I forgot to post here. Here's a video of me disassembling a working iMac G3 DV and fitting in the boards to turn it into a monitor. At the end I play Minecraft with it as the monitor. BTW this is a non destructive mod and it can be easily reversed.

If you can solder then you can assemble this, it's actually not too bad. I purposely used through hole components so the only piece of equipment you would need is a soldering iron. That said, if you don't have any experience with electronics then I can see why this would look daunting. I'm...

Nah, just like to tinker but thanks. I just bought a Pi 4 for this project and I hope to have it running with my G3 this week! So far I have no plans to change the J20 board or the down-converter break-out board but I might make a change to the J22 board to make it a little easier to connect...

I did and built them and they work. I have instructions on how to order them in the repo. I ordered 5 of each board so I have 4 of each left over. I did make a change to the j22 board but I haven't ordered an updated one yet in case I make more additions. Here is the link...

If anyone is interested or has more info in the way of sniffed comms between the iMac G3 DV logic board and the IVAD board please share. With lots of help, Ive gathered enough info to make three printed circuit boards to convert the iMac G3 DV into a CRT monitor which can be used by a regular...

Here is a link to one of the videos

I'v been scouring the internet for documentation on pinouts for the iMac G3 DV so that I could make breakout boards that plug into the chassis connectors. This way one could 'hook" into the CRT in a nice way. I have collected and organized some pinouts and made my own diagrams based on my own...

Hey all , I've been unavailable to work on hobbies for a number of years but I now have some time again for a bit and I was hoping to work on an iMac. I was wondering if anyone has done this same hack but with a iMac slot loading G3. I've made good progress with help from people over at...

Thanks, just having fun!

I think with a little work everything can be done with one arduino using the same i2c lines. I'll have to sit down and merge the master and slave code so that the CRT is turned on and then the edid info is provided all in the same sketch. I'll let you know when I get it working.

Hi, Patricio What I'll do is grab the existing sketch and pull the external circuit stuff out of the code. I can't test it as I can't open up the eMac until next week or so. Here is the link with the changes so that the arduino will send the init 5 seconds after being powered up. I also kept...

Just uploaded an arduino sketch that simulates the eMac CRT. https://github.com/qbancoffee/edid_simulator Also added a video Here is a pic of how it's wired.

looking very nice! Can't wait to see how it turns out.

By the way the extension for the ivad init code sketch is wrong https://github.com/qbancoffee/emac_ivad_board_init the extension for the sketch should be ino instead of io and it should be placed in a folder named the same as the filename. I'll get that fixed one day.....

o.k. For whatever reason when I posted the code on this forum, after it was analyzed, the brackets were removed. there are supposed to be brackets after the array with the index variable "i" "edid [ i ]" <code>edid</code> I really haven't had time to test this code but I had mixed results...

you are the genius that started this!

I think this is a good starting point. well have to iron out the details

only if it works! thanks!
