Good to hear.
But as far as the breakdowns go most machines back in the day were played to death, then you had some techs that would just "patch" the problems due to not having the correct parts or not having the time due to the 10 or 20 other amusement centres they had to drop by on any one given day.

then remember a lot of machines were several years old and really needed  "full shop jobs" but again only the parts that failed or were visibly about to fail were replaced.

if you drive your car day in day out and only replace parts when they fail then you will have a lot of breakdowns after a certain amount of KLM's, but most of us don't do this, we service the car and replace parts that wear at set intervals so we have less break downs.

if you want less breakdowns then service the machine on a regular basis
