[vcf-midatlantic] Rarity of these boards

I don't know much about S-100 boards, so I'm asking the group. Someone was asking if the following pictures should be save: https://drive.google.com/drive/folders/1Jh43LAsiwnyor4rrGUYLZG4YlJt0K9H7?usp... I would say yes. They seem to be S100 boards by CompuPro. A Google search tells me this: http://www.s100computers.com/Hardware%20Folder/CompuPro/MPX%20Board/MPX.htm Can anyone add to the factual Google search information? ========================================= Jeff Brace Vice President & Board Member Vintage Computer Festival East Show-runner Vintage Computer Federation is a 501c3 charity http://www.vcfed.org/ jeffrey@vcfed.org
