Hi there!

Some additional announcements ;-)

August 21-25
The Chaos Communication Camp will take place next week near Berlin, Germany.
I am organizing a Gigatron workshop there, introducing the concept and the device to newbies, with hands-on the latest ROMv4, monitor, simulator and development.

September 13-25
Balcoon 2019 is a big Hacking Conference near Belgrade, Serbia.
I have been accepted to speak about the Gigatron. Anyway I am not sure to attend the event yet. I hope to make it anyway and will update here if needed.

I don't have any goals apart sharing my love of the Gigatron to new people. I hope this makes sense! If you happen to be at any of these places, I would be more than happy to meet ;-)
Marcel already told me he and Walter won't be present at those two events, anyway that's cool to present the Gigatron to the masses as it's so cool.

Nice! I wanted to present at the 34C3 but the talk was rejected. Now you can redeem us! :-)

Rejected talk? Wow, that's sad. At least at CCCamp, it's a "self-organized talk" so I don't need to ask anyone for approval ;)

I still have some issues to solve for the workshop: I'll bring my own Gigatron to show on screen and to explain the electronics, but as I only have one (well, two but the other one is still in kit), I thought about preparing some Raspberry Pi 3B+ for the attendees to play with the git contents and the simulator.

But as I am testing today I realize that :
- Martin's visualizer (ScriptTest) binaries aren't working on ARM platform and there is no sourcecode (I believe this app comes from the demoscene... :D )
- The online emulator is too slow with Chromium so it won't be good for the workshop.
- I compiled at67's emulator (gtemuSDL) without any issue*, but it's also way too slow. Maybe I'm missing something here?

So, the Raspberry PI 3b+ is not fast enough... :|

I'll find an alternative way to do the workshop, probably by helping attendees to install all of this on their own laptops !


* Tip: if you need to build+run gtemuSDL on a fresh Rpi install, here are the commands:

Code: Select all

git clone https://github.com/kervinck/gigatron-rom
cd gigatron-rom/Contrib/at67
sudo apt-get -y install cmake libsdl2-dev
cmake .
make
./gtemuSDL&
As simple as that.
