Mac Plus + RGB2HDMI + Sys6 Progamming + homemade stream? yes please

[Mu0n]

This guy hits ALL my checkboxes AND made his own repo manager under System 6 AND his own minimalistic streaming + chat program while he streams code sessions.

I want to be him when I grow up (although I'm not that far from him as of now...)

Hello!

 

[Mu0n]

Did you have issues with the occasional video glitch with your RGB2HDMI? My image is rock solid on my Mac Plus, but I'll have once-per-minute video twitches on the feed I get. I'd love to compare notes with your config file if you don't mind.

I didn't solder my wires into the J8 connector of the logic board, I just jammed the exposed ends of dupont wires into the white connector and since there's not a lot of space in there, they have to make contact with the wires that are already present. I continuity tested them and they seemed very obviously solid.

I don't think I've had any issues with that. I do notice that occasionally the Genlock LED blinks but maybe only every half hour or so.

I have 2 settings file:

Under the card's root dir (this one is used, it seems):
sampling=3,3,3,3,3,3,3,0,1,0,1,0,0,0,0,0,0,1,0,0,100,256,100,256,100,256,0,256
geometry=168,6,512,342,512,342,2,2,0,0,15667200,704,5000,370,1,0,0
palette=Mono_(2_level)
output_colour=1
output_invert=2
scanline_level=0
font_size=0
num_buffers=1

Under \Profiles\6-12_BIT_RGB ( I think I got this one from the net, I didn't like its palette)
sampling=1,1,1,1,1,1,1,0,0,0,5,0,0,0,0,0,0,1,0,0,100,256,100,256,100,256,0,256
geometry=172,22,512,342,512,342,2,2,0,1,15667200,704,5000,370,1,0,0
palette=RGB
output_colour=1
output_invert=1
scanline_level=0
border_colour=7

Do you have something similar to the first one?

I'm not sure which one it uses, profile_6-12_BIT_RGB.txt in the root of the SD card shows:

profile=Mac_Plus
saved_profile=0

The Saved_Profiles/6-12_BIT_RGB/Mac_Plus.txt file has:

sampling=1,1,1,1,1,1,1,0,6,0,5,0,0,0,0,0,0,1,0,0,100,256,100,256,100,256,0,256
geometry=172,6,512,342,512,342,1,1,0,1,15667200,704,5000,370,1,0,0
palette=Tea1002
contrast=200
output_colour=1
output_invert=1
scanline_level=0
border_colour=7
powerup_message=0

and Profiles/6-12_BIT_RGB/Mac_Plus.txt has:

sampling=1,1,1,1,1,1,1,0,0,0,5,0,0,0,0,0,0,1,0,0,100,256,100,256,100,256,0,256

Thanks for letting us know about @jcs And thanks for the content @jcs! I wish I found you like a year ago when I was looking into some c dev stuff!
