| DOS Compatibility Card for Power Macintosh 6100 | |
| Posted by: SteveHere on 2020-10-29 18:59:11 I've got a new to me Power Macintosh 6100 that came with the DOS Compatibility card (Houdini II), but no cables for attaching it. I've already started designing an adapter board to replace the difficult to find and expensive Apple Part Number 590-2014 splitter cable based on the pinout online here. Before I go to the trouble, I thought I'd ask the good people here on 68kMLA if there's anything out there for the DOS Compatibility card like this? Has this already been done? Would having this design help anyone else? | |
| Posted by: Byrd on 2020-10-30 05:12:51 Hi Steve, nothing that I've ever heard of - you'd be the first. DOS compatibility cards were somewhat derided over the years as they were never as good as pure x86 hardware but now they're becoming popular. | |
Posted by: bigD on 2020-10-30 11:55:47Has this already been done? Would having this design help anyone else? I have a Houdini II that I've always wanted to get running in my Quadra 700, but misplaced the cable during a move. I'd love to have a replacement - if you build some adapters I'd be happy to buy one from you. | |
| Posted by: LaPorta on 2020-10-30 12:10:33 The huge win for me would be if someone, someday, somehow, made a simplified adapter to allow connection of the DOS Card in a 6100 to connect directly to that absurd connector on the AudioVision 14" monitor instead of requiring TWO adapters! | |
| Posted by: BadGoldEagle on 2020-10-31 06:01:27 Once I'm 100% done with the QuadrATX, I'll start working on an adapter for the Q900/950 with MIDI out. | |
| Posted by: arnold.exe on 2020-11-24 19:34:35 I ended up with one of these cards and would be down for one of these adapters, as mine came without the cable. | |
| Posted by: SteveHere on 2022-04-23 13:52:43 After a long hiatus on this project, I have started in on it again. I've got the first spin of boards back, and the board partially works, but not completely. If I plug the monitor into the "Monitor Out" connector, I get video from the DOS card, but the "Pass Through" connector does not work, so as it sits, I could use this with a dual monitor configuration but not as intended to switch back and forth with a single monitor, which is something I'd really like to be able to do and offer to everyone (like the Apple IIe Card Splitter Cable) My design is based on the pinout shown here... Has anyone on the forum built a cable using this pinout? I'd like to confirm that this is correct, but I don't have a cable to test / verify function with. | |
| Posted by: Unknown_K on 2022-04-23 14:00:55 I wonder if you can just run that card stand alone with a simple cable that has audio, video, and joystick connections with its own monitor. | |
| Posted by: jeremywork on 2022-04-23 14:10:05 I was refreshing my memory last night on this site, which refers to building the cable, and modifying/appending it for MIDI support, which was omitted from the factory: Power Mac 6100/66 DOS Compatible – MIDI « modelrail.otenkoOn the page they refer to the popcorn.cx page you already posted, in addition to these two: | |
