VGA-to-RGB

One of larger clients has a piece-of-junk ancient Proxima projector
that requires RGB input.

My laptop can only output VGA flavors and NTSC.

I believe there's a simple cabling adapter to convert VGA to RGB.

But the Proxima doesn't use RCA inputs, it's got some bastard
connector somewhat like VGA but longer.

Anyone know how to attack this?

(I should have gotten the model number when I was in Colorado but I
didn't :-(

The last Proxima projector I saw had a custom connector
which combined the 15-pin traditional computer video
(RGBHV, VGA, whatever you want to call it) with a USB
cable (for the remote-control function) Takes a custom
cable that has the traditional 15-pin connector and a USB
connector at the other end. Cable was likely included with
the projector.

This customer never uses the projector? Or never uses it
with computer input? Did they loose the cable?

Call and get the model number, and all the cable info should
be here... http://www.proxima.com/tools/cables.asp

As them if they use a VCR with it. If they do, then hopefully either
the VCR will have a compatible NTSC input (composite? S-Video?) or you
can take one along that does and use their lead. Pick the right
channel on the VCR and you're done.

OK for vacation photos, but trying to squeeze detailed technical
info through composite (or even Y/C) NTSC video may not cut it.

It was described as a "piece of junk" projector :) That made me think
it might be more like a pub/bar TV projector than the kind of thing
anyone in their right mind would use for a presentation. Anyway, from
your post it seems it's likely it can take VGA which will, as you say,
be vastly superior to NTSC.

I have a PC which serves mostly as a PVR so its only "monitor" is a
TV. It's truly awful for anything but watching TV. Thank god for
remote administration!

They're using it with ThinkPads. I have a 5 year old Vaio.

Thanks! Good link.

I use a ThinkPad at work and a Viao at home. They both use
industry-standard 15-pin, "A-shell", D-connectors.
