My GlobalTalk Setup #1: Apple Internet Router configuration

It’s the middle of MARCHintosh! Thanks to the unexpected GlobalTalk craze, I spent the first two weeks of March having a great time participating in the world’s first global AppleTalk network. The first few days were wild — I’ve already documented my setup to interconnect a mini vMac emulator to my SE/30 running the Apple Internet Router to connect to the rest of GlobalTalk, but as of March 16 this

Using TashTalk with Mini vMac to participate in #GlobalTalk from your emulated Mac

It’s MARCHintosh! The month when the vintage computing community celebrates the classic Macintosh experience. This MARCHintosh started with a bang – seemingly overnight, the #GlobalTalk network took over Mastodon and soon many of us were networking each other’s disparate home AppleTalk networks into a #GlobalTalk network across continents. We’re still in the middle of the #GlobalTalk craze and I expect to write more about my experience further down the line,

There and back again: a Macintosh 512K saga

Note: this post is based on a Mastodon thread. Last summer I got a Macintosh 512K at the VCF Swap Meet in Wall, NJ. I’ve been wanting to get a Fat Mac for a while, ever since I read Andy Hertzfeld’s book Revolution in the Valley: The Insanely Great Story of How the Mac Was Made. Well, technically I wanted a Mac 128K, but I had no interest in paying

Yugoslav adventure games

Note: this article was originally written for the Club de Aventuras AD magazine. You can read it in Spanish translation starting at page 68 of Issue 60 of CAAD. Home computing in Yugoslavia, a country that no longer exists, was quite interesting in the 1980s. The geopolitically unique position of this socialist country during the Cold War produced a unique situation in terms of access to computers and technology. Yugoslavia

TRS-80 Model I restoration

Introduction In early June I went to the VCF Swap Meet in Wall, NJ and picked up a supposedly functional TRS-80 Model I. I haven’t been very interested in TRS machines (other than owning a CoCo 2 for a moment) until I watched a video by Dejan Ristanović, one of the creators of the Galaksija project, who shared some less known facts about the history of the Galaksija and its

Sourcing a replacement iPaq 3600-series battery

A few months ago I got a Compaq iPaq H3650, the same model that I had almost twenty years ago. This device left a strong impression on me, so even though I had (unfortunately) long ago gotten rid of my original one with a broken screen, I wanted to remember what these strange proto-smartphone devices were like. I got an iPaq on eBay for $10 (Pocket PCs are apparently not

Designing custom characters for the Galaksija

Galaksija computer stores its characters in a separate 2716 Character generator ROM. While these characters are fixed in the ROM, you can easily design new characters and burn them onto your EPROM. This article will cover how the Galaksija characters are programmed and where to find them in the character generator ROM. Each character is 16 bytes, or 8 columns by 16 rows: Each character consists of 16 bytes which

Yugoslav IEVT TY key switches – SMK style switches in disguise

Back in 2020 I built my first Galaksija computer, using the original single board design. Building this computer was quite a challenge for me, as I was pretty inexperienced with electronics. But the most difficult challenge was finding compatible key switches — so difficult actually, that it took me almost 3 years to find the right ones. This short article describes this journey, as well as a brief history of
