Impulse Firecracker 24 help

[HammerD]

The ROMs on the card are in the right place? (just to be sure). Any socketed chips you could push?

At least the white screen is a stable valid signal, as reported by the monitor?

There are only 2 socketed chips, I did press them in and they creaked   Didn't help.  There is one jumper on the board, I will move that to see if it helps.  I'll do some more tinkering with it later today...including trying it in my Amiga 4000.

Tried the Firecracker in the Amiga 4000.  Same result - white screen when rendering an image to the board.  I give up   Switching the single jumper on the board had no effect either.

Ok, I think I may have found the issue. I removed the board to inspect is closer and found one of the IC's is cracked. It looks like something heavy fell on the board and cracked the IC. It's also pushed sideways (as is the adjacent IC). I've ordered a replacement chip so hopefully that will resolve it!

Welcome back HammerD and hopefully that resolves the issue. It's been a Firecracker of a time.

Thanks I hope so.  I've ordered a replacement chip and I'm thinking about how to replace it.  I don't have lots of expertise with soldering (nor steady hands).  Sending it off to someone for repair in the current environment would take alot of time (and money).  Maybe half of what it would cost to buy a 2nd hand OpalVision card, for example.  So we will see!

Y'all are making me want to pull out my Firecraker card and try it out. Last time I used it has to be over a decade ago. I know it worked on an 040 setup. It was wicked cool to use with Imagine that's for sure. If I rustle up the energy I'll try to find the card and install it and take it for a spin and report back.

It would be nice if you can test it.  From what I could tell ImageFX would work very nicely with it, and also Viewtek would work.  My card partially works, ImageFX can turn on and off the card, but when it goes to show the image (after turning the Firecracker display on), it just displays a white screen.  It does turn it off (black screen) successfully, and ShowConfig sees the card.  So I'm hoping that cracked chip is the problem.

Well I got my card back from repair and....it works! However, if I choose a higher resolution to render the image (in ImageFX) the image appears "washed out".  I'm not sure why.  Also larger images either don't load (perhaps too big?) or are washed out.  smaller images do work, however, at the lower and mid resolutions.  At 768 x 482 or 1024 x 482 the jpegs are washed  out.  Not sure if that's a software issue (I only tried under OS 3.9 with an 060) or not.  I will try under OS 3.1 and see if it makes any difference.  But at least it works, mostly!
