The PowerBook 140 was released in the first line of PowerBooks. It was the mid-range PowerBook, between the low-end 100 and the high-end 170. As with the PowerBook 170, and unlike the 100, this PowerBook featured an internal floppy drive. Codenames for this model are: Tim Lite, Tim LC, Replacements, and Leary. In 1992, it was replaced by the PowerBook 145, which was essentially a speed bump, though the PowerBook 160 essentially superseded it as the new mid-line model.

Features

Intended as a replacement for the Portable, the 140 series was identical to the 170, though it compromised a number of the high-end model's features to make it a more affordable mid-range option. The most apparent difference was that the 140 used a cheaper, 10 in (25 cm) diagonal passive matrix display instead of the active matrix version used on the 170 that had better readabilitty. Internally, in addition to a slower 16 MHz processor, the 140 also lacked a Floating Point Unit (FPU) and could not be upgraded. It also came standard with a 20 MB hard drive compared with the 170's 40 MB drive.

The 140 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 140, like the 100 and 170, only had 2 MB RAM soldered directly onto the logicboard, which critics felt was restrictive for use with System 7. Furthermore, since localized versions of System 7 were not yet available worldwide, the Japanese 6.0.7 KanjiTalk version of Apple's System software, was modified to support all three new PowerBooks and released as version J-6.0.7.1. [3] [4] 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 2 MB card was US $300). [5]

Design

Though released at the same time as the PowerBook 170 and PowerBook 100, both the 140 and 170 were designed entirely by Apple, while the 100 was miniaturized by Sony from the full-sized Macintosh Portable. As a result, the 140 represents the very first notebook computer created by Apple, with the 100 actually representing the first design improvements, though its internal architecture is the oldest in the series. 140 was designed by Gavin Ivester of the internal Apple Industrial Design Group.

PowerBook 145

The PowerBook 145 was a speed-bumped 140, increasing the processor speed from 16 MHz to 25 MHz. The standard hard drive was upgraded from 20 MB to 40 MB. The 145 also introduced a new feature for the battery-conscious: users would be able to configure the 145 to sleep or completely shut down whenever the clamshell unit was closed. Though a direct descendant of the 140, the 145 was actually the replacement for the PowerBook 100 as the low-end model, the 140 having been superseded by the new mid-level PowerBook 160.

It was replaced by the PowerBook 145B in June 1993. The only codename for this model is: Colt 45.

PowerBook 145B

The PowerBook 145B was the same as the PowerBook 145 that came before it, but with a lower price and additional 2  MB of RAM soldered to the motherboard. The only codename for this model is Pikes Peak.

Unlike previous Mac models but like the Performas, the 145B did not ship with a full set of system disks. System 7.1 was preinstalled on the internal hard disk, and a single system startup disk was included. The package also included two utilities that provide basic backup and restore functions. Although the 145B shipped with System 7.1, it can, in fact, run System 7.0.1, however it will incorrectly report as a 140 in “About This Macintosh...”

The 145 was superseded by the PowerBook 150 as the next low-end PowerBook.

According to Apple, all of these models are obsolete. [lower-alpha 1] [6]

The PowerBook is a family of Macintosh laptop computers designed, manufactured and sold by Apple Computer from 1991 to 2006. During its lifetime, the PowerBook went through several major revisions and redesigns, often being the first to incorporate features that would later become standard in competing laptops. The PowerBook line was targeted at the professional market. In 1999, the line was supplemented by the home and education-focused iBook family.

The Macintosh Plus computer is the third model in the Macintosh line, introduced on January 16, 1986, two years after the original Macintosh and a little more than a year after the Macintosh 512K, with a price tag of US$2,599. As an evolutionary improvement over the 512K, it shipped with 1 MB of RAM standard, expandable to 4 MB, and an external SCSI peripheral bus, among smaller improvements. Originally, the computer's case was the same beige color as the original Macintosh, Pantone 453; however, in 1987, the case color was changed to the long-lived, warm gray "Platinum" color. It is the earliest Macintosh model able to run System Software 5, System 6, and System 7, up to System 7.5.5, but not System 7.5.2.

The Power Macintosh G3 is a series of personal computers designed, manufactured, and sold by Apple Computer from November 1997 to August 1999. It represented Apple's first step towards eliminating redundancy and complexity in the product line by replacing eight Power Macintosh models with three: Desktop and Mini Tower models for professional and home use, and an all-in-one model for education. The introduction of the Desktop and Mini Tower models coincided with Apple starting to sell build-to-order Macs directly from its web site in an online store, which was unusual for the time as Dell was the only major computer manufacturer doing this. Apple's move to build-to-order sales of the Power Macintosh G3 also coincided with the acquisition of Power Computing Corporation, which had been providing telephone sales of Macintosh clones for more than two years.

The Macintosh Quadra 605 is a personal computer designed, manufactured, and sold by Apple Computer from October 1993 to July 1996. The model names reflect a decision made at Apple in 1993 to follow an emerging industry trend of naming product families for their target customers – Quadra for business, LC for education, and Performa for home. Accordingly, the Performa 475 and 476 was sold in department stores and electronics stores such as Circuit City, whereas the Quadra was purchased through an authorized Apple reseller.

The Macintosh Quadra 650, originally sold as the Macintosh Centris 650, is a personal computer designed, manufactured and sold by Apple Computer from February 1993 to September 1994. The Centris 650 was introduced alongside the smaller Centris 610 as the replacement for the Macintosh IIci and Quadra 700, and it was intended as the start of the new midrange Centris line of computers. Later in 1993, Apple decided to follow an emerging industry trend of naming product families for their target customers – Quadra for business, LC for education, and Performa for home – and folded the Centris 650 into the Quadra family.

The Macintosh LC 500 series is a series of personal computers that were a part of Apple Computer's Macintosh LC family of Macintosh computers, designed as a successor to the compact Macintosh family of computers for the mid-1990s mainstream education-market. The all-in-one desktop case is similar to the then recently introduced Macintosh Color Classic, but the LC 500 series is considerably larger and heavier due to its larger screen and a bulging midsection to house the larger electronics, including a 14" CRT display, CD-ROM drive, and stereo speakers.

The PowerBook 100 is a notebook-sized laptop computer designed and manufactured by Sony for Apple Computer and introduced on October 21, 1991, at the COMDEX computer expo in Las Vegas, Nevada. Priced at US$2,500 with external floppy drive, the PowerBook 100 was the low-end model of the first three simultaneously released PowerBooks. Its CPU and overall speed closely resembled those of its predecessor, the Macintosh Portable. It had a Motorola 68000 processor at 16 MHz, 2-8 megabytes (MB) of RAM, a 9-inch (23 cm) monochrome backlit liquid-crystal display (LCD) with 640 × 400 pixel resolution, and the System 7.0.1 operating system. It did not have a built-in floppy disk drive and was noted for its unique compact design that placed a trackball pointing device in front of the keyboard for ease of use.

The PowerBook 180 is a portable computer released by Apple Computer along with the PowerBook 160 in October 1992. At the time, it constituted the new top-of-the-range model, replacing the previous PowerBook 170. Its case design and features are the same as that of the 170, but it shipped with the more powerful 33 MHz Motorola 68030 CPU and Motorola 68882 FPU. Along with the 160, it introduced a new power-saving feature which allowed the processor to run at a slower 16 MHz rate, the same speed as the original 140.
