WOzFest PR#6 Announcements

The sixth WOzFest, the informal, irregular, afternoon gathering of Apple II enthusiasts in Wollstonecraft, Australia happened on Saturday 29th April. Here is a brief recap of the announcements that were made. For full coverage, head over to the organiser’s blog post about WOzFest PR#6.

Manila Gear has announced that their version of the No Slot Clock is now available for pre-ordering. This device was announced at WOzFest 5.25 in November and has been delayed by software testing. It will be available for purchase at https://manilagear.com/product/no-slot-clock/

John Brooks told the gathering that he is working on a new version of ProDOS 8 that will incorporate drivers for the No Slot Clock and the DClock. This is not yet available but is already in testing.

Sean McNamara has produced an Electrolytic Capacitor ‘Spec & Check’ Sheet for the Astec Power Supply AA11040B/C which is a very useful resource for refurbishing Apple ][ and Apple ][ europlus power supply units. See his blog post for further information and for a link to the resource.

AFPBridge facilitates TCP/IP based AppleShare connections for Apple IIgs

Stephen Heumann has released AFPBridge, a tool that allows an Apple IIgs to connect to file servers using the Apple Filing Protocol (AFP) over TCP/IP. It works by using the existing AppleShare FST, but redirecting its network traffic over TCP/IP rather than AppleTalk.

With AFPBridge, anyone with a Marinetti-compatible network interface (such as an Ethernet card) can connect to AFP file servers from a IIgs, with no need to set up a LocalTalk network. This provides a very convenient way to move files to and from the IIgs, just by copying them in the Finder or accessing them in any other IIgs program.

See the AFPBridge website for more information.

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.
