MS5169 Ali based mainboard,
K6-3 450 @ default
Voodoo3 3000

😁

Ooh, this has got me excited 😀

98se, k6 iii 450, voodoo5 5500, yamaha xg sound card, one stick of pc150 memory.

M919 or similar 486VIP, AM5x86-160, Diamond Stealth3D 2000, Diamond Monster 3D II, Sound Blaster AWE32

Colonies of mice & spiders?

Ok im not spilling the beans yet but 386sx mentioned the MS5169 which I have. Mine is a revision 2.1 that supposedly doesn't support K6-2/3+ CPU's. The revisions 3.0 and 4.0 do with BIOS 3.5 which again supposedly you cannot flash to a revision 2.1 board. So I fire it up, boot from floppy, startup the flash program, hot swap BIOS chips and flash BIOS 3.5 to my revision 2.1 board. It boots and it properly detects the CPU. Hmmm I wonder if bad things might happen? The revision 2.1 board is interesting in that it has the holes for a SB-Link but no pins. That might be interesting for a YMF724 card. What do you think? If anyone can think of something that this might cause an issue with let me know and maybe we can test it.

Sadly looking at the YMF724 datasheet the SBPro block has registers for the filters but they do not operate. I think I interpreted the data correctly. Oh well I'm off topic.... what else is new?

I can confirm with 100% certainty that it will contain an AMD K6-III+ 450ACZ CPU. It's a 2.0 Volt Core CPU.
