Hi there !
Unfortunately, I don't have this kit, but wouldn't it be challenging to write it yourself ?
Since this kit comprises only basic components, it wouldn't be hard to design your own circuits.
If it would help you, I have the radio shack 10 in 1 kit and has the exact same components. If you are interested, I could always scan this manual for you. So you can use this as a guide.
Perhaps Joustra used this Radio Shack kit and revamped it for their own brand.
Greetings
