Hi!? I've been working on a home brew S-100 backplane as a side project for a while now.? I posted an initial draft version a few weeks ago and have made some improvements based on the comments. Here is some updated information on the schematic and PCB layout.? Comments, questions, suggestions are all welcome.? My plan is to make a small initial run of manufactured PCBs and would like to know if anyone would be interested. What I am looking for is a small group of experienced S-100 builders who'd like to purchase one of these boards (at cost, PCB only, plus shipping) to help with building it and checking it out. I am trying to keep the costs low but the PCB will be in the $30-$40 range depending on quantity.? Builders would need to supply parts, power supply, tools, etc.? The intent is to shake out the design with some early builds and get some feedback for improvements as needed. http://n8vem-sbc.pbwiki.com/browse/#view=ViewFolder&param=ECB%20to%20S-… 0Bus%20Bridge I designed the S-100 backplane for a small 7" x 7" backplane of 6 slots with an integrated active terminator. ?The active terminator circuit is based on one I bought in a home brew S-100 system and it resembles other active terminators of the S-100 era. If you are interested please contact me. Thanks and have a nice day! Andrew Lynch
