So 400mW won't be a problem, there?

Any other source for those resistors? Unfortunately, it appears only bulk orders of 100, at $10 each would mean I'd spend $990 dollars to have 99 spares. I'm just looking for a like-for-like replacement, and mine is similarly burnt up.

Still no luck getting it to get past booting. I swapped a SIMM from the main board to see if it would change the behavior. Other than making the Mac OS side of things not boot with all extensions on, the behavior was the same. No video out. I also tried hooking the video out to two different...

OK, I got System 7.5.3 and 8.1 installed on a bluescsi and installed PC compatibility 1.6.4 on each. I created a new DOS disk image file and mapped it to the C drive. So I believe the PC Setup app can tell there's a DOS compatibility card in the computer. The problem is when I switch to the...

Nice. Thanks for the information. I definitely noted the connections to the CDROM and main logic board when disconnecting the two small ribbon cables. I was able to get it reconnected this morning. I ended up hooking up the machine (with it's octopus connector) to a known good VGA monitor...

I can definitely see the problem with the space. That setup you have essentially looks like it takes hot air from the PPC heatsink and blows it onto the 486 heatsink, and then it bounces off the board and gets moved across the PPC heatsink.

I picked up a boxed 6115 a while back and didn’t do anything with it when I first got it other than to open it up and remove the battery, then try to power it up. Unfortunately, I got no video out on the multisync 15” monitor that came with it. So I set it aside, having other more pressing...

I think you got your answer. It's going to be nearly impossible to tell without removing the board. There are a lot of obscure 3rd party accelerators out there. You might get lucky and find someone who has the same board and would recognize the underside of the board without any markings, but...

Some of my items have the original boxes, in various states, that I'd like to store, but don't want them to be destroyed. I like to use my vintage Macs, so the items are not stored in the boxes, but I also need to make room in my bonus room for actual living, and was going to move the boxes to...

From my understanding, this mod will work with the Takky mod, although I wonder if the additional strain on the analog board from the VGA mod, combined with the additional power needs for the PowerPC chip will shorten the life of the analog board. Also, with the Takky mod, you're already...

You can reach the iMac G3 battery through the opening meant for installing RAM or Airport Cards. It's not super easy, but not too hard to get it out.

Appreciate the reminder. I was looking at my collection and couldn’t remember if I had taken the battery out of my TAM. I get kind of lazy with my PowerMacs because they have the 4.5v box batteries that I’ve seen fewer horror stories from. Popped open the back and sure enough, I still had the...

I'm not sure. I bet @Kay K.M.Mods would know, though.

Any idea if you can get a new edge connector for the Color Classic / Performa 575 logic board? I got aboard from a non-working Color Classic only to find it was due to a broken pin, I was able to solder a little bit of metal to replace it. And the machine worked, but it looks terrible and I'm...

(Edit: adding disclaimer: I should make it clear this is not due to lack of information on JDW's video. He covered it at 7:15 of the video, but I'm an idiot and even though I watched the whole video when it first came out, I skipped ahead to the action when I went to go watch the steps today...

It's likely an issue with my printer. My supports didn't come off cleanly and there was some left over supports on the bottom which pushed the board up as a slight angle. and there may have been some left over supports on the bottom edge of the top of the opening. So the card was rubbing...

Really love this design. Is there a reason you didn't make the opening a bit larger for the microSD card? Maybe my printer is printing a bit small. but I need to use pliers to get the SD car because it's so tight of a fit. I like the look, but it feels like the SD card opening could be twice...

If anyone runs into this, I may have some suggestions that could help. I ended up removing the CRT, then disconnecting the plastic frame that holds the analog and logic boards from the front face of the case by depressing the two tabs on each side where it joins to the front of the case...

Anyone else have extreme difficulty removing the Color Classic analog board after all cables have been removed. I watched @Branchus' video on the removal and his slides right out. Is it possible the edge connectors are fused somehow. I've used a good amount of force and cannot get it to...
