Jim Tanner, of Tanner's Electronics in Carrollton, produced various S100 boards, as well as Ferguson's bigboard, and, I believe, helped work out the deal with Xerox for the 820 (which was a bigboard clone in a box). When the 820 flopped, he later bought hundreds of surplus 820 PC boards from Xerox, and sold them in his store. Perhaps he may know where you can find something.If they had a Xerox 820, I'd probably make the trip to buy it, but I'm more of a retro-designer than a vintage collector and restorer. I've got every system I bought back in the day, except my Xerox 820s. I don't need those but I've got all the documentation and software so getting one would fill a gap. I expect to be running all Xerox code and floppies from a retro design soon, anyway.
I quit MEETUP.COM. It wouldn't let me acknowledge that I'd attend meetings nor post a message saying that I was coming to the meeting despite the stupid website not working.
If the Dallas Retro Computer group can let non-MEETUP.COM people into the meeting, then I'll show up.
I suspect the previous group switched to facebook.com instead of meetup.com.
I think July 11th made more sense. Fourth of July was a bad pick.
I'm in Fort Worth, but I am very familiar with Electronic Discount Sales. I now own some of those items
I was actually there yesterday to film what they had left for my youtube channel.
