|
|
Guys
Just wondered if it went well. The required items appear to be:
a) Ultra top motherboard
b) Geom/Focus board
c) CLM firmware 4.2c or higher
d) DPB flywire jumper and firmware 5.5 or higher
e) 680 ohm resistors and flywires added to Convergence amp
f) Caps and resistors added to Vertical amp
Did I forget anything?

I've done it a few times. Worked fine. Iv'e got a 9500 sitting here right now with an Ultra motherboard, I just need a focus board to complete it...

As is the HDM, the CVA , Vdm and the DPB. The only thing that you really need that is specific
to an ultra is the FGM. I have always wanted to make a add on board for a stock FCM.

That should be quite simple task if someone with the know how produce a stack of add on boards, but no matter what im sure it will be more expensive than a complete ULTRA machine.
So seeing ULTRA machines go for free or close, and Craig selling a new FGM for 35$ i think its just for someone that dont have anything else to do, or like the challenge.

Guys
The Ultra was introduced so Ehome wouldn't need a standard Marquee, a Hi-scan Marquee and a Dome Marquee. The other choices were P43 and lenses, so it was easier to keep projectors on the shelf that met most requirements. Firmware 4.0 supports the added geometry functions, but I haven't seen a factory Ultra below 4.2c

I am just curious as to why this is actually needed. I mean....what extra stuff do you really get with the Ultra that you do not get right now? Do not call me ignorant, I just do not know if my image would be effected at all since the projector is almost near center of the screen with my ceiling being so low.

The Ultra has less banding tendency and some additional geometry functions such as V skew, and top/bottom keystone

Hey Tim,
Any idea why it has less banding tendency?

Well JB
Probably a better management of pulses and waveforms that control convergence, maybe Scott could elaborate.....

I am sorry but I thought the banding issues were stemming from the CLM board. If that is not upgraded than I am guessing the ultra boards are acting like some sort of signal or wavelength filter is what I get.

It is the way the original engineers wrote the scanning algorithm for the vertical deflection pulses/waveforms. The banding mod that the VDC engineer wrote is only on the Vertical wave forms. nothing is written in the add on chip for the Horizontal wave forms.
From what Scot told me to re work a new CLM at this stage in the game when that VDC engineer wrote the software for the add on chip would have been more money than VDC was willing to spend on a Phased out technology.

I agree with the option of not going forth with the chip.....but what ever happened to that mod? I remember seeing it one day and then gone the next.

Guys
I had two CLMs modded for that and both CLMs failed during testing, so I decided not to offer the mod for sale.

Two i have done seem to work fine. I had other things come up and have not tested thoroughly . I plan to do one of my Longbow CLM's that has the worse of the two banding issues. If I have no problems I might offer the mod but with no guarantees. I think there may be a compatibility issue with some later version softwares. The two I tried them on were pre 4.xx CLM software versions.
On those two, version 3.4, the mod seems to work with the ability to converge all zones. Geometry seemed to work well also.
I told Scott a month ago about the issues others have had and he said there should be none, his friend who wrote the program is currently using it on his Marquee with no issues at all.
So in a few months I'll know more.

The FGM has the added analog circuitry for geometry waveforms. The analog waveforms gradually make changes from one screen area to another. That minimizes any banding. The digital zone waveforms can make abrupt changes (especially in the vertical direction) from one zone to another and that causes banding.

Hey Scott,
Does the FGM minimize banding even when coupled with non-Ultra boards or does it need to be a full Ultra set to utilize the benefit?
Regards,
Justin

Well, the firmware has to support the DACs that are on the convergence section of the FGM and maybe some wire jumpers to get the convergence signals to the convergence amps. But yes, a non-Ultra set can be modified to make use of the FGM.
