I have one
I happen to have an ECS D6VAA Dual socket 370 motherboard.
Here's my unfortunate story:
I bought 2 x P3 1GHz (133FSB model) for $250.00
I received 1 dead cpu that would post, but would freeze on booting ANY OPERATING SYSTEM. The other CPU boots properly but has random reboots (if I type and press ENTER really fast in MSWord, the system BSOD's.)
The CPUs do this on 3 other motherboards I tried.
The vendor refused to take them back because they only allow for a 15day grace period, where I took 45 days to check the cpus on multiple motherboards.
So..... I still have a D6VAA motherboard. If you want it, e-mail me an offer (It obviously got very little use, I think I still have the box, I have the manual & cables, & it has the latest BIOS update.) For your reference, I paid $45.00 (not including shipping.) for it about 1.5 years ago. My trials and tribulations are posted all across
http://www.2cpu.com forums. If you aren't interested, check out ebay, there's a LOT of dual systems on there going for cheap.
--hope it helps.
