The Projector-3 programme sets the drives to doublesided in the BOOT.BAS 
programme:

0 'PROJECTOR-3 BOOT (DECB 2.1)
20 '
30 POKE55453,1
40 POKE55454,2
50 POKE55455,65
60 POKE55456,66
70 RT=0:SR=20
80 POKE55232,RT:POKE55318,SR
90 LOADM"P3"

Besides a mathematical inclination, an exceptionally good mastery of one's
