Can you help troubleshoot this Aquarius RGB mod?

[towmater]

I'm using the Crayon King's RGB board, which I think was actually meant for the Intellivision, but works (almost) perfectly with the Aquarius, except the vertical sync. I can basically short the sync-on-green jumpr to force a random vertical sync position, but there ought to be a correct way to do this? At top is HDMI, Bottom is correct RF display.

Neat. Yea I made the code for the Aquarius and briefly sold them. The listing went away and I sort of lost all the install instructions. I do however have the code for both the rgb/component board (baked potato) and the composite/rgb/svid board (orange peel).

 

The code for Baked Potato was tested pretty extensively so that is probably the way to go for now.

Orange Peel is good if you want one of those other outputs or to use the SEGA RGB cables.

I did write the code for OP but cannot remember if I tested it...The thing with OP is some consoles work better (look better) running a master clock of 2x the pixel clock; I am almost certain this was one of those consoles that needed two clocks to the OP kit.

 

I believe both versions of the Aqua kit have an Intellivision color pallet programed as one of the options.

 

I wrote the code for the Intellivision and the Aqua completely separately. As in I didn't realize there was any correlation. This raises a lot of questions.

 

Anyway, ignoring my deep curiosity of what exactly you have done here for now...

 

To answer your question Im not sure if you can make component work here. To make that kit work (without me reflashing it to use the Aqua code I have); the kit probably needs its sync input tied low (or possibly left attached to whatever it currently is); and instead get sync for RGB output from a different area. Bypassing sync through the kit entirely.

 

The reason for your issues using the Intellivisions code is that sync is retimed to work on the Intellivision (to fix its broken sync). So this retiming is goofing up syncs functionality. The main correction is happening around vsync which is why you have rolling video Id guess.

 

 I will remake the listing eventually I just got really busy with non console things.

Thanks for the insight. I ended up removing the modulator, then tying the old channel switch to ground the sync-on-green pin as needed. By toggling this a few times, I can find a good un-split sync position.

You could also try sending the 3.54mhz clock instead of the 7 mhz one.

I think the instructions for the Aquarious mod attach at the 7mhz but only because it looked better than running off the 3.54mhz. The sync correction is timed off a 3.54mhz clock. I still have no idea how you have wired this or how the Aquarius correlates to the Intellivison exactly.

For example most of the sync pulses were V5 and V1 being 1 on the Intellivision. I don't know how that works at all on the Aqua.

Anyway, not to double post. But I thought I should re-clarify I do have an Aquarius mod I just had the listing deleted at some point and was too lazy to remake it (since the info is spread out all over the place).

This was the OG post https://forums.atariage.com/topic/322600-aquarius-rgb-mod/#comment-4858455

 

Here is the replacement listing for it: https://www.ebay.com/itm/285171640870

I just thought anyone else stumbling upon this thread might want redirected to the kit's page intended to work on the Aquarius.

 

I am still not sure what @towmater did to make the Intellvision kit work on the Aquarius in the first place. Since AFAIK the connections from one console to the other do not correlate?

You can kind of see it at the bottom of the picture... that is an INTV board, isn't it? I can't remember for certain.

All those boards look identical; since only the code internally changes
