  1. I was able to dramatically improve the picture of the CGA2RGBv2 & OSSC combination by doing a deep dive into the OSSC settings with help from VGP forum:

    Attached are some photos - it looks a lot better in person, for example none of the color fringing in the GEOS128 photo is present in person.

     

    Settings I am using:

    240p / Line2x

    H. samplerate 1016
    H. synclen 20
    H. backporch 241
    H. active 640
    V. synclen 3
    V. backport 36
    V. active 200
    Sampling Phase 11 degrees

    Thanks for the info!  The CGA2RGB can convert from RGBI to RGBs (https://gglabs.us/node/2063), and the OSSC can accept an RGBs signal.  I order a CGA2RGB to test with my C128 and OSSC. 

     

    Once I receive the CGA2RGB I'll update this topic with my results.

     

    Moe, what was the final verdict?  I'm trying to attempt the same - CGA2RGBv2 / OSSC / C128 in 80-column mode.  

    Any settings you had to tweak on the OSSC?  Thanks!
