Usually I prefer to buy many motherboards, but sometimes I find some special boards, sold individually, and if the price is not excessive, the purchase!
Recently I ran various benchtop DOS with a couple of S.370 motherboards, one with SIS chipset and the other with i810, unfortunately both cannot be updated to Coppermine (only Mendocino), but looking for an S.370 for Coppermine, I found something better!
An ASUS TUSI-M, SIS chipset with Tualatin CPU support, honestly I already have a TUSL2-C with P3S-1400, which has less the amount of installable memory, only 512 MB against 🆚 1 GB 🇬🇧 of the TUSI-M, for the rest it should be better.
I don't know how long it will take to arrive, but as soon as I have it between my legs 🐾, I'll see to put it on and start doing some bench, the paper seems to be in excellent condition, and the paper manual and the original box are included.
