I have been looking at building pci (NOT PCI-E, old school pci) In a effort to balance cost with performance I have been looking hard at something like this IF i could figure a way to update it.....

Very compact design repeated over and over, I just dont get a few things like how the pci connection is interfacing with the FPGA's when there appears to be no PCI bridge (I guess that is what the ribbon cables are for?) I know a little about how electrical circuits theory works, but this is out of my comfort zone. Does anyone have any advice?

The most helpful to others would be high resolution images of both sides of the boards - the fast paced camera movement is not helpful at all. I tired some of the obvious searches:

https://www.google.com/search?q=site%3Adsptools.com
https://www.google.com/search?q="DSP+Tools"+filetype%3Apdf
https://web.archive.org/web/19961220051801/http://www.dsptools.com:80/

As important as the drivers (which might be something standard or compatible in the industry), would be the firmware. It looks like something used for automated testing of hardware. If I had to guess - from an examination of their other parts - I would say this was a custom job for a particular client. And not something sold from their website.

I was afraid of that, I reached out to the guy in the video and have yet to hear back from him. (Not my video....) I was hoping for a weekend layout and send it off to be manufactured after that a weekends worth of populating and soldering. I don't think drivers/firmware for that would be to awful to make once you got a bearing on it. (Sure wont be pretty but could work....) Note I am pretty sure this will very from brand to brand, and maybe even between series in a brand.

I question what firmware would need to be wrote for something like this, but I must question if the standard then would be the same as it is now with the massive increase in power those chips have.

Sadly this looks like it may be more trouble than it is worth, granted maybe I am being a little bit of a pessimist.

Edit take that back I think this is doable again! Now to go into PADS and lay this out! Bit coin mining FPGA cards were useful to look at, they gave better information then that video!
