Hi Tom,

I finally picked these up from Mike and haven't even had a chance to go 
through everything yet (due to w*rk).

I have the backplanes available, please feel free to contact me 
privately if you want to.

As Greg said, the s100computer google group and are 
both great places to check out.

Boards that I and others have available are at (go down to 
the S-100 section if that's your interest and contact details for people 
are at the bottom of the page).

Specifically, Gary Kaufman's Altair 8800 CPU board reproduction might be 
interesting to you if you're looking to build as close a replica as 
possible (with nice light switching power suppplies instead of the old 
heavy, back breaking linear supply).

Also Josh Bensadon's JAIR board might be of interest as well.

I think Mike's cabinet, front panel and other boards if you want to stay 
mostly true to the original is a great way to go.

It's not a kit in that you have to source the boards and parts yourself 
(aside from Mike's prebuilt boards) but that's part of the fun (for me 
in any case).

Best of luck!
