Billa: the MB is an FIC VA-503+. It supports both SIMMS and DIMMS, 1 agp, 3 PCI, 3 ISA. I can not vouch for the stability of the board but considering that it is the only MB that I have that supports Super Socket 7 chips, I might as well just had you the 550 and the MB for the same price as the 550
How much you want for it?
BTW this system is comming from a kids machine that hopefully I will be replacing with a Ghz celeron system shortly. That is the reason for the 2 week delay.
