I like 75LS stuff - have a stash at home for projects. :)I also have some CMOS stuff too but I've never had any occasion to use it since I prefer to deal with the voltage issue by using optoisolators or other level conversion circuits. Now that you mention it though, a streetcar with spontaneous state changing electronics could be an interesting ride! Electronics is the work of the devil if you listen to the local railfans though, so it's always fun to see some real discussion about electronics for transit or modeling purposes as opposed to the usual "When SEPTA K/PCC-II/TTC CLRV cars go to trolley museums, they'll have to rip all the modern junk off and install PCC equipment to make the cars run..." garbage. -Robert King |
