The PowerBook 1400/133 represented the midrange of the 1400
line which included 117MHz and 166MHz models as well. Only
16MHz faster than its 117MHz sibling the 1400/133 gained extra
performance from the inclusion of a 128k level 2 cache. Performance
was roughly 20% better than the 1400/117.

The 11.3" inch screen was available as either dual-scan
or active matrix. The resolution on the 1400 series was bumped
up from the 640x480 of older PowerBooks to 800x600. Many faulted
the video as being too slow and with 1MB VRAM video was limited
to 16 bit. All of the 1400's offered the cool option of adding
a custom back and companies like BookWares.com
were quick to supply them. There are two issues to be aware
of if you are considering a G3 upgrade for this machine, heat
and power consumption. Some have suggested that a G3 upgrade
would run too hot in this machine. The other issue is that
the upgrade will drain your battery roughly 25-75% faster
than without the upgrade. For more information on this issue
and the PowerBook 1400 in general visit The PowerBookSource
website.
