Most fastovy in my opinion adresya calculation on two
coordinates:
; B - X, E - Y
LD L, B; 4 takts
LD H, # 66; 7
LD D, (HL); 7
EX DE, HL; 4
LD E, (HL); 7
INC H; 4
LD D, (HL); 7 = 40 takts
Hence the fastest plot:
; B - X, E - Y
LD L, B; 4 takts
LD H, # 66; 7
LD D, (HL); 7
INC H; 4
LD C, (HL); 7
EX DE, HL; 4
LD E, (HL); 7
INC H; 4
LD D, (HL); 7
LD A, (DE); 7
OR C; 4
LD (DE), A; 7 = 69 takts
