    Jeff is a legend. He has been able to create some custom C64 case saver parts. I've got a C64 case that has tabs that he has never seen before. He designed, 3D printed and sent me some prototypes that are 99% spot on!

    The HDI-45 video cable you have is extremely unobtanium. It was only used on Power Macintosh 6100, 7100 and 8100. No other machines at all, and was only supported by the Apple AudioVision 14 display. It was one of the attempts by Apple to mimic what NeXT had done: single cable between CPU (as in the computer unit) and the display, and having all the desktop stuff connect to the display. NeXT had an alternative too, the SoundBox, where you connect stuff to the SoundBox, which sits in between everything on the desk and the computer itself. They've been most successful with the Thunderbolt Display variety, and that's kind of doable on PCs nowadays too thanks to that.
    The cable you have is for Houdini and Houdini II cards and plugged into the 040 PDS slot on early Quadras and the special 601 to 040 PDS slot of the 6100 DOS Compatible. Don't trust Wikipedia on this stuff, it was not NuBus anything and was a 68040 thing although used on only two models of computer (Centris / Quadra 610 Dos Compatible and PowerMac 6100 Dos Compatible. Both had special slot adapters for it since normally they indeed had the 90° 040 PDS to NuBus adapter installed, but this card required a special 90° 040 PDS adapter AFAIK only used on these special Mac models. The card itself can plug into any early Quadra (except LC475 aka Quadra 605, which isn't a "real" Quadra but uses the 020/030 LC PDS slot instead even with the 040 CPU). I have my Houdini II card and cable in a Quadra 950 and had to search for a couple of years to find the right cable for it once I had managed to find the extremely rare card itself. I could loan it to you if you want to make a video on it.

      Yeah those HDI cables are difficult to find. Luckily I got one somehow shortly after I found my 6100/66. Even found the 1mb graphics card which is even MORE unobtanium.

      I think they had a little bit of success with the ADC connector in the early 2000s. There were several monitors that used ADC as well as (almost?) all the computers they released during that time. It was successful in that many people used those monitors and machines, but I don't think there were very many people who actually LIKED the connector.

    • @jammi__
      @jammi__ 3 роки тому +1

      @@StarkRG ADC failed along with AGP 8x, when suddenly Apple's proprietary use of previously "not connected" pins they used for USB and +25V from their motherboards to the custom AGP cards were used for extra AGP data pins. The most successful Apple proprietary connectors are Lightning, Mini-Displayport and the 30-pin iPod/iPhone/iPad dock connector. Out of these, Mini-Displayport has become an actual industry standard.

      I passed up on getting a Power Mac 8100 literally today specifically because of that 45 pin display connector. It had already been pillaged for the secondary PDS video card that I believe came stock with the machine.

    1:45 It's a video cable for the built-in video on PM 6100/7100/8100. It connected to the video that shared RAM with the main RAM. These systems, especially the 7100/8100, usually came with a separate card with its own video RAM. This cable was typically NOT included (at least with 7100/8100) and was hard to find and spend-y even back in the day! IIRC the cable to use the shared RAM topped out at 640x480 @65536 colours (thoudands) or 800x600 @ 256 colours. The card with full RAM expansion (it sometimes shipped less than fully populated) would do at least 800x600 @ 16777216 (millions).

    • @ray_mck
      @ray_mck 3 роки тому

      I never owned the PowerMac version, but the cable looks in the video to be identical to the older one for Houdini on the Quadra/Centris 610, not just the PM x100s.

  • @GarthBeagle
    @GarthBeagle 3 роки тому +34

    Yup, hard to find the original DOS Compatibility card cable. This one is indeed for the Power Macintosh 6100 or Quadra/Centris 610. There are plans available online to wire up and build your own.
    This DOS card in those systems were used with a right angle riser card (with a different connector between the PPC/68K macs) and the actual DOS card would fit into a PDS slot on that riser. You could actually use the card in other Macs with that PDS slot such as a Quadra 700 or Quadra/Centris 650, though the back of the card would not actually reach the back of the case, so you could run the cable inside via a slot.
    There were 3rd party cards too (Reply made some) and those cards were more for the Quadra/Centris 650. They came with an extension board that just extended that high density connector on a PCB so that it reached the back of the Mac.

      the 7100/80 also had the same built-in *ANTI-STANDARD* video connector; another crappy decision by apple, as no monitor was made using that connector, the adapter shown in this video was mandatory for all those early PowerPC Macs

  • @RonsCompVids
    @RonsCompVids 3 роки тому +3

    This cable is for the DOS Compatibility Card for the Quadra 610 and Power Macintosh 6100. The card will also work with the Quadra 700 (with a port extender) and a Centis 610 (without a port extender).
    This cable does not work with the 12" version of the Apple PC Compatibility Card. That card requires a different cable.

    Funny, literally to my left on my main desk is a 6116CD with the dos card in it and I am using that cable to an apple display. I have DOS on it right now and its on my to-do list to load win3.11, maybe next weekend. My mother in law had the 6100 in her garage and couldn't recall where it came from and I found a guy not far from me who sold a NOS DOS compatibility kit for $100. My father had the same setup when I was a teen way back. I think its a neat collector piece that I could load a lot of interesting software of the day, both PC and Apple.

    Oh, man. I just bought one of those video adapter cables for my 7100 a few weeks ago. I feel like I got lucky finding it. It even ended up being new old stock. I also have a Houdini card and the guts from the Quadra that it ran in, but I DON'T have the cable, and the last time I tried to find one, it was going for like $200.

    I used one of those machines back in the day. My employer bought one for the specialty toy store he owned. We had been using a Mac 512 which we used for making signage in the store along with all of our bookkeeping forms and did some high level accounting and then we switched to this machine. It fit perfectly with what we were doing in the store where we mostly did everything on a Mac but occasionally someone sent us something that needed to run on an Intel PC.

    It took me a few months to find to this cable and I paid nearly $100 for it. I really enjoyed playing with my 6100/66 DOS compatible but the SCSI hard drive failed. I need to get around to installing the SCSI2SD I got for it. Might have to be a weekend project.

  • @racecar_spelled_backwards868
    @racecar_spelled_backwards868 3 роки тому +4

    3:45 Correct. The card was designed to be a full-screen take over. It worked in practice kind of like the Apple //e card for the LC in that it took over the whole system while in DOS/Win 3.1 mode.

    Up until about a year ago those cables for the DOS cards were easily going for about $30-$50, then something happened that caused them to seemingly double in price overnight.
    I wouldn't be surprised at all if for most people looking to complete the set that this would be the last piece.
    It works but is a bit of a mess coming off the back of my 6100...I myself am still looking for the angled pds adapter to install it into a Quadra 610.

    I have one of the 12" PCI ones with the Pentium. It came out of a PowerMac 7200 PC compatible that used an internal cable to swap between the Mac and PC. One day years and years ago I found the proper external cable on Ebay so I was able to use it in my PM9600 which I thought was pretty neat.

    @BrianLedbetter 3 роки тому

    Just picked up a Power Macintosh 6100/610 DOS Compatible that has this cable, it's amazing to see how well this actually worked in 1995. The PC card boots off of disk images that are stored on the Mac hard drive. The system came with Windows 3.1 on it, but the manuals state that it's able to be upgraded to Windows 95 as well. (I don't believe it supports Windows NT, but as soon as I can image the hard drive and transfer it to a SCSI2SD card, I'm hoping to be able to try.)

    The Apple Macintosh Performa 630 (CD) (PC) features a 33 MHz 68LC040 processor, 4 MB or 8 MB of RAM, and a 250 MB hard drive in a compact desktop case. The Performa 630CD added an internal 2X CD-ROM drive and the Performa 630 PC-Compatible shipped with a 66 MHz Intel 486DX2 processor card which can have a maximum of 32 MB of RAM dedicated to the DOS/Windows operating system.

    The Bare bones Power mac 6100 sold for $1819 with the PC compatibility card back in 1995. The model with the PC the LGR showed sold for around $2100 according to Clint. That means the price difference was around $300. Now I don’t believe you could buy a complete 486 Win PC setup at that time for $300 new that would match what this card was offering for around $300, especially given this setup allowed for easier sharing of a single monitor, mouse, and keyboard between a Mac and PC. So I would expect this to be the better deal if what you needed was occasional DOS/Windows PC compatibility.

  • @Cowclops
    @Cowclops 3 роки тому +1

    I believe the cable with the big fat end is HDI-45. I got a power mac 8100 for free a while ago that had a video card with that end, and it needed the adapter to plug into the adapter. I agree with your assumption that its probably not that rare.

    Not really Apple related but an old 286 portable computer that is somewhat hard/impossible to find individual parts for eg the modem expansion and RAM cards for it, I’ve been working on creating my own stuff for it, scored a junked one on eBay (waiting on the second one I bought to come in) that just happened to have a 1meg memory card in it and have been reverse engineering that to figure out if I can make my own cards for it. If I could get the modem I could try giving it a second serial port or use the modem as is. The docking station I think would be ridiculously rare, I only saw one on eBay commanding a high price and would have given the machine a few ISA card slots and I think an extra floppy drive etc.

  • @matthewjbauer1990
    @matthewjbauer1990 3 роки тому

    I have read reports online that a complete setup 6100 with the DOS card would run somewhere around $3000. The card alone would cost about $1000. Anyone who was smart and wanted better performance would (should have) spend $500-$700 on a Packard or HP or Dell or Compaq kit. The only real reason I can see someone getting one of the compatibility cards is if you don't have the desk space or if you don't want PC and Mac at the same time on the same monitor. I think you could share files between Mac and PC using the card, but a properly formatted floppy or a network share solves that problem. I see an advantage to getting a separate PC, the ability to do both PC tasks and Mac tasks at the same exact moment without having to toggle the monitor. in fact, ANY compatibility card for DOS, whether it be for the Amiga or Apple, were flawed in that a separate PC was always a cheaper and better option.

    Instead of scrolling the Patreon names way too fast at the end why not simply extend the time they are displayed mkaing the display slower - in previous videos it was better to read.

    That plug looks like an original Xbox video connector - though perhaps a bit thicker

    Yeah, why buy an Apple product if you can't run windows? Might as well use Linux?

    WRONG! WRONG! WRONG!!!
    First cable is a monitor adapter cable for the first gen. and early second gen. Power PCs to use an older Apple Monitor.
    Second, that octopus of a cable is for the Apple IIe card used on the LC computers to connect Apple II disk drives and a joystick to it. That within itself makes it a very rare cable to have as many of them were thrown away. It is not for the Apple PC card as that card/cable connector is much larger.
    Third- the Price of the Mac/DOS machine was more than $4Grand at the time when you could get the Same Mac without the PC card for under $1.5Grand and a White Box 486 or Pentium PC for under $500.
    Fourth Apple only made the 486 version of the PC card with Applied Engineering making the Pentium version of the DOS Card. But as luck and fate would have it, within a year Connectix and other companies (and the shareware markets) started to make programs like SoftPC which emulated a PC running DOS and Windows 98 on a Mac without needing to add hardware and these cards became obsolete very quickly.
