I love this forum!! looks like the IC 421 might be getting a permanent fix it from the smartest guys on the fourm!!!

Craig i wasn't expecting you to divulge the exact info, but the info you gave in the post was all i needed. I was just curious if Roges advice was part of it.

No worries, I just didn't want anyone to think that I'm out of G90 stuff completely. You're just better at the Ya boards than I am, and I've got no problems admitting that, esp. when it comes to keeping CRT alive and well. I do have stock of most other Pc boards for the G90, save for a working Ya board to sell.

"There’s not much to talk about, the solution is straight forward consisting of a PIC processor, a gate array, and a interface board. Basically, the PIC and gate array emulate the IC421 functionality. The PIC is needed to decode the commands from the YA cpu and format the data strings for the DAC’s. The gate array is required to accommodate the high serial data transfer rate to the DAC’s. Of course, the key is to understand the logic in the IC421 chip then programing it into the PIC. "

I could swear that this was alredy suggested in this thread or another and that idea was cast aside. Who was that masked man. Probably some whacked out AmPro doofus. Rolling Eyes

Just wanted to report that my YA board was repaired by Craig and all has been well since then.

Thanks!

I also have been wanting to post that Craig has fixed my YA board about 4 weeks ago and it has been working perfectly. My wife had surgery around the time the board arrived and I have been extremely busy taking care of her and our business. Craig, Thank you for the great job!

After almost 8 months my G90 was down and watching a Viewsonic Pro8100 LCD projector to hold us over for viewing I forgot and appreciate the G90's great picture . It is so smooth, filmlike, noise free and natural.
The Viewsonic - $1200 -1080P - for the money is a decent projector for TV and sports but just dosen't compare to the CRT for film based material.
