Pulled two ASUS VL/I-486SV2G boards out of my dad's archive this weekend. Both had Am5x86-P75 133MHz installed. Reddit correctly pointed out the missing VRM section so swapped in a 486DX2-66 before anything got cooked.
Rev 1.8 posted first try. 32MB FPM, Trident VLB for video.
Rev 1.7 has a crunchy socket. Not today.
Going on eBay shortly. Am5x86 CPUs listing separately.
Still digging.
