I started a thread about another odd type of motherboards, Socket 423 and 478 motherboards with the universal AGP slot which are not as common as their 1.5v keyed only AGP counterparts, but still useful for some things, including Voodoo cards, and maybe make fun with them, especially when testing and comparing.

Here a list of motherboards i could find arranged by chipset, the list is incomplete as now (i'm still looking for more motherboard on the net), some Socket 478 boards might support Hyperthreading (Pentium 4 3.06 GHz Northwood HT FSB 533, ethier on the model istelf or a revision of the model, please check CPU support). This tread will be updated eventually. Boards with link have The Retro Web page
