The supply voltage (+5V and ground (GND) you will have to get from the
Amiga's Expansion-Port or from a regulated +5V power supply. The GAL-Burner
has a maximum current consumption of about 220 mA.

The main difficulty in the construction of the GAL-burner is probably the
printed circuit board (PCB). Most likely a double sided through plated PCB
is required, so probably the best solution is to use a piece of v
