In this video i re-visit my C128 neo from last week and rip out the C0pperdragon component board and replace the Mbarszcz replacement modulator....
see this video for the modulator overview.....
• captain commodore ep8 ...
I have received a NEW board from c0pperdragon, this board sits between the vic and the mainboard and output just 2 wires to give PERFECT video through a RGB2HDMI........
This is the LUMACODE addin board which is available for several machines......

That looks SO clear. Gonna investigate it for my C128...

@CaptainCommodore Год назад

At the very least I can recommend the mbarszcz modulator as being the best I have used...... this lumacode board using just a simple rca means that a single rgb2hdmi can be easily swapped between machines for perfect video......

@retrotechinsanity Год назад

Holy shit, I'm blown away by how good that looks. I'm still going to attempt the component board just because I have it already but if it sucks I'll grab one of these.

@CaptainCommodore Год назад

It's a good one, I'm going to put the component in my "d" which has a stock modulator, that's pretty poor so I'm not going to sacrifice much svideo

@StatMatsVidz Год назад

Thanks for sharing. Night and day between this and the component board. If you want the sharpest picture you can get, this seems to be very best solution. Look forward to seeing it on the C64. :D

@CaptainCommodore Год назад

Yea, this is superb, I will certainly be chucking this into my c64,vic and atari 👍

@RudysRetroIntel Год назад

Great video and work!! A must see. Thanks for sharing

@CaptainCommodore Год назад

Ita a great board, and they are available for several systems , think c0pperdragons on to a winner here

@CityXen 6 месяцев назад

Pretty good, gonna have to invest in this

@CaptainCommodore 6 месяцев назад

The lumacode board works very well in the c128, however the atari boards have issues

@andreasimoncini 7 месяцев назад

Hi, congratulations first of all....I have a Commodore 128 and a Philips smart TV with HDMI output, my dream is to use my C128 with both 40 columns and 80 columns in RGBI and see them perfectly...not grainy or ugly but seeing everything in a nice and clean way for fonts and graphics is IT POSSIBLE????? Thank you

@robertholm773 11 месяцев назад

Looking good! I have a stock c128 with s-video to RetroTink Mini, then hdmi from there. Love it, but have jailbars ofc. Not sure how to get it as nice as yours?

@CaptainCommodore 11 месяцев назад

Well an easy upgrade for me was the mbarszcz modulator, but if you want perfect hdmi that has to be this board along with the rgb2hdmi, however there's a price difference.......

@carloscatano1750 Год назад

Fantastic!

@adamt3912 Год назад

Yep it's magic. I have RGBtoHdmi for 80 column too via an HDMI switch. C64 I can report just as good, a ropey C64G was transformed. Still feel this is the best solution cost wise... especially considering a framemeister in the chain..lag is supposed to be minimal too but would be nice to get some info on that.

@CaptainCommodore Год назад

Completely agree on the cost front, it's a good idea about the hdmi switch ( I too have the rgb2hdmi for 80col ) as the lumacode is running at a multiple of the frames peed to encode the data I would expect the lag to be less than a frame, will deffo try this in some of my other machines too 👍

@copperdragon9286 Год назад

The lumacode board introduces no lag. The individual pixels are generated at the same time as the original VIC-II would do that. To be completely honest, splitting all pixels into two samples actually causes the total information to arrive about one pixel later, but 120ns should really not be noticable. The RGBtoHDMI adds a bit of lag when upscaling but only about 1 or 2 milliseconds which is a fraction of one frame. So it really comes down to what your monitor/TV does then. I have a setup with a fast monitor and the overall lag is about 3ms. You really need an optical lag measuring device to be able to notice that.

@CaptainCommodore Год назад

@copperdragon9286 120ns..... Holy shit thats fast, I'm assuming it's just as fast for other machines except where's there's 6bit encoded will slow slightly (180ns? ) which is still almost undetectable......

@copperdragon9286 Год назад

@@CaptainCommodore Number of samples does not really make a difference, because they are just sent out with higher speed, anyway. This number is also just an estimate, but its about in the correct magnitude. Using an FPGA allows me to run everything as fast as the original hardware. If I really wanted, it would sometimes even be possible to generate the lumacode signal faster than the original chip.

@CaptainCommodore Год назад

@copperdragon9286 ahh , I understand, did a little fpga stuff a few years back, what's the practical limit rgb2hdmi wise ? Could this be used on ST/Amiga ?

@copperdragon9286 Год назад

Properly installed, the component board should work together with the RGBtoHDMI. You really need to connect the GND pins.

@CaptainCommodore Год назад

The 2 rear ground pins are ( were , i removed it now for lumacode ) connected to frame ground but from the underneath using a piece of kynar wire, I have the c64 version of this which works properly over the next few weeks I will make another video showing installation in the "d" I know it will be fine 🙂

@Barnaclebeard 4 месяца назад

Looks like an emulator, naturally.

@CaptainCommodore 4 месяца назад

Of course, But for me that's not a bad thing, looks very nice and although I couldn't get it to work I'm hoping a later version fixes the scan line generation
