Oz KFest 2017 – August 30th – September 3rd

The next Australian multi-day retro computing gathering, Oz KFest, will be happening on Bribie Island near Brisbane, Australia, August 30 through September 3, 2017. Come join us down under for a few of days of retro inspiration, Aussie ingenuity and camaraderie!

The goal of the event is to provide a user group style environment to exchange ideas and discuss new developments in retro computing hardware, software, preservation, emulation and other related topics.

There will be a few attendees of past KansasFests and Oz KFests in 2009, 2013, and 2015 and we hope to imbibe the spirit of these events into Oz KFest once again.

Having grown in numbers of attendees over the previous 3 events, this year’s event will take place at a venue that provides onsite accommodation and catering which will further facilitate interaction between participants and provide an experience very similar to the well known and loved KansasFest.

The presentations during the weekend will come from the participants and therefore an invitation is extended for session proposals to be made via email to ozkfest@gmail.com

If you have an idea for a session that you’d like to present, please let us know so we can allocate a time slot for you. If you would like to learn something, let us know what that is and we will try to find a presenter for that topic.

Registration for the event is not yet open. However, now is the time to block out the dates in your calendar, arrange how to get there and plan your session topics. If you need help, let us know how we can help.

For event details, see http://ozkfest.net and for breaking updates follow @OzKFest on Twitter.

Reminder that the ‘Downunder Chat’ happens every Friday night from 9pm Australian EST in irc.a2central.com #a2.chat

DynaComp 240V power supply dissection

Long time Australian Apple // enthusiasts and full time technicians Dean Claxton and Mark Cummings, lamenting the lack of official documentation on power supply circuits, have reverse engineered a circuit diagram, schematic and a parts list for the DynaComp 240V power supply (model 699-00136) which was commonly used in the Platinum Apple //e. The DynaComp 110V power supplies are probably very similar and therefore these resources will be useful for troubleshooting those models too.

The article also discusses testing capacitors in-circuit using an ESR meter.
