oh I have been thinking about it sorta half hart, I am using a tv card in my computer, and it makes 80 col text impossible to read, growing up with the apple monitor II green screen I have never seen anything that quite compares to that heavy shadow mask and tweaked timing, even running it though a vcr (actually the pc tv tuner card is quite possibly the best i have seen an apple on a "tv")

the problem I see is that to adjust any analog video timing you pretty much have to capture it and then process it then output it, I dunno ill toss it on the o-scope tonight and see how different it really is, and with hard numbers in hand it would be easier to answer that question

no I am not a tv engineer, but I have been designing my own rs170 (B&W ntsc) system to use with microcontrollers and am saturated with video timing data (heck even made a vga sync signal out of a 556 timer)
