Pismo (powerbook g3 with firewire) upgrade to mac osx 10.4.9

Question

After having this Powerbook G3 Pismo (400 MHz, 2 firewire and 2 USB ports) I decided to upgrade from 10.3 up to 10.4.9 (if doable).
Since this Powerbook G3 had a 5.59 GB hard drive (which had 12% free space) and 512MB RAM I could tell there were many things that had to be done but I'd try them in steps first.
I ordered additional RAM (2 512MB cards from www.powerbookmedic.com) for $189.90 ($94.95 each 512MB card). The idea would be replacing the two 256MB cards. The cards arrived 3 days later and I had no trouble replacing the top 256MB card (thus going from 512MB to 768MB) but the lower card was going to be a bit of trouble.
I noticed a performance change right away with activity monitor (CPU usage, system memory, etc) and decided it would be worth it to continue.
Circuit City in Deerfield Beach, Florida is an authorized Apple service center so a trip to them was next. I explained that I wanted the hard drive replaced (5.56 GB) with a 60 GB one ($80 for the hard drive), and install the 512MB card that I brought with me ($30 labor). Paid for all of items ($80 for hard drive plus $30 for labor) and went home.
A few hours later Circuit City called up and said I could pick up the Powerbook on Sunday morning after 11:00. Wow!
Picked it up and tested a few items by doing a software update (it now had 10.3 loaded on to the 60 GB drive). I used Circuit City's wireless connection there at the service counter. All the updates came up fine (glad they did not charge me for bandwidth).
Off to home and where I still had my Mac OS X 10.4 DVD from my MacBoook Pro 17". Put in the Mac OS X 10.4 DVD and kept my fingers crossed. It worked, took about 45 minutes all said and down.
Under system preferences made sure that synching thru .Mac was enabled so now my Powerbook G3 has all the addressbook, bookmarks, iCal, etc of my Macbook Pro.
Not a lot of dollars ($300) to get a 7 year old computer (February 2000 when purchased) to year 2007.
Can't say it would work the same if I had a lombard or wallstreet version but it certainly did work out well for pismo (400 MHz, 2 firewire and 2 usb ports). It makes me think how advanced this powerbook g3 was back in early 2000.

I'm very surprised that you were able to use a Model Specific install disc, for an Intel Mac, to install a functioning system on a PPC Mac.
