In order for a PC motherboard to be a replacement candidate, it has to have the Cyrix MediaGX 200, 233 or 266 mHz processor. And it must also have the 5520 companion chip, and one of the following types of super I/O chips: SMCFDC37C932, SMCFDC37C931, NSPC9731. Note Williams used several different style of PC motherboards in their Pinball 2000 games. These vary in color and layout. But they all have the above chips in common. The Cyrix Media GX board system was choosen by Williams because it was an "all in one" CPU board, and it was inexpensive. Unfortunately Cyrix went out of business, and it's assets were purchased by National Semiconductor. Via then turned around and bought all the Cyrix assets from National, except for the Media GX line (Via had no interest in this system). Since National did not have the right to use the "Media GX" name, they renamed the line "Geode". National still makes the Geode line of chips and boards, which are using the 5530A chipset (an update to the 5520; Williams was porting Pinball 2000 to the newer 5530 chipset when they closed the pinball division). But unfortunately the new National Geode boardsets usually lack PCI slots (and some other required features), and the newer 5530A chipset is not Pinball 2000 compatible. So the new National Geode boards are not usable for Pinball 2000
