Congratulations on the work unravelling the Delta-1 puzzle.
It seems like a further chess programming scandal has been revealed this time 40 years after the event. When Data Cash Systems lost their court case and appeal it looks like Novag/SciSys took another liberty and pirated a second chess program for use in one of their models. This time Boris for the Delta-1.
I have updated my webpage on the Delta-1.
