Picking nits--the J700 also has the extended PCI slot and the PCI-PCI 
Bridge.   Of course, one could argue that the J700 is an S900.

The J700 was Umax's lower end professional machine.   It came in a 
desktop case (S900 is in a tower) and has only four PCI slots. 
However, the fifth and sixth PCI slots are provided for on the J700 
motherboard and one need only install the PCI slot connectors in 
order for the J700 to have six slots.

In other words, the J700 motherboard is the same as the S900 with 
fewer components soldered down.
