ATMega644 Galaksija
Electronic schematic
As you can see the schematic is extremely simple and in a few minutes everything can be connected on a proto board. The circuit generates a composite PAL video signal as with the original Galaksija.
Finished electronic circuit
This is how the circuit I made for testing looks like. The same circuit was used for ZX81 emulation.
In operation
Video captured directly from composite output.
