As the banner says, I'm not doing anything new here - just documenting the steps that I go through to produce my own copy of the RetroBrew Z80V2 computer and ECB bus with a backplane designed for the Siemens 505-6508 enclosure. If you have previously completed one of these systems, I'd love to recieve your input. If you are interested in building your own, hopefully my experience as communicated here will be of help. I will be ordering my PCBs in batches of 10, so at a minimum there will be 9 "extra" of each that I'll be listing on Tindie as the project moves forward.
Wish me luck!
