1989年9月：苹果的第一款以电池为电源的Mac电脑，伴随着众人的激动与兴奋，诞生了。但是4英寸厚，16磅重的这个家伙还真是只能勉强算得上“移动电脑”。虽然在当时$6500的售价并不算稀奇，但它的电源很成问题——充电的时候不能使用AC电源工作。
苹果更是不惜重金，为它配置了一个10寸（640*480像素）的屏幕——而当时其他的移动电脑都只有一些很难称得上是屏幕的显示设备。虽然在1991年，屏幕加入了背光功能，但是苹果的其他几项“改进”——包括电池使用时间减半——导致这款移动电脑于当年10月被PowerBook 100秒杀了。
现在，大家来观赏两张Macintosh Portable的照片吧。

Apple Macintosh Portable
The Mac Portable is Apple's first portable Macintosh computer. Although there were already PC laptops on the market, few were as fast or powerful. The Portable has a 68000 processor running at 16 MHz, comes with 1 MB RAM which can be expanded to 9 MB RAM, has an optional internal 9600 baud modem, and includes a PDS slot (Processor Direct Slot) for direct access to the system processor. This allows for faster and more powerful expansion cards.

The Mac Portable is Apple's first portable Macintosh computer. Although there were already PC laptops on the market, few were as fast or powerful. The Portable has a 68000 processor running at 16 MHz, comes with 1 MB RAM which can be expanded to 9 MB RAM, has an optional internal 9600 baud modem, and includes a PDS slot (Processor Direct Slot) for direct access to the system processor. This allows for faster and more powerful expansion cards.
The Portable has an active matrix screen, which updates faster, and doesn't have the blurry effect of other early displays. This new and high-tech screen greatly added to the system price.
To the right, you can see the back-lit Macintosh Portable (model M5126), released in 1991. The original Portable screen was not back-lit, and this new version improves readability in both dark and well-lit environments. Unfortunately, it also cuts the battery life in half, to 6 hours maximum on a single charge.
The Portable is powered by an internal lead-acid gel/cell battery, similar to those found in car batteries, which can run from 6 to 12 hours. The trade-off is that the battery adds an entire 2 pounds to the weight of the Portable.
Data storage is on a Conner 40 MB SCSI hard drive. To conserve power, the hard drive can spin down and sleep, but being a SCSI drive, it cost twice as much as other non-SCSI hard drives from the same era.
There was only one problem with the Portable which unfortunately led to its demise, it just wasn't very portable. Being rather large and weighing 16 lbs, few people had the patience to lug it around anywhere, despite all of its great features.
Two years later, in 1991, Apple released the successor to the Macintosh Portable - the Powerbook 100. Designed by Sony from the original Macintosh Portable schematics and blueprints, the new Powerbook 100 is smaller, lighter, and cheaper than the Portable.
One of my Macintosh Portables is an old one, a demonstration unit, for testing prior to production release!
