One of the few times I find something on the cheap, and it’s in excellent working condition... C= 1702 monitor. I am really surprised how good the video is on this, even using composhit output. I don’t have the separate Lima/chroma cables for a C64, so as to get SVIdEO, so, I reckon I’ll go ahead and make myself one, for even sharper video. Got it for $25 from a guy who’s owned it since the ‘90s, and was happy to see it go to another old dude with a retro fetish.

Dude. *Nothing* looks better above a breadbin. Well. Maybe 1980's Kelly LeBrock, but that's a different matter altogether.

...and definitely not under a 2019 Kelly LeBrock poster... *shudder*

So, today I did the SVideo receptacle mod. Since the 8 pin Commodore Video port has separate chroma and luma outputs, and, this monitor supports those inputs natively, as well as composite only, why not do the mod if you’ve got some spare parts lying around? :)

One could build an adapter cable using an SVideo female and two RCA males, but, I’d like to keep my cable and Adapter “collection” to a minimum.
This came out very clean and almost looks factory.

The video improves noticeably, even though composite is VERY good on this monitor. It took about an hour to do, including disassembly, desoldering, desoldering, and reassembly.

Oh that's very very nice. The c64's composite signal is definitely above average, but getting the luma and chroma separation is phenomenal. That mod is super clean too.

Did you do that mod on your own, or did you follow some instructions for it somewhere? That looks fantastic. I know some folks that might want to follow in your footsteps...

I knew it was possible to do for quite some time now. A good guide for it can be found here.

I did mine without the hot-glue snotfest, though :) Mine is held in via a "bulkhead style" of fitting, with a nut that retains it in place instead. Also, I used a PCB to adapt the wires to the SVIDEO plug, that I had lying around from a NESRGB kit I had installed into my NES a while ago.

Completely amazing. Whenever you go to a retro computing event the 1701/1702s always look the most vivid. I will hold onto mine until it dies (which will be a very sad day indeed).
