It was a sad day when CRT manufactures closed their doors. Right when lots of new advancements were happening. Glad to see you guys hanging in there. Post some screen shots when you get a chance.

I spoke to TSE from VDC about this years ago. He said CRT didn't have any more secrets to uncover. It was a mature technology that had been vetted pretty good.

Mature technology, yes.  Optimized for HD BD, no.

Adapting the technology for optimal consumer use with HD BD is not what Scott was ever involved with.  God only knows what he could have done had he been given the time and resources to optimize the Marquee for such a venture.  A stock Marquee vs the latest modified examples is really no comparison when evaluating top tier image fidelity.  Unfortunately, there's only a handful of people who have seen such performance from a CRT.

There has been just around 0 development in CRT tech the last 20 years.
It is not impossible to make huge improvements to CRT if it was optimized to todays movie standards, like the right color filtering, 16:9 tubes, or maybe even better, a anamorph lens compressing a 4:3 to 16:9 adding a lot of light output.
Further develope tubes to add resolution, light output, and longer life span.
Optimize the videochain for todays bandwidth, and there is a loooot of noise issues in CRT projectors that would be pretty easy to deal with today... Who knows, might even be possible to replace the electron gun with a laser, and just shoot on a phosfor coated glass plate, saving a lot of space and magnetics.

Even with no development and no manufacture support, i think its quite amasing how it has been possible to push HD performance on CRT to a point where its hard to match with any of todays tech.

It depends on how you define development. Scott modified Marquees and Ampros for customer needs.

I agree that Scott probably could have done some interesting things with a Marquee to adapt it to HD. I am not sure how much, as he said almost all IC manufacturing and development stopped like 15 years ago. As I am sure I have told both of you that he spent the last five or six years of the '00s trying to maintain the pedigree of the Marquee with what was available. Kind of like a CRT version of the Apollo 13 team.

I know Scott is kind of a Marquee hero to some.. I can see what he has done to the Marquee over time.. From a image fedility standpoint the Marquee peaked in around 1996, and slowly degradet after that, with some major hits in 2004 and 2008, to the point where the last 2010-2011 produced Marquee projectors is pretty much useless for video presentation.
I know that some components went obsolete, but that dont give a good excuse for some of the extreme poor replacement designs.
I have listened to a planetarium tecnician explain how it was to run and maintaining 6 late build Marquee projectors, and what he was able to tell me was that it was extremely non linear behaving and they had to settel with a very very low light output to calibrate it to a decent gamma performance.

So no thanks to Scott from here for the way he was involved in degrading the image quality of the Marquee.. Ill expect he have been under some financial preasure to do something as cheap as possible, or he would have taken advantage of late build ICs that is performing much better than the used ones, but it would have called for a new VIM design, and a retake of the 2008 neckboards, i doubt he was given the funds to do something like that.

For sure, the new VNB design was because they no longer produced the Motorola transistors and you can bet with more time/money the result could have been better.  I rembering conversing with Scott and him telling me how much he'd have enjoyed working on a consumer home theater solution but as we know VDC's market is for industrial use so no dice.

To your other point; 16:9 tubes with a laser based phosphor system and modern electronics would produce an utterly amazing result.  Just need to find someone with seed money
