I have a Commodore 128 DCR and I have to use the 80 columns but to HDMI or at least svideo. Now my questions are:
1.-I want to use the DE-9 pins port to output the 80 columns. But what is the best way to output that signal and transform to reach svideo or HDMI at the highest quality and no loss of color or anything to see in a TV or monitor HDMI.
2.-The commodore 128 DCR I have is in PAL, now using the Output DE-9 pins is important the issue to load a PAL or NTSC game that can affect the svideo or HDMI signal? For example if I run a game in NTSC can I play it? Or everything must in PAL 100%
3.-If there is a problem running also games in NTSC in the PAL computer? What can be done to run NTSC games?
4.-Using the port DE-9 pins, I know the C64 mode, supports only 40 columns, then the question is can I see the 40 columns video in 64 or 128 mode via the DE-9 pins or Inneed to use the port DIN to output the video from there instead the DE-9 pins for 40 columns in c64 or c128 modes?
#1. If you want S-Video see my article here. Another alternative (you did not request) is VGA... I have my original and new article about VGA. I mention these because you can use commercial VGA=>HDMI adapters... and because I do not know of any direct C128|VDC -> HDMI adapter. (if anybody knows, please post!!) #2. I don't understand... the DB-9 output does not care if video game is NTSC or PAL (now the monitor you connect may care, but that is a different issue!) #3. Either your monitor will accept NTSC video or it will not... you might be able to buy/build special PAL-NTSC converters for your monitor... but the major issue is "playability"... games designed for PAL will often play too fast on NTSC machine (very difficult or unwinnable) and games designed for NTSC will often be slow on PAL machine (easy gameplay). #4. If you are running C64 games, you will get no useful output from 80-column/DB-9 port.
