Default Old projector parallel port labeled as VGA connector?


The image above is crucial to understanding this, here's another link if you can't see it:

I recently bought an old projector "Magniview Multi-Media Projection System". It's supposed to take the computer's output and project in a 640x480 resolution.

Well, the problem is I don't know how the heck to connect to it! I have a VGA and DisplayPort output on my laptop, but I can't find anything like a VGA to the parallel port that's on there connector (maybe that's a stupid idea?).

An alternative may be a VGA to S-video converter box, but that's expensive and I would like to get this strange choice of parallel port working.

Does anyone know how to communicate with this old technology via VGA?
Thanks.

The parallel port isn't the video input, there are 3 video inputs, 1 S-video and 2 RCA jacks. You need something like this to convert the VGA signal: PC-To-TV-Video-Converter

Actually I highly suspect it is an old component analog video input. DB25F connectors aren't just used for parallel ports.
But since I can't find a cable or even a diagram of RGB in/out/refresh to make my own VGA connector for it, I'll probably end up settling with a converter box.

There is also a DVI port (the white port) all you need is a $3 DVI to VGA converter

That's not correct, Banto. It does not have VGA or DVI ports.

I bought the converter box for VGA->Svideo. I guess that DB-25f port will just have to remain a mystery.

DB-25F is a form of SCSI. There adapters out there, but only from male to female or to different DB families.
