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
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.
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!
