i have an ADAT+lightpipe on the way.. i'd be happy to do some preserving.

Swami, I can get that light pipe mailed tomorrow. I have a couple packages going to post.

And BJ, you can lightpipr right out a ADAT to your HD24 to archive them digitally. If you need a cable say so and i'll send extras with swamis card. If I don;t have them here I have a pile to be tossed out at work.

Unless they have to be processed through that modem, then you will need to record them ILDA out analog and the HD24 can't do that. So you will need to go back into a modded ADAT. Then dub the new master tape out lightpipe to your HD24.

Sounds good. Yes, I need the cable. Help step me through the process? Perhaps I can talk swami into coming over here. I may perhaps, try scooby snacks also. On another note, I am OFF TO SEE THE WIZARD, the wonderful wizard of, um, er professor Ron of Cave Creek to revive the Starscape xenon lamps for the Death Star (4 foot diameter starball that came out of Kansas City, MO Science Center. Ron can breathe life into anything that is planetarium-related. I am blessed to have so many friends that care about the same thing I do. Thanks to you ALL !

Are those Cermax lamps in the picture?
Those Look like old ILC power supplies.
Before they were bought by Perkin Elmer.

Yes, these are Cermax type xenon short-arc lamps. I heard that they can explode so I try to be careful with them. One common application for these are in endoscopy where the light goes where the sun don't shine. Personally I much prefer this application for making stars. The light comes out in a sharply-focused cone and I would avoid looking directly into them when they are illuminated. They are mounted in a heat sink with thermal grease and are fan-cooled. The ILC supplies came with the star projector and were mounted down in the pit. I still see these ILC units on eBay occasionally although almost always overpriced at around 1,000 which is ludicrous. I found a modern supplier Carsan Engineering out of Colorado that manufactures modern solid-state xenon power supplies / triggers that are a fraction of this size and fit in the palm of my hand. I bought one last year, they are still expensive though at 800 USD so I try to stick with the old stuff whenever possible. Today's project is to put some of these machines on casters so I can assemble them.
