I looked into vtvideo.c, but don't want to interfere with the VT100 code (no experience and no way to test on a live machine).
That said, i recently added 3 of the 5 character attributes necessary (reverse, blink, underline) - only for RAINBOW_VIDEO.Bold (intensity) and soft scrolling are not as easy to implement.
Additional to the 48 line mode (now also implemented & not present on the VT-100) there are possibly some undocumented DC012 pokes - see below.
Any info would be appreciated.https://dl.dropboxusercontent.com/u/37819653/SQUINT_Disassembly__POKES.jpg

---------Attached, you see a screenshot of a VR201 (orange-black) monitor connected to the Rainbow-100.
The combination of different attributes (bold + reverse characters on reverse base video) is a bit tricky to emulate correctly.https://dl.dropboxusercontent.com/u/37819653/rainbow-1024x768.jpgQuestion: what's the proper way to configure the palette to emulate different VR201 phosphor types (orange, white, ...)?
