I recently got my hands on a Galaksija kit from the official website (https://galaksija.org.rs). Since I was in Serbia soon after, I met with Aleksandar in Novi Sad to pick it up in person. This coincided with our trip to Belgrade, where we were visiting old friends.

The Iskra Delta Partner computer supports vector graphics and has the capability to draw green lines on a black background. When porting a game from an 8-bit microcomputer with full colors to the Iskra Delta Partner, you have the option to manually create sprites based on color sprites. Nevertheless, there

Retro computer games are characterized by their vivid visuals, featuring flying spaceships, blinking rocket thrusts, falling meteors, bullets soaring through the air, and explosions happening all around. The elements in these games can move at various speeds, and while the effects are temporary, the gameplay itself remains constant. In this

In the realm of vintage computing, uncovering the secrets behind a faulty machine can be an exhilarating journey. Recently, I had the opportunity to delve into the inner workings of an Iskra Delta Partner (IDP) computer from 1987, which was plagued by random crashes and an endless boot-up loop. In

A year or two ago, I came across a Trident computer being sold by a collector in Bosnia. The computer was in a less-than-ideal condition, missing crucial components like the PSU, hard disk, floppy disk, RAM board, and operating system (or any kind of software for that matter). Undeterred by

I recently acquired two Ines keyboards from a collector in Zagreb. These keyboards were produced in the 80s by a Slovenian company called Inštitut za elektroniko in vakuumsko tehniko (IEVT), which still exists today as Tipro. I restored the first Ines keyboard and documented the process.

Iskra Delta Partner is a series of personal computers that were manufactured in Yugoslavia in the 1980s. In this blog post, we will explore how a Partner (specifically, the "GDP" version) can be connected to a PC using a serial connection. First, let's take a look at how the I/

Recently, our team was presented with a unique challenge - retrieve data from 30-40-year-old floppies that contained data and programs for Dialog, a relatively rare Slovene computer. Despite the odds, we were quite successful in the task. To retrieve the data from the old floppies, we used Kryoflux - a

Hi there! If you're into Z80, finite state machines, or CP/M, you've come to the right place. In this example of a not-so-simple Z80 finite state machine, we're showcasing the implementation of an CP/M path parser. In this demonstration, we'll be parsing a CP/M path that includes

A well-planned design can make your job a whole lot easier. Just take a look at how this case statement in assembly streamlines things, for instance. ld a,(hl) cp #' ' jr z,is_space cp #'_' jr z,is_underscore cp #'$' jr z,is_dollar
