Vintage Mac Community Begs Manufacturers for New Supply of Rare Dongle as Resellers Charge $250 (404media.co) 77

Members of the vintage Mac community are in desperate need of a new supply of a specific, discontinued dongle that has become increasingly rare and extremely expensive on the secondary market. From a report: "Bring Back the Belkin F2E9142-WHT ADC to DVI Cable for Vintage Apple Macs!," a change.org petition created this week by vintage Mac enthusiast Grant Woodward reads. "I am deeply concerned about the discontinuation of the Belkin F2E9142-WHT ADC to DVI cable. This essential piece of technology has become increasingly rare and difficult to find since it went out of production," the petition reads. "For those unfamiliar with its significance, this cable allows vintage Apple Macintosh computers to connect with more recent monitors, breathing new life into these iconic machines. It is an invaluable tool for restoring, collecting, and preserving these pieces of computing history." As Woodward notes, the adapter in question allows an older generation of Power Mac G3 and G4 from the early 2000s to connect to newer monitors.

      From the article, it's just a passive connector so this is really just an adapter, I wouldn't even call it a dongle. Learn how to strip some wires and make your own if you really want to keep using your awful early-2000s Apple technology.

      • So a 3D printer and some epoxy should get you a fragile but usable part.

      • From the sound of things it seemed like the dongle had custom chips or some bullshit inside. All they need is a connector cloned? I can probably find some company on Aliexpress to do it.

        • Doing some very light research, the Apple Display Connector is DVI plus power plus USB. It uses the same pin arrangement but a different shield (round ends instead of trapezoidal) to prevent you plugging in a normal DVI to the custom socket and blowing something up.

          If all you need to do is adapt the mac ADC port to DVI, then you just need a passive adapter.

          Going the other way might be trickier, since you'll need at least breakout cables for the USB and power (with external power supply).

          ADC is a 30-pin and DVI is a 24-pin. You can coax an old projector DVI standard DVI-M1 into fitting a ADC port. So if you had to rip heads, DVI-M1 is a start. Minus that, best to press your own with epoxy or 3D printing if you're into that new age stuff. However, I don't know anywhere off bat to find the metrics for spacing and what not, I'm going to guess seeing how DVI-M1 fits mostly that the spacing is the standard 1.905mm across 10 units for 17.145mm (there's 0.9525mm on either side of the 1 and 10 pin on DVI-M1, so 1.905mm*9 [massive air quotes] basically [end quotes]) for the the full width. [highlighting_here] (ISH) [end_of_highlight], I do know that the time I did it for a friend the pins needed a bit of "coaxing" to slide into the port on the monitor, so either I suck at cutting heads and squeezed too hard (which is very likely) or DVI-M1 and ADC aren't "prefect interchanges" (also likely).

          But that said, that's been years ago. If you can find a ADC head, you can literally just follow this guide. [lookanotherblog.com] No need to bake your own heads. And also, don't quote me on shit here, because the time I did all of this was under the influence while hanging with friends and was basically an awesome way to find out that you shouldn't use a soldering gun while that far removed from a clear mind. Or maybe that's exactly when you should use one if you don't mind nicking your finger a few times. I don't know, I'm just relying personal experience here, there are no refunds if this advice leads to your toaster trying to kill you in your sleep.

          You can get 67 Shelby Cobra replicas. You can even get parts for the originals.

      Yup, same with the Atari 8-bit community. There are several options to get DVI out from the old Ataris.

      For one solution, someone designed and ordered small custom circuit boards that are the same dimensions as the old 40-pin chips. The board is populated with a FPGA and other chips and plugs into the socket for the GTIA graphics chip. The FPGA re-implements the chip it replaces and the board includes a header for wires to a DVI connector.

      Of course, the community ran into problems when supply chain issues resulted in small projects like this having trouble getting them built.

      But, yeah, the community may need to step up and build new parts. With 3-D printing, obsolete connectors aren't a problem; people print Atari cartridge cases and SIO connectors. The biggest problem is having someone in the community with the time and knowledge to make it happen, which depends in large part on how large the community is.

Personally, I think they should have done GTIA on the 800 and CTIA on the 400.

    Fucking eh, took me ten seconds on Google to find someone who has already built one [lookanotherblog.com] for about $35 in parts. And it's not like the wiring for ADC to DVI is some impossible to understand thing. There's already a pinout for the two up. [pinoutguide.com]

    This is the deal with vintage hardware. If you want to keep old shit, you're going to have to learn something about wiring, maybe software, and so forth. Basically, if you want to keep old shit around, you're going to have to become your own support team. I swear, some Apple users.

      That blog post is thirteen years old. The trick nowadays is getting the male ADC connector, which are no longer available. Making a new one would be very hard without the proper tooling or some expensive prototyping machines.

      Agreed, though: Collecting vintage computing gear may involve sourcing rare, expensive things.

        From what I could find, the ADC connector looks like a normal DVI connector with a different shell, and some latching. Given that the shell doesn't need to be 100% intact in order to function both mechanically and electrically, it wouldn't seem such a big task to modify a DVI connector to fit ADC for someone who is able to rewire them so the signals match. Without one to try it myself, it sure looks like if you cut off the short ends of the shell, and maybe nibble off a little more, put a crease in the mi

          The ADC connector has more pins, but the extra pins (assuming you tried to re-use a DVI connector aligned from the analog pins) are for power and USB, which would not be relevant for connecting a retro mac to a modern monitor anyway. You may need to rip off the shield and dremel away a bit of the plastic from the DVI connector, but other than that, as long as the pin spacing is the same (I can't tell, it looks like it might be) then you should be able to modify a DVI connector to fit and wire it up to adapt

          You'd be wrong. Different pins size, different pin numbers, different spacing, different shell, different latching mechanism. About the only thing that is the same is that both connectors contain metal, PVC, and wiring.

      • Find out where all the dead/broken Apple Cinema Displays landed up in the ewaste stream and cut off the connector from those.

      Good, now try and actually do it. Follow the instructions and let's see how far you get. Hint: Start with the fact that he's buying a ADC connector from a surplus electronics shop which ... doesn't sell them anymore (which isn't a surprise since the blog was published in 2010).

      Now actually go and look for an ADC connector. Not just a listing, but one that is listed "in stock". Then look at the price and suddenly you may realise what TFS is actually about.

      • Good, now try and actually do it.

        LOL Have done so. Actually have done a 16-bit CPU with TTL on protoboard back before wire wrapping was bespoke. I've restored a Revox A700 with their wonderful Frako capacitors that are always so nice to all the components beside them. So doing up a ADC with some smashed AWG20 and epoxy would be a cake walk.

          Seriously? I've got a pretty fucking good idea what it's about.

          Clearly you don't. Posting to a 13 year old article which proves the point given that the source of the connector doesn't offer it anymore. The connectors are selling for 150EUR upwards where in stock.

          Get a clue.

            As I already indicated, you can use a DVI-M1 to make do if you don't want to 3D print or pour your own. Like I said, if they can't do bear basics for vintage computing, this ain't a hobby for them. If they choke on the inability to have a header for a passive connector, fuck they're boned should they need to do a swap on any of the caps on the board or if EEPROM bits start flipping. This kind of shit is maintaining old hardware 101 and they can't even do it.

      no they are not going for that much, I looked on ebay there's oodles of them and the official Apple adapters that sold for 20-40 bucks. I don't know where this hack cherry picked their one example, but from the picture it looks like a scam page, probably selling portable air conditioners and free energy devices

  • Why are you trying to connect it to a modern one in the first place? There must be one that still works or could be repaired sitting in a barn or recycle shop.

  • Too bad Redmond Cable are no longer around, they would have whipped one up for folks for 1/10th the going rate.
