This subject isn't limited to em machines, but I only have em's and I'm mainly interested to know what the em community here does. My question is: who keeps a log book for each machine? Recording: repairs, quirks, restorations, suggested fixes for things that tend to go wrong with that machine. If you do, do you keep it with (i.e. inside) the machine, so that if the game is passed on at any point when you're not around (well, it could happen) this very useful info gets passed on to the next owner? I keep imagining how great (sorry, awesome) it would be if my own pins had come with such log books. Anyhow, I've started one for each of my three machines, to be kept in the coin trays. Maybe I'll add a packet of toffees, with a strict rule that I can only have one if I've kept the log up to date.
