I just love post intel processor Dover/Thyssen units, T4 with scr drives by far my favorite, Dmc easy, kcm831, love them except in parking garage where moisture is an issue, otis (sorry green guys) are boring, old relay logic walk in park. Schindler least favorite... I have anything from circle bar w. To 32 bit Thyssen units., Circa 1900s to current, on my route. Fun fun....
