Jon Z. uses his cab-1L and he's forgotten more about technology than 99.999% of the people in the hobby.
Forgotten it? I invented a lot of it, patented it, and many products are still being sold and used after 20 years! I just like my Cab1. The batteries last for years, it is always on with a key press, quills the horn, runs the trains. Good enough to relax and get my “fix”.
