Back in 1992 I bought the above named book.
Looking around in my (emulated) hard disk today, I found the source code to the programs. I assembled them, and found that they worked (which was a surprise, I must admit). For those who are interested, I have attached them, as well as the executables themselves.
I hope that some people might find them useful...
The WinUAE config was the Classic WorkBench A1200 Games
btw some of the executables are quit with the lmb, others with F7 - they're a bit flaky, you might need to reset every now and then
