I am putting together an 8-bit CPU-based computer which is to have a
colour video display. In my research on PAL video timings, I notice
that the vertical sync is a series of pulses. If I am just using a non-
interlace display, do I strictly need to have a series of pulses?
I have made a TV-based video display in the past and just used a 192uS
pulse every 20ms as VSYNC. This seemed to work ok but I am wondering
if it's actually important to have the series of long and short VSYNC
pulses.
