There is string in source code "BOTTLE OF SOPLICA PIGWOWA". This is famous drink in Poland. So its kinda unpleusable that someone in 60" created its own CPU in garage in Poland at that time AND had the game on some IBM cards.

I think this story (about old game found in attic) is simply fake so author can brag about his "abilities" of decode some code - which he propably wrote...
