µGALAKSIJA started as a tribute to the “forgotten” GALAKSIJA computer, designed by Voja Antonic in the early 80's. The idea was to use pure FPGA design to achieve near 100% hardware compatibility sticking as much as possible to the original design, and maintain 100 % software compatibility (even when changing/adding something to the design). And, we did it !
We proudly present µGALAKSIJA, in all it's glory!

The design was changed (several times) during the project, so you might notice some “unnecessary” details on the PCB – like the never-used SD-connector layout. There was an idea to use SD for external storage, but later we desided to use the internal FLASH memory on the FPGA as a non-violatile storage for memory snapshots.
Several features are added to the “original” design – like the posibility of displaying 8 RGB colors (not related to any of the existing GALAKSIJA hardware solutions). There are two distinct methods implemented. The first is changing the overall display color, changing (default) white-on-black to color-on-black text and graphics. The second is a posibility of using a separate display color map allowing any low resolution graphics pixel to be displayed in one of 8 colors. (this also affects the character color by 1/6th blocks – so it is also possible to write nice colorful text).
