"WallStreet" PowerBook G3 Series '98.
Purchased in spring of 1999.
Original specs: 300 MHz G3, 128 MB RAM, 14.1" screen, MacOS 8.1, 8 GB HD.
Final specs: 500 MHz G4, 512 MB RAM, dual 7200 RPM 60 GB HDs; MacOS 8.1, MacOS 8.6, MacOS 9.0.4, MacOS 9.2.2, MacOS X 10.2.8, MacOS X 10.3.8.
Shown here as used at my office with external Sony 20" monitor attached via VillageTronic PC card (in use as main screen), classic "Saratoga" ADB keyboard and Apple ADB Mouse II.
Was my everyday primary computer from spring '99 to spring '06, that's eight years as reigning Mac of the roost!
I now use it mostly for scanning from my elderly Umax Astra FS180 slide scanner (no OS X drivers) and my positively ancient
Umax UC-630 3-pass flatbed (no OS X drivers for that either). Although if I've got it hooked up for that I use it for browsing and other stuff and it still does everything I ask of a computer. (Too slow for the office LAN with that 10-base-T though).
