15.7 KHz RGBs to Component (YPbPr) schematic/IC?

Yes, likely sync on Y. But you don't want to *strip* the sync, you want to do the opposite, to ADD the sync.

You already have the composite sync available to use on the separate pin from the source equipment. You just need a quite simple circuit to impose the H and V sync pulses onto the Y video signal. The circuits I've seen for this have used a single transistor and 3-4 resistors.

No, I think you're nearly done.

I will make a suggestion now. Take your existing cable that fed the Commodore monitor, and feed that into the silicon chip box or equivalent, and feed that to the new TV and you are done.

Hi Petrus,

80 characters on a TV like screen is difficult to read, 40 works fine. If the characters are 8 pixels width, you have 640 samples in about 60 us.

OK, check your mail at hccdotnet. It has some verilog code, and a link to diagrams.

Got it, thanks.
