The commercial used "old-school" C64 programs - the Write Stuff 64 with built-in Busy Bee Talker (S.A.M. - Software Activated Mouth) and the Flexidraw hi-res drawing program.
I tried to get it at the 1-minute commercial limit, but the closest I got was 1 minute, 9 seconds. If I took out all that "business" before the C64 got going, it would definitely make the 1-minute mark.
