Author Topic: General Electric P9000 Jonathan Worthing Master Film Handler Posts: 384 From: Hereford, UK Registered: Apr 2001 posted 02-04-2004 08:16 AM                     Has anyone seen a General Electric P9000 projector. A guy rang me & asked if we had a manual for one. He had picked it up from a privet collector. I asked him if it was 35 or 70 mm, but he did not know as he had not seen a projector before ( You can see where this conversation was going.) After asking him a few questions he told me that there was a lead coming from it which had VGA stamped on it. It was in a flight case 1 M x 1.5 M x 80 cm Sounds like a old monster to me but who knows  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-04-2004 06:30 PM                     I believe the P9000 is a GE Talaria light valve projector. These are touchy beasts to say the least but are capable of large, bright projected images with awful colorimetry assuming it is a color model...there were B&W versions too capsble of very high resolution. It would certainly be nice to know that one has survived for a museum piece! The forunner to the GE was the Ediphor which was one of the most amazing video projectors ever devised. Both had similar workings except the color GE's did color decoding/scanning an entirely different way than Ediphor.

Dr. William Glenn was one of the key inventors. General Electric is gone now, and Lockheed Martin does defense work at the plant. I seem to recall the demo had tiny "bubbles" occasionally floating through the image. Here's a tutorial "white paper" on electronic projection technology by Texas Instruments: http://www-en.enseeiht.fr/enseigne/tsi/tvnum/display/titj03.pdf  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-10-2004 07:58 PM                     John, The employes that ran the G.E. Talaria division bought it from G.E. and ran it for some time but I don't know if it is still in operation or not. The bubbles were in the oil film that circulated over the target that the electron beam scanned...similar but not exactly like the Ediphor Projector. Mark  |  IP: Logged
