Picked up a Sonnet Crescendo G3 500MHZ upgrade card tonight on the cheap and was going to put it in my Power Macintosh 9600. Problem is I'm not sure if it will be worth installing the upgrade. The plan was to upgrade to Tiger but with such an old machine will it even function well. Any suggestions
About 9 yrs ago,
I saw a PM9600 with a G3 900MHz upgrade (OWC) and
a Radeon 32MB PCI Vid Card.
RAM wasn't full, but a decent amount existed to try an attempt with OSX
(can't remember the exact RAM amount).
xPostFacto got Panther installed & running.
...the glee the owner had back then for such an accomplishment

YouTube ran a bit choppy in a small window
(Jake from Hawaii playing his ukelele, "While My Guitar Gently Weeps").
But now, thinking of this OSX performance chugging through a 50MHz system bus...
Personally, I'd think the 9600 with all its PCI slots would make a great old Mac OS Classic machine
for running all those old Audio/Visual software/hardware packages that one reads about in the past.
But then that means looking for those old sw/hw packages (for cheap only) on eBay & craigslist.
But for a collector/tinkerer, that's kinda cool.
I'd definitely install that G3 500 upgrade for whatever purpose.
