  1. a.k.a. cursing ffmpeg and deciphering ICCVID.DLL while dreaming of building a youtube proxy Here's what I have so far, using a 15 second test clip and cinepak compression ffmpeg's implementation of cinepak is far too slow to be usable for on the fly conversion, running at approximately 0,2x realtime. That said, I documented my working configuration here: https://welcometomacintosh.neocities.org/notes.html Mencoder's VfW wrapper doesn't implement core features of the VfW API which results in the Radius Cinepak codec shipped with windows creating unreasonably large files. I submitted a bug report about the lack of quality selection, but will need to submit another about the inability to specify a target bitrate and forced keyframes, as what I've discovered depends on all of those features. So, using virtualdub on windows 10 I got to work fuzzing out the radius cinepak codec. All the files I've created are named in the following manner q(n)k(n)b(n).avi where q(n) is a quality from 0-100, k(n) is keyframe every (n) frames, and b(n) is target bitrate in kbps. Interestingly, none of these numbers are actually correlated to what they supposedly stand for. First off, if k is 100 or less, q has no effect whatsoever on the video and a lower b paradoxically raises the filesize by a few kB. A lower k value will also increase filesize by a few kB unless it's k=0 at which point it produces a massive file. However, at k=101, q starts to mean something. q=0 produces a file that is an order of magnitude smaller than q=100. Values between 0 and 100 then scale the filesize and resulting video quality like you'd expect. b meanwhile no longer affects the file size or video quality whatsoever. Why it doesn't use the requested quality value unless keyframes are spaced 101 or more frames apart is a mystery to me. Here's a link to all the videos for comparison. https://drive.google.com/drive/folders/1XYrTXgbMETGJ4fx2CBvUGFiSxmOSB0-Z?usp=sharing

    ADC video card that works for 6400 ?

    So yes, the 32MB Radeon 7000 issue has to be some sort of firmware bug or limitation as it fails to output 1920x1200 over its dvi port.

    RAMDACs shouldn’t affect DVI output tho, should they?

    Considering the 16 MB Rage 128 in my 7300 can push 1920x1200 I’m sure it’s a firmware bug of some sort.

    Someone with more experience than me wrote an entire article about it. http://www.synack.net/~bbraun/ati7k.html

    You can also put a PCI Radeon 7000/Radeon VE in a 6400, which gives you DVI, VGA, and S-Video. I have a 64MB VisionTek brand card flashed for mac in mine - the brand is important because most PC cards don't include enough flash for the full mac rom, afaik only the 64MB visiontek and some sapphire cards have the right flash chip.

    G4 Cube Monitor Support

    I'd be interested to hear what you come across for polishing the cube. I've been working on mine (which has a spot of fogging on the inside from either acetone or CA glue I assume) by hand using Meguiars ScratchX and PlastiX polishing compounds, which are my usual go-to for restoring glossy plastics and it's working ok but I'm nowhere near an expert in this thing. It's hella slow going doing it by hand, but I couldn't get a random orbit sander with a buffing pad down inside the body and wouldn't trust it not to melt the plastic anyway.

    G4 Cube Monitor Support

    Geforce 2MX is generally the next option people choose. The cube specific version is just as much of a unicorn, but the regular Mac version apparently works with active cooling, or you can use a Geforce 4MX or ATI Radeon 9000 if you relocate the VRM, fabricate a custom face plate for the card (or go without and be real gentle) and add active cooling. Here's a macrumors thread about it: https://forums.macrumors.com/threads/g4-cube-gpu-upgrade.2030782/

    Of course! I hope you have all the fun with your cube, it's a gorgeous machine. Also, be extremely gentle with the kickstand on the back if you buy any apple monitor of that era. My 15" LCD studio display has a broken stand and all I did was look at it wrong.

    G4 Cube Monitor Support

    A stock cube will have a single ADC port and a single VGA port. That monitor will connect directly to the ADC port without any adapters - the ebay description is describing a different monitor than the one pictured. The DVI-D to ADC adapter is only necessary if you plan to put a graphics card in the cube that has DVI out in place of the ADC port. That said, it's nice to have as those monitors require that adapter for any system that doesn't have an ADC port.
  11. Just echoing that SSDs are worse than spinning disks when it comes to backwards compatibility. I know for a fact that newer PNY and LiteOn SSDs also don't work in my G5s, so cheaper brands aren't any better.

    I haven't tried making a paste of it, no. That's a good idea!

    Performa 6200CD needs an ethernet card

    Of course a month after I gave up on finding any CS1 ethernet cards and just bought an LC PDS card for my 630, someone posts an ebay link to multiple cards at a reasonable price. Definitely go for the comm slot card if you can. I'll just be over here kicking myself. :p

    Corgski's liberaciones para la revolución

    I was wondering what was up with that, there was a tiny patch in the top left corner still. I'm still researching what I can use to remove the masking tape residue - WD40 didn't touch it, and I'm hesitant to use plastix and scratchx like I'm using on the cube since the monitor's bezel is textured. Oh, and good news, the wonky USB ports on the 23" cinema display was just a couple of bent pins. USB is still sketchy plugged in through the DVI adapter, but it's working perfectly on my G5. As for today's conquest, my fiance and I have been cleaning and I found his original iPhone Model A1203. So now that's on my desk to clean up.

    You'll want an LC PDS card, for example in this ebay listing from @maceffects or a comm slot 1 ethernet card, but those are extremely rare. CSII cards will not work in the 6200's comm slot.
