Request 6845/6847 Lumacode support

[oe7twj]

It would be nice to have a Lumacode solution for Motorola 6847 based computers.

This would include some homecomputers:

• Tandy CoCo1 and CoCo2 (https://en.wikipedia.org/wiki/TRS-80_Color_Computer)
• Dragon32 and Dragon 64 (https://de.wikipedia.org/wiki/Dragon_32,_Dragon_64#Grafik,_Ton,_Ein-_und_Ausgabe)

The CoCo 3 has much more colors with a newer video chip, I'm not sure if this is possible ...

But some old computers use monochrome CRT like the Commodore PET. The video chip used here is a Motorola 6845. If CRT dies the PET computer dies, it is not easy to get a new CRT. So this would be a nice methode to repair such computers.

The computers you mention already have good support by the RGBtoHDMI system when using a full analog input variant (not just luminance). Some will need slight modification of he computer. Details can be found here: https://github.com/hoglet67/RGBtoHDMI/wiki/Cables
