Well, both the CRTs have bad color convergence. Not to mention a misaligned raster. Probably from the disassembly process.
Oh how I don't miss CRTs. Little 9-inch displays I can handle. These are a whole different monster.
So, this story picks up from where we left off. This bugged me somewhat, and I had no idea how bad it was until I removed the CRT again.
I decided to switch back to the original bezel, which had some cracking but was otherwise quite structurally sound.
Some hot glue was injected into the gaps of the front bezel to reinforce it in some of the weaker spots. Now this stuff can soften with heat, but it takes a decent amount of heat to make this stuff melt away. I had to wait until my gun exceeded well over 100C before I could even begin to extrude it. If the glue on the Analog Board can handle it, this will be able to.
You can see a slight amount of red, ever so tiny, around this corner which tells me the convergence is out slightly. Not worth worrying about. What is worth worrying about is how badly the raster is aligned, which I've corrected in software for the time being as I couldn't be stuffed messing with the CRT rings.
My verdict so far? I don't really like these iMacs now. You can learn a lot about a computer by diving deep into its innards, and the iMac is about as bad as it gets for build quality. The ABS-FR plastic of the inner bezel wasn't built to withstand any kind of long term heat, and therefore it makes a poor platform for any kind of project, which is a shame as they look quite nice. Of course this does not apply to Tray Loader iMacs, they tend to be much more structurally sound and - if you ask me - better designed overall.
The second iMac, the one I acquired at the start of this thread, turned out to be in even worse shape than I initially envisioned. Someone had clearly had it open before, forced some of the plastics with a screwdriver as they're chipped around the seams, and forgotten to reinstall a ton of structural screws. It's perhaps only good for its case plastics, if that.
The solution? Perhaps swap the plastics onto another iMac. The drawback to this? I can't guarantee that iMac will be any better either. Not to mention that i'd then have a total of 4 iMac G3s in this room and I'm sick and tired of them as-is.
I think, for an OS 9 machine, i'll turn my focus back to my PowerBook G3 Pismo.
