What
another BP 145b buyer says: "The PB arrived
in good condition and runs perfectly, thank
you." Stefan G. - Germany
Here you find
other Apple and Mac Collectors Items.
PowerBook 145b - Code Name: Pike's Peak - tested.
System 7.1 (german - can be replaced) and 8 MB
RAM. The akku battery does not work anymore (but
included) and the PB needs to be powered by the
supply (no original, 220 volt - included). Good
optical and technical condition,
see the photos. Due to the age I sell it without
any guarantee.
The PowerBook 145b replaced the PB 145. The
PB 145 has an 8 MB memory ceiling (installed)
, although you can go beyond that by using Virtual
Memory. Another option is RAM Charger 8.1, which
offers better memory management than the Mac OS.
The 145B was discontinued in July 1994. The 140,
145, and 145B were the first PowerBooks to include
an internal floppy drive. They have 10" black
& white screens which are suitable for viewing
text or spreadsheets, but are not really designed
for viewing graphics. These PowerBooks were the
first mass-distributed 'Books and were likely
to be found in your local Circuit City or other
computer store back in the early 1990's. Of the
three, the 145B is the best buy with its larger
hard drive and more memory.
The PowerBook 145B has a single motherboard expansion
slot addressed along a 32-bit memory bus. This
computer requires standard 100ns pseudostatic
RAM modules (PSRAM) in either 2MB or 4MB capacities,
as it shipped in a 4MB default configuration with
one vacant expansion slot. While the PB145B accepts
memory that is compatible with the earlier PB140,
PB145, and PB170, it would be helpful nonetheless
to mention the model number in the Comments field
of the order form when purchasing PSRAM upgrade
modules.
While the PowerBook 140, 145 and 170 all share
a common motherboard architecture with 2MBs of
soldered PSRAM and a 2MB PSRAM expansion card,
the PB145B includes 4MB of soldered PSRAM,
which enables expansion beyond 4MB without the
necessity of wasting a 2MB PSRAM expansion card.
The Motorola 68030 on the PB145B daughtercard
runs at 25 MHz, but lacks a Motorola 68882 FPU.
One peculiarity of the PB140, 145, 145B and 170-series
is that they do not support SCSI Disk Mode. All
four of these PowerBooks address memory along
a 32-bit data path.
