Dave, I still have some kits, drop me an email.
I haven't made progress on the TMCC booster, real life has gotten in the way. I'd like to get the schematic from Dale's family, it would really speed the process. I wasn't counting on having to reverse engineer the hand built prototype, really adds to the workload. I may have to punt on that project and hand it off to someone else. I'd be glad to do the PCB, but having to reverse engineer, build a prototype to see if I got it right, then do the production layout and schematic, etc. it more time consuming that I had counted on.
