Here's something that serves almost no practical purpose and effects only a tiny fraction of enthusiasts, but yet is still interesting to see nonetheless. The crew at OCWorkbench got SLI working using a combination of modified drivers and PCI Express and AGP GeForce 6600 cards with a motherboard based on a ULi chipset.
"As we all know SLI is always said to meant for the PCI Express interface. In this experiment, we will find out if AGP can support SLI. In this test, we will use the famous ASROCK 939DUAL-SATA2 based on ULi chipset. It is the ideal test platform as it supports both native AGP and PCIe slots."
Next up, SLI with PCI-based GeForce 6200s. (Just kidding. I made that last part up!)

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
