I recently got a Apple Power Macintosh 6100 for free. It powers up and seems to work, so I want to try it out and see what it's like. Unfortunately, the important ports and connectors are "non-standard", which means I can't directly hook up the things I have:

I'd like to connect a standard monitor (With VGA, S-Video, or something else which have), as well as a keyboard and mouse (I have some PS/2 keyboards an mice lying around). There seem to be adapters for HDI-45 to VGA, but I want to do this without buying any additional parts (i.e. free). I'm comfortable with soldering and making things, as well as electronics in general.

Is there a way to connect a more "Standard" display, keyboard, and mouse to this computer ?, and, if so, how do I do this ?

Is there anything else I should be aware of ?
