From the europlus blog:

I’m very happy to announce that the next WOzFest, WOzFest Slot 7: Your Card, will be held on Saturday 22 July 2017, starting around midday Sydney time (UTC+10:00).

The theme for the day will be “The IIgs”, and was requested/selected by attendees at WOzFest PR#6.

In addition, the now-annual video hookup with Kansas Fest attendees will start at about 14:00 local time (23:00 Friday Kansas City time).

Further details on the announcement post, and updates will be posted under the europlus blog’s WOzFest tag.
