Notice how narrow the old pit lane was too, there was no stop box or pit lane speed limit either in those days.

I remember kneeling down trying to fix problems like some of the guys seen in those shots, and if you had a pit near the top bikes would be coming past you at over 100mph just feet away from you heading down to their pits near the bottom, likewise if you had a pit down at the bottom they would be accelerating past you from the top end at a similar speed, it was a scary place to be!!
