Got this Intel SE440BX-2 board today.
I have a thing for Intel boards, and this one is a fairly complete version: an onboard Yamaha XG chip and support for Coppermine chips. Technically, I could put one of mine SL4KL 1GHz Pentium IIIs into this thing and get a very fast system, but I feel like a more classic Windows 98 build would be more suitable. Something like a Pentium 3@500, a Matrox G250, Voodoo 2 SLI with a SoundBlaster 16.
The onboard Yamaha chip should have SB-Link enabled (called PC-PCI link in the manual), and I'd like to mess around with PowerYMF drivers and soundbanks.
I also got a Yamaha DB50XG daughterboard (pictured here together with my SW60XG card) — it will be paired with my SB16 CT2230. Playing some games with it right now and loving it.
