S100 Computers S-100 Extender Board
This is a post era board. That is it's a recent design and DIY construction. See many great post era boards as well as an excellent historical resource for classic S-100 buss computers at S100Computers.com Check out the S-100 Extender at the S100Computers.Com site. Links to schematics and construction notes are available there.
The boards are purchased in mass by members of the N8VEM community. I purchased the bare PCB from a member of the group, sourced the parts and assembled it myself. I built two of these.
