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.
Just a quick note. While you can buy (when in stock) my video mux to get composite, and S-Video in COLOUR out of the VDC, I am working on a new scan-doubler board. The MUX simply turns the VDC into normal RGBs/Composite/S-Video for use on old monitors, it does it REALLY well though. www.pyrofersprojects.com/blog/product/c128-video-mux/
It looks terrible at the moment as it's a messy mock up of wires everywhere. When the PCB is properly designed I should be able to clean up the image until it's almost perfect and you would swear the 128 is native VGA out
Its not DB9 OR 8pin DIN, the 128 outputs both and they are different, you CAN NOT get 40col games, C64 mode etc on the DB9 port. The 80 col output is separate from 40 col and you will need screens that show BOTH to use the 128 to its fullest. However for most things you will be using the 40col output, unless you are looking to use GEOS and other productivity software which works with the 80col mode.
A PAL 128 is always PAL (even the VDC is different on PAL ) to NTSC. However most NTSC software will probably work fine on your PAL machine, the music will just be a bit slow. If it doesn't work on PAL there will probably be a PAL version of the software or a PAL fix, the PAL version is the dominant version and NTSC software is a lot harder to find. If you do find a piece of software that is NTSC only and there is no PAL version, let us know and we will make a PAL fixed version.
