Gerbers and .CSPcbDoc (PCB file for Circuit Studio) for the 2-layer version of Galaksija.
Based on the original layout, with 3 modifications:
1. There is top layer, which replaces jumpers (at the same positions as jumpers)
2. New connectors which can be directly soldered to the PCB (no wires)
3. 5nF ceramic capacitor added between -RFSH and GND pins on Z80A. This solves the problem of modified timings on the CMOS version of Z80A (may require experimenting with some other values)
