Released alongside the 233mHz Wallstreet, the PowerBook G3/250 (Wallstreet), formally a member of the “PowerBook G3 Series” as dubbed by Apple, but more commonly referred to by its codename of “Wallstreet” , features a 250 MHz PowerPC 740 (G3) processor but lacked any Backside Cache.  This led to it being dubbed “Dog slow” or Mainstreet becuase the lack of a backside cache slowed the computer considerably.


The Powerbook G3 250mHz was equipped with a 2.0 GB or 4.0GB IDE/ ATA2 hard drive that could be user upgraded to 128GB maximum.  Partitions larger than 128 gigabytes were not seen by the Powerbook.  The Laptop also incorporated a 20X tray-loading CD-ROM drive in the hot swap bay.

Expansion Bays:

The Wallstreet models all incorporated dual “hot-swappable” bays which both can hold batteries or expansion modules (the left is a 3.5″ bay and the right a 5.25″ bay), dual Card Bus compatible PC card slots, and a new “fn” key which creates a numerical keyboard for quicker data entry. The 13.3-inch and 14.1-inch models have S-video out as well.

Custom Configurations:

The Wallstreet “PowerBook G3 Series” additionally was the first PowerBook line available “buld to order”, and as a result, there were many possible configurations of the PowerBook G3/250 (Wallstreet).

M6357LL/A had a 13.3-inch display, 4 GB of SGRAM for video, and a 4.0 GB hard drive for US$3899. It originally cost US$2979 when configured with a 12.1-inch display and US$4399 when configured with a 14.1-inch display. Other configurations were available as well.


The Wallstreet Powerbook takes 144 pin PC100 SODIMMS and shipped with 32MB RAM installed as standard.  Apple officially supports 192 MB of RAM in this model. However, third-parties have been able to upgrade it to 512 MB using two 256 MB memory modules. The Wallstreet models all accept PC133 SODIMMS (CL2) as well as these are backward compatible with slower bus speeds.


Supplied with an ATI Rage LT Graphics chipset, the powerbook wasPowerbook Wallstreet ports supplied with  4MB onboard SGRAM, providing support for up to 1024×768 resolution on a 13.1 or 14.1 inch screen. On the lower 12.1 inch STN screen however, the resolution was limited to 800×600 and supplied with only 2MB of SGRAM.  The Wallstreet “PowerBook G3 Series” has 2D/3D graphics acceleration and “zoomed video” support. An external video port was included, allowing for the connection of an SVGA equipped monitor (PC monitor or Apple Monitor).


As noted above, the wallstreet was supplied with dual Card Bus slots.  It also incorporated ADB, a single Geoport (modem/ printer), ethernet, HDI-30 scsi port, s-video out, external SVGA (Dsub15) monitor port and both sound in and sound out ports.
