The PowerBook 170 was released by
Apple Inc.in 1991 along with the PowerBook 100and the PowerBook 140. Identical to the 140, it was the high end of the originalPowerBook line featuring a faster 25MHz Motorola 68030processor with Floating point unit(FPU) and a more expensive and significantly better quality 10" active matrixdisplay. It was replaced by the PowerBook 180in 1992.
Though the PowerBook 100 is the direct descendant of the
Macintosh Portablebased on its internal architecture, the 170 is the Portable's direct successor. A no compromise portable version of the desktop Macintosh, the 170 includes virtually all of the features incorporated in the original Portable, as on a comparable desktop of the day, but in a smaller and sleeker case design. Initiated as a more suitable replacement for the Portable, the only features the first generation 170 did not include in its reduced space were an external video port and internal ROM& PDSexpansion slots. Indeed, Apple canceled its own external monitor adapter for the Portable shortly after it was announced, instead relying on numerous third party providers for solutions (still applicable to the 170) and FCC regulations of the day prevented any real use of the PDS expansion slot, by restricting any external connections to it. The PowerBook 180replacement would address external video less than a year later, but expansion slots would not return to Macintosh portables until 3 years later with the PowerBook 500series, in the form of PCMCIAcards. The 170 also dropped the external floppy disk port (only the Macintosh Classic IIstill had one) and made no provision for a second internal floppy disk port (a feature also missing from the rest of the desktop line by this time). Overall, it had roughly the equivalent features and performance of the powerful Macintosh IIcidesktop in a laptop.
The 170 was introduced with System 7.0.1, specifically to support new power management and other unique hardware features. However, due to the RAM prices in 1991, combined with its already high list price, the 170, like the 100 & 140, only had 2MB RAM soldered directly onto the logicboard, which critics felt was restrictive for use with System 7. Further, since localized versions of System 7 were not yet available worldwide, the Japanese 6.0.7
KanjiTalkversion of Apple's System software, was modified to support all three new PowerBooks and released as version J-220.127.116.11. [System J-18.104.22.168 ReadMe, 1991, Apple, Inc.] [ [http://translate.google.com/translate?hl=en&sl=ja&u=http://apple.ism.excite.co.jp/page/PowerBook%2B170%2BSpecial%2BEdition.html&sa=X&oi=translate&resnum=3&ct=result&prev=/search%3Fq%3D22.214.171.124%2B%2522powerbook%2B170%2522%26num%3D100%26hl%3Den%26safe%3Doff%26client%3Dsafari%26rls%3Den%26sa%3DG%26pwst%3D1 http://apple.ism.excite.co.jp/page/漢字Talk+6.0.7.html] ] As a result, this version was unofficially adapted for use with the standard 6.0.7 allowing many users to run System 6 on their PowerBooks, rather than upgrading on-board RAM with an expensive proprietary RAM card (a 6MB card was US $899). [ [http://school.anhb.uwa.edu.au/personalpages/kwessen/web/misc/powerbooksys6.html System 6 on a PowerBook 140/170 ] ] The 170 shipped with an additional 2MB RAM card already installed, so it was less of a problem, however 4MB was the minimum recommended RAM size for use with System 7 and not practical for use with a RAM Disk, a battery power-saving feature.
Though released at the same time as the
PowerBook 140and PowerBook 100, both the 140 and 170 were designed entirely by Apple, while the 100 was being miniaturized by Sony from the full-sized Macintosh Portable. As a result, the 170 represents the very first created by Apple, with the 100 actually representing the first design improvements, though its internal architecture is the oldest in the series.
