the stealth imac + stealth for the pci graphics b+W/yikes are all interchangable i believeĪnd use the same connector, fit inside the same form factor/sizeĪgain i may be wrong, but i believe they literally just folded the connection orientation in half. In the silver/metal box there was an orange/brown ribbon-type connector that went from the motherboard modem connection up to the silver/metal box that contained the g3 modemĪlso here you see the connection, in its wider single lane orienteation:Ĭlearly visible in this image. I have taken photos of the connector i just have to find the photosĪnyway u can see the connector type if u know anyone that has a b+w g3 that had a modem installed Literally folding the connection double over and in half so that its two lanes + shorterīut its the same pins but in a long/wider orientation i believe

I believe its the exact same layout as the g4 except they changed hte orientation by I can provide you with information re: the pci graphics g3/g4 connector They too, like this device, access the serial port by otherwise unmarked lines on the modem port. However, these are no longer manufactured, and the eBay availability (and prices!) are sometimes a bit ridiculous.

There were a number of products that solved this dilemma in the same fashion. Jamport allows you to access this hidden serial port and use it on your Mac, as long as you're willing to replace the modem card with it. However, most Apple hardware until the PowerMac G5, still (internally) supported the serial port! It was just tucked away on an internal connector! However, if you wanted to use some older device that used the serial port, you were fresh out of luck.

This was fine if you'd purchased some newer hardware that supported USB, or Firewire. Starting with the PowerMac G3, Apple began removing the old serial port/GeoPort connectors on their product lines, and replacing them with USB.
