Q: I pressed the Program button and everything started ok, but suddenly got stuck at 1-2%? Also im getting a "Error at 0x0001F3 Chip = 0xFF Buffer = 0x18" ? (or similar message).
A: Supply voltage seems to be to low (step 6). Check that the jumper is off so you get the full 6V. Note: you can do this while the power is still on, and save your burn by repressing the program button .. it should continue programming the rest of the chip.
