@@Codeaholic1 It's probably using dedicated counters/dividers and interrupts on the SoC to generate the timing rather than CPU instructions due to strict timing requirements of HDMI, so it probably could run on a slower CPU if it had the same counters.

@UpLateGeek 3 года назад

If you're happy to have the RGB2HDMI external, you could sneak a ribbon cable out through the kensington lock slot. You'd probably want a more secure connector for the wires internally, otherwise it would be super easy to yank the cable loose. Not to mention it would be a lot easier than having to figure out which pin on the cable connects to which wire coming from the analogue board every time. I definitely found the integer scaling much better than the interpolate 4:3 soft option. You can really see the difference in the diagonal lines of the arrows on the scroll bars, it's definitely blurring the edges/corners of the pixels together. Anyway, great job! Always good to have another tool to show off these machines in your videos!

I did a test capture from my LCIII using minimum System 7.5 about a year ago. I used a DB15 to VGA adapter out to a powered VGA splitter from DTech. One side goes out to my flat panel VGA monitor (so I can see the native output) the other side goes to a Star Tech VGA2HDMI box. It’s like a headless VGA monitor and supports a lot of resolutions. The HDMI of that goes to an El Gato game capture HD The old one, I don’t need to capture old Mac video at 60fps. The El Gato goes into my MacBook Air. The video is on my channel with links to the tools in the doodley-doo. Not quite as cool as this but I can’t solder. My setup is quite similar to what LGR uses except for the splitter. And he has (at least he did) an AverMedia capture system. Nice job.

It would be great if you can get one of these RGB to HDMI Raspi hats as a blank PCB and build it from scratch. As I understand, it self programs the CPLD when you assemble the hat yourself and power up for the first time. This is a great project and being totally open source, it is a huge contribution the the retro community. It really deserves to have an in depth build + review video from all of the best retro channels, and none that I follow has done it yet. IMHO, you should be the one to do it. I will be building a "Superfo" Harlequin 128 v4A board from scratch very soon. It is the last version of the "Harlequin" series ZX Spectrum 128K clones which uses all off-the-shelf 74HC logic IC's to re-create the long time obsolete custom ULA. The board natively outputs RGB and I am planning to use this RGB to HDMI project with it. I know I would be grateful if I saw a build video before I attempt to build mine, I am sure there will be tons of other retro-heads like me who would appreciate such a video. There is some fine pitch SMD soldering involved but with correct flux and iron tip, it is really much easier than one anticipates. Please do this. :-)

2:25 - I've mentioned before - external displays did exist for this form factor Mac - it connected via the SCSI port, expensive, but it worked! (Oh almost forgot the Mac SE 30 had a a few riser cards upgrades - there was a knockout on the back for the video output port (It was normally used for ethernet ports), I still have my Radius card & monitor!)

Now I have to see if I still have my TRS-80 (Model 1) in a box. This may be the monitor replacement I have dreamed of!

I used to work on a Mac Plus with an external Radius full-page display in 1986!

How amazing is this! The video capture looks like something I've seen emulated on my monitor, but it's being run from a real classic Mac! I've been following similar rgb2hdmi projects in the Amiga scene, but seeing it here on a Mac gives me an idea. It's probably beyond my skill level (I've done basic recapping etc), but I have a Color Classic II whose CRT is really bad and looks like it's on steadily for the past 20 years. In the right hands, a project like this could be used with a new internal LCD on the Color Classic II much like Noel did with his Amstrad CPC. The only problem I would have is, it would ruin the originality and aesthetics of the machine. The trinitron crt Apple used on the color classics have a distinct, flat curve to them. The LCD would have a wonderful picture, but look completely out of place in the housing I think?

I simply adore, how greatly technologies advanced over 30 years or so, and the fact, that raspberry pi convertor has over 500 times more ram, than the macintosh

I like the idea of replacing dangerous CRTs with nice friendly 5v LCD screens. Another nasty bugger, was 8 inch floppy drive. Those ran on mains voltage. All electronics from back then remind me of movies, where some lady spills milk and gets electrocuted by a blender.
