The Pepsi Grand Slam matches are on the ATP site now as "official" Kiki. Gizo, great thread. I was just thinking about trying to really look at all the official and unofficial matches played by Borg during 1976-1981 at the very least. In the past this was not an "official" tourney, but now it's moved into that category on the ATP site. Thank you.
For example, see Borg's "official" record in 1979, which includes the Pepsi Grand Slam now. (an invitational for players that have won a major, with big prize money and keen competition): http://www.atpworldtour.com/Tennis/Players/Bo/B/Bjorn-Borg.aspx?t=pa&y=1979&m=s&e=0#

(Thanks Krosero for the video upload.)
I can never understand why the Pepsi Grand Slam is official with basically 2 rounds and the European Community championship in Antwerp with all its rounds is not official.
