I'd love to help George, but I'm useless at Zaccaria pins (long story) and you moved from "just around the corner". 

Competent Techs that know the make / model / genre can usually fix games onsite.  "Return to base" often can be translated to "we have no idea how to fix your pin and we don't want you to see that". But I honestly don't know ANY Zac techs other than a handful of guys here.
