Was looking around ebay the other day and call apon a powerbook g3 wallstreet that was for sale. The seller said that the processer showed up a 450mhz g3 processer in the system profiler but didnt know anything about the units or macs for that matter. on the bottom of the case it was listed as a 300mhz/64/8. so im guessing it had one of the rare wallstreet processer upgrades that you hardly ever see. it could also have more ram and a bigger hd as well. i will report back when i get it
