Orao WiFi/RS232 and Orao Terminal emulator

Orao was a Yugoslav 8-bit computer developed by Miroslav Kocijan for PEL Varaždin in 1984. Orao was designed for use in schools. It was common in elementary schools, mostly in Croatia, through the late 80s. Since 2021, I’ve been learning more about this microcomputer and developing hardware and software for it. While most of the information here is available on my Orao github repo, this page contains all the relevant

Ode to Twitter

This is a translation of the article I wrote for Kulturpunkt.hr about the demise of Twitter, my personal history and feelings about what’s going on after Elon’s takeover, and my hopes for building better online communities in a post-Twitter world. It’s a direct translation from Croatian, so there are some references to “domestic” Twitter etc., which refer to Croatian and post-Yugoslav online communities. The article was published on November 15th

Remembering my grandfather for 100 days

Following Elon Musk’s takover of Twitter, I decided to finally leave that platform. I’ll be writing about my history and complicated feelings about Twitter in the future, but for now I’m archiving some important posts and threads that mean a lot to me and which I want to preserve. I’m starting with the 100 days posting photos and memories of my grandfather, after he passed away from COVID in October

Revolution During Disintegration: Lessons from a Short History of Yugoslav Computing (HOPE 2022)

This is a recording of the talk I gave at A New HOPE conference on 7/24/2022 in NYC. I have posted it here until the official recording is available at https://www.youtube.com/user/Channel2600. The socialist Yugoslav state was in many ways an aberration of the polarized Cold War period. Socialist, but not Soviet-aligned; friendly, but not exactly allied with Western Europe and the U.S.; its unusual position produced unique developments in computing.

Remembering Josip Gobac, my grandfather

Note: this is the English translation of the obituary I wrote for my grandfather in Croatian in October 2021. You can read the original here. On October 14th Josip Gobac, the Director of Television Zagreb from 1978 – 1986, passed away from COVID-19. He was not only a successful journalist, a talented painter, an unstoppable hiker and a big nature lover, Joža Gobac was also my grandfather. He died at

Building a Galaksija, Part III: Audio cassettes, magazine listings and radio waves

Note: this is the third and final part of three articles about my experience building a 1980s Yugoslav 8-bit computer called the Galaksija. This part is mostly focused on software creation, distribution and preservation. You can find Part I, focused on the tech, here, and Part II, focused on the history of the Galaksija, here. It is largely based on my sprawling Twitter thread about the Galaksija. The first computer I

Unlocking an SPA-2102 ATA in 2021

Note: this post was originally published as a Twitter thread. Recently I watched Cathode Ray Dude‘s videos on faxing from Windows and dialing up at home, and I was inspired to experiment with modems and faxing myself. He has a great article on configuring an ATA (analog telephone adapter) to place calls between phones/faxes/modems without a need for a telephone network. I went ahead and got myself an Linksys SPA-2102

Building a Galaksija, Part II: The Origin Story

Note: this is Part II of three articles about my experience building a 1980s Yugoslav 8-bit computer called Galaksija. This part is mostly focused on the history and the cultural impact of this machine. You can check out Part I for the story about the tech. Part III will focus on the software, community and Galaksija’s legacy. This article is largely based on my sprawling Twitter thread about Galaksija.  In

Building a Galaksija, Part I: The Tech

Note: this is the first part of three articles about my experience building a 1980s Yugoslav 8-bit computer called Galaksija. This part is mostly focused on the technical aspects of building this computer. Part II will focus on the history and the cultural impact of this machine. A BCS version of this article was published on RetroInfo. It is largely based on my sprawling Twitter thread about Galaksija. At the
