This site is a comprehensive resource for a variety of upgrades to the Apple PowerMac 6100 and related machines. Contrary to popular press and opinion, the PowerMac 6100 is a very expandable and upgradeable machine! From its humble beginnings as a “beginner’s” Performa, my venerable PowerMac is now a G3-powered, multimedia authoring workhorse machine with all manner of options, input devices, peripherals and cross-platform capabilities. It took a little elbow grease and a lot of reading, but now that the leg work has been done, it’s really quite easy!
An extraordinary time capsule from 2000. These upgradeable Macs are some of the most interesting Macs Apple ever released, and I have a soft spot for the various rare and hard-to-find G3 and G4 processor upgrade cards – which is why Action Retro is one of my personal heroes.
I had one for a time, my first mac. I “bought” it from one of my friends as a favor because he needed some cash due to a family emergency, then I had to sell it back to him when he had the money. He absolutely loved the thing, as did I. Between the two of us we had it maximized, max ram, G3 upgrade card, Fastest Harddrive with max capacity, Upgraded to latest osx ( which it wasn’t supposed to even run). Got to play with powerpc assembly. So much fun.
I vaguely remember upgrading a PowerPC mac to a G3. If I had to guess i’d say it was a Powermac 9500 upgraded with a board from Newer.
I had a 6100/66. It was my first Mac. I got it used from a friend of a friend. It lasted me years. I updated it to MacOS 7.5.5 by downloading the floppy images from Apple and somehow getting the files on to the 6100, then 8.0 (my fist eBay purchase, before they had a UK specific site!!). It died because the battery exploded whilst in storage. Sad day I also have a bunch of 6100/60 that I got in a lot of PM’s when a local dealer was getting rid of all their old trade in stock. But they were all dumped in to eWaste as they were scored at an ex-employer and I had no where to move them to.
I used to pour over this site. It was like my Mecca. Glad to see it still exists!
