I just bought an old, late 2005 Mac Mini off ebay and having a helluva time trying to install Tiger on it. It did not come with any software. From my MacBook Pro, I put the mini in target mode and re-partitioned and formatted the hd with the option for PPC, so it would be sure to boot. I've tried booting from an .ISO cd with the "c" key held down to boot from the optical drive but so far all I get is the standard folder and ? staring me in the face. The model # is A1103. I'd also like to know, with all the install disc versions of Tiger out there, which is the correct one for this particular mini? Thanks.
