Just bought Python Programming and GUIs book, I can't find the CD download image on Elektor.com. Anybody know where the download link is?

I've ran into a snag at Chapter 5 The Arduino Uno as a Slave
Specifically at Program 5-1 Use check buttons to select state of output
I'm unable to get prog_05_01.py "Write Digital Outputs" to toggle the 4 LEDs I have wired up to digital output pins 2,3,4,5.
If I execute prog_05_01.py in a terminal , clicking write gives the output:
(repeats 5 times ex tries 0-4)
"Incorrect address or project number for slave, project = 1 address = 1
failed to connect"
I never see tx/rx leds on Uno blinking

I have:
.. loaded slave.hex correctly (no error in log,)
.. set up user pi as a member of dialup group
.. fitted 10uf electrolytic capacitor between reset and ground
.. set slave address = 1, project = 1

My hw/sw setup is:

#1 Raspberry Pi 3b v1.2 ~2015,
OS:Raspbian Linux raspberrypi 4.9.41v7+ #1023 SMP Tue Aug 8 16:00:15 BST 2017 armv1 GNU/Linux
utilities: python3-serial 3.2.1-1, avrdude 6.3.2+rpi1, python 3.5.3 , incl tkinter

#2 OSEPP Uno R3 Plus ~2016, ATmega328P, (note avrdude detects device signature 0x1e950f, probably m328p )
