card guide...

Something like the attached image perhaps?

It would have to have a piece perpendicular to the guide with space for two screws to fasten it to the motherboard. Unlike PC card guides these don't fasten to the case but rather to the motherboard.

Tom, could you point me to a picture or a drawing of what the correct part looks like? The image I included was just a ballpark guess as to what you guys would be after. It's been 25 years since I actually looked at the insides of an S-100 box in person. :)

Here are a couple of pictures of what the card guide looks like.

Thanks Mardy!

Can you tell me how wide and deep the slot is, how high the "tower" is and how wide the foot is? I also need to know the hole spacing on the bottom.

I can make something that will do the job but it will NOT look just like that. It would however be mechanically identical.

I'm in the process of creating a 3-D mechanical drawing of the original card guide. When it is completed, I will post the DXF file.

Anybody out there have the resources to make a mold?

Yep. :)

I was hoping to trade a kit for my services as I don't have the money for a kit, but I _really_ want one. :)

Here is a replica design that I put together. The DXF and IGES files for the design can be found at the following URL:

That looks really nice Mardy. Unfortunately it doesn't render at all when I import it into Inventor 10.

Can you try saving it as a DWG file? Any version of AutoCAD from 2004 and prior I can read in Inventor.

tnx!

Thats nice. Did you use Cobalt?

Since you did the drawing, I wonder how cheap the tooling would be... :) The price I got was if they had to reverse engineer my part.

[mardy]

Unfortunately I think that machining the mold is still the hard part. But then, having never done one before, I could be wrong.

I drew this with a simple Mac CAD package called TurboCAD. They also make Windows versions. It's very inexpensive. After the $40.00 mail-in rebate, it cost me $60.00. It's not SolidWorks, but it also costs a fraction of the price.

Gene, I re-exported the DXF file so that it is now AutoCad 2004 format. Hopefully you can import either that or the IGES version.

Marty, no go on either one. :( The IGES version comes in really weird to Inventor and when I load the dxf into AutoCAD all it shows is a single circle. It's kind of strange.

[mardy]

My bad. I generated the IGES file in 2D instead of 3D. I verified the updated file with another CAD program and it seems to work now. As for the DXF file, there is definitely a problem with my CAD program and DXF exports. Give the IGES file another try and let me know how it goes.

Still no joy Mardy, sorry.

If you could give me a dimensioned drawing set, I could rebuild the model in Inventor.


Grant, have you read your PM yet?
