    Once again about "TURBO" in SCORPION ZS 256.

good, but the brakes are terrible. And I sat behind him
exactly three years and couldn’t do anything.
But somehow this magazine came to us like

they cost much worse because  BORDER  on top and
below really 224 clock cycles are drawn, and
the screen itself is drawn less than  128 so-

between interrupts at SCORPIONa approximately
69888 ticks = 312 lines * 224 ticks. Yes, yes
