RE: [CAD_CAM_EDM_DRO] NTSC, was Re: 6 axis ARCNC100 CNC board with constant contouring turned on

I've got one of those new fandangled HDTV digital tv's.

It still has all the usual analogue UHF stuff, as well as normal base band
video inputs, video, vga, s video etc.

Most computer monitors will also accept basic video.

I would tend to agree there is plenty of time.

PS Lester, I don't get any HF QRM from mine, it's a Panasonic. Wife can
watch TV and I can play radio.

Most people will be using a set top convert for years to come even when
analogue TRANSMISSIONS stop. At the end of the day you still need
analogue somewhere on a CRT ;)

With an ITX motherboard not costing a lot, this will be the logical way
forward for expanding the range of interfaces - so there is no need to
build a vast overhead on a machine controller.
