I have Jaguar running on it. It has to be installed on to the first 8 Gig I think. I have it on a 20 gig drive. I partioned so that I have a OSx partition, OS9 partition, a swap partition and one 10 gig parition I call free. I use free between OS9 and X. I am still using OS9 because I can not capture video fast enough throught X.
One Major problem I had was I had upgraded my memory to 512 Meg. When I installed 10.1.2 I did not have any problems. When I installed Jaguar half way through the install the screen faded to blank. It turns out that the Jaguar installer does like seeing the extra memory. If you look at the specs for a wallstreet the max memory is less than 512. That is because the chips were not avail at the time. To fix the problem I took out one 256 Meg chip. I then installed Jaguar with out a problem. I installed the chip afterwards and Jaguar recognized it without a problem. Apple by the way was no help on this. They told me the memory or the hardrive I upgraded too was probably not Apple spec. Make sure you make the Jaguar parition large enough. I didn't and haven't been to install the softare upadtes to it. It was very frustrating until someone of this board clued me in.
Jaguar recognizez everything but my floppy drive. It recognizes by firewire2go card and my zip drive without loading drivers. Neithere worked in 10.1.5. I have never used a printer with my wallstreet so I can not tell you how that works.
Do a custom install unless you want all the languages installed on your machine.
