And here we are again with more tests on my SER-386-SS (RC2016) 386SX Motherboard!

This time I test way more CPUs and I push them to the limit:
1) New Am386SX Chip
2) An Intel 80386SX-40
3) A TX486SLC-33
4) A 486SXLC2-G50-WN

So... I compare 386SX vs 486SLC vs 486SXLC2.
New Overclocking records were reached!
A new, custom / modified ALI Bios is used!

Also for the first time I include FastDoom runs!
Yeah, Doom is actually playable on 386SX!
