Hello, You can create BOM by look at www.s100computers.com, click board for sale then click on S-100 Z80 Master CPU Board then scroll down all the way until you see "Most Current Z80 CPU Board Schematic" then you can look the components and make a listing for purchase. Secondly, click "Most Current Z80 CPU Board Layout" then scroll down until you see board surface showed component marks with component types (blue). This will sure way for you to build your own BOM (Bill of Materials) then search components from eBay, Newark, Mouser, Unicorn Electronics and other vendors. I know it is not easy but you can help other members by post BOM to N8VEM/S100Computers websites and show where you obtain the components and name of vendors, part numbers, prices and for eBay, put item number, seller nickname and prices.
Hopefully, this will help you to start.... Good luck with your project...
