    Ok, I'm super confused. The battery that showed signs of life, the OS says it's now fully charged. I take the battery out and press the button and I see all 4 green LEDs light up. Now on the 5 copper pads on the battery, one is marked '+' and the one on the other side is marked '-'. Using a...

    Huh... left the lithium battery on the charger for a few hours and all of a sudden, it's got a bit of life. One bar. Going to leave it on for a bit longer and see if something happens.

    Yup, makes sense. Did similar when I coated the chassis in my 540c.

    The zinc coating is just for corrosion protection right? If so, putting a coat of rust preventative spray paint after removing the rust should be good enough right?

    Thanks! This will be helpful when I get to it. Waiting for the epoxy to dry on the new insert mounts for the hinges.

    It permanently removes the existing rust. But it won’t prevent new rust from forming.

    Yeah if it was plated, that’s it then.

    Working on the 3400c right now. I collected 3 of them in busted condition and it looks like I should be able to piece together one working one (minus the battery - struck out on all three). 2 of the 3 had missing PRAM batteries so someone saved them. The 3rd still had its PRAM battery but...

    If it's dark, my guess is there's still a layer of stuff (carbon?) on it. Polish is not going to be abrasive enough to take that material off - you'll probably be sitting there polishing for a really long time. Might want to get a light sand paper (800 grit) and try a small area and see if you...

    The 840AV on further testing wasn't working... it was failing to boot fully and sometimes wouldn't power on. I have since recapped the logic board, recapped the PSU, cleaned the logic board, removed the heatsink, cleaned off the old thermal paste, applied some new paste, put the heatsink back...

    I guess I could try :) Next stop is 40MHz as I have an 80MHz crystal around here somewhere. I guess we'll see.

    Radius Rocket Compatibility

    I had seen references in various threads on this board. Some I could quickly dig up: From this post: From this post: From this post: From this post: From lowendmac's review of the rocket: Seems like the PrecisionColor Pro series will get additional acceleration but I'm trying to...

    Unlike retrobrite, the super glue will take off logos printed on the cases. It's surprising how fast it works.. 30 seconds and the un-yellowed original plastic shows through. All the texture is still there so it's a light layer being removed by the glue. Not really applicable but interesting.

    If the area was already smooth, that's the end of the filling process, but if the area had some texture, I'll try (keyword here being try) to recreate the texture by knicking it with a rounded pointy object (tedious process). But note this filling only works because I usually paint the machines...

    I normally clean the area, fill it with JB Plastic Weld, let it fully cure/dry, and then use sandpaper (start with 120 grit, go to 240, then 400 <- I stop here as I don't want a gloss finish) to sand it to where it's completely even.

    I usually leave the little marks alone, treat it like patina. I just don't like orange level yellowing and cracks (for structural considerations) and big gashes, missing chunks, etc. The annoying ones are where large educational institutions carved their name/equipment # into the case, super...

    Within those 30 secs, the acidic part of the glue took off the yellowed top layer. Not sure if I've seen this mentioned before. Note I have had IPA brighten plastics as well, but that's after scrubbing for like 5-10 minutes and only sometimes. I actually tried scrubbing with IPA to the right of...

    I was supergluing a cracked corner of a case... the superglue was sitting on the case for about 30 secs when I wiped the excess glue off and noticed brightening. I made a test 'J' next to it, waited 30 secs, wiped it off... Hmm...

    Twiggy Mac Beep sound

    Both the dialog notification sound and the beep sound (when you clicked outside of the dialog) are cool. Actually like it better than the one they went with later. And nice Steve Jobs icon too!
