Hi Andrew and all,
I'm the biggest electronic novice attempting this project and I'm willing to risk it. For me, it's another learning opportunity. If it works: Awesome. If it fails, maybe someone will eventually find a workaround. Look no further than the late 1970's boards with spaghetti engineering changes on both sides of the board.
Yes, this can get a little expensive, but compared to airplanes or boats or even many cars -- this is cheap. I could tell you many horror stories about airplanes. Even when you think there is a sure thing, it turns out not to be -- then it can cost thousands or even lives.
This is a wonderful project. I hope it works -- but mostly I just thank you guys for all your hard work.
If it doesn't work, it'll be a very cool paperweight!
Thank you,
Robert Greenstreet
