The graphics arts program went belly up at my school so some really odd, rare mac and mac related stuff was, liberated. Besides the Mac Classic, Q800 and other stuff I found a Proxima Data Display. Its an LCD that fits over an overhead projector. It powers on (fan) but the video cable is a bit of a mystry to me. It has a 9 pin connection but I'm not hip on some typs of conntions. I want to be able to hook this up to a Mac, how can I? Any help?!"Holy crap! A Mac can do that!"-Every PC user I talk to 68K MLA: Black OPs Edited by - macaphile on 22 Jun 2002 16:32:21 |

Sounds like one of those old PC EGA or CGA connections to me? Not too sure about that, though.~Coxy - Leader, Tactical Operations Unit

That would be my impression also. If so, then I don't think you'll get it connected to a Mac. (EGA and CGA are digital interfaces vs. the analogue monitor interface (as is VGA) on a Mac.) Time to try looking up the model number on Google.

It's probably a RGB TTL type input, meaning it takes Red Green Blue and Syns signals - which *should* be the same pin config as a CGA/EGA connector. I reckon you could make an adaptor and it would work. Check out http://www.extron.com/technology/archive.asp?id=gcpinconfig for graphics card pin information.68k MLA ParaMedic |

VGA, CGA and EGA...in fact all RGB type video signals are analog. The signal on each line is 0 to 1 volt TTL (Transistor Transistor Logic):-) 68k MLA ParaMedic |

And then he reads the first line in the CGA/EGA video signal description.... goofball  Anyhow, i am assuming that the Proxima was desiged to be used with PC's, which would normally have a VGA output. So I am also assuming that there was probably a 15 to 9 pin adaptor in the kit... but you know what happens when you assume. It makes an ASS out of U and ME 68k MLA ParaMedic |

The fact that it has the 9 pin connector may be rare, but a panel like this isn't.~Coxy - Leader, Tactical Operations Unit

THIS JUST IN!
A NuBus video card with a 9 pin output has just landed in my lap! Ouch...
After removing the solder spikes from my stomach, I can clearly see the words MEGASCREEN 2001 © MEGAGRAPHICS 1988 and "This card for use with TTL monitors ONLY" on it. ~Coxy - Leader, Tactical Operations Unit
