挑战MacBook？ Cr-48 Chrome完全拆解第1页：Cr-48 Chrome完全拆解1在今年10月，Google启动了pilot program来测试及宣传它的Chrome操作系统，在该计划中，Google展示了特别设计的Cr-48 Chrome笔记本，而近日这款笔记本已经到达国外媒体手中，很快进行了详细拆解，下面就让我们一同来看一看。

外盒：装着Cr-48笔记本的外盒是一个咖啡色的小纸箱，最外层表面的图案走的是怀旧风。

Cr-48外盒的图案是一只白老鼠、一个老鼠专用的滚轮和一个喷射引擎。

打开外盒：英特尔技术卡：硬纸版包装：第2页：Cr-48 Chrome完全拆解2盒子内容：在Cr-48 下面放的是电池和电源供应器。

Cr-48 电池和电源供应器：产品文件：Google 并没有提供Cr-48 Chrome笔记本很多的文件讯息。

打开上盖：Cr-48使用12寸LCD显示萤幕，内建webcam以及全尺寸的键盘。

键盘和触碰版：Cr-48 使用全尺寸的键盘，但却有一些特别之处。

举例来说，键盘上没有Caps Lock 案键，却包含了几个以网路为中心的按键，例如前进、后退及重新读取。

第3页：Cr-48 Chrome完全拆解3欢迎页面：我在开始解剖Cr-48以前先打开电源看看。

上方：Cr-48的外壳是全黑的橡胶塑料。

底部含电池：底部不含电池：型号：Mario根据多个报导来源，Google一直使用一套特别设计的装置名为＂Mario＂或＂Andretti＂在内部测试Chrome操作系统，这个名称来自著名的一级方程式赛车手Mario Andretti。

尽管Google将这批设备正式命名为Cr-48，Mario这个名字还是留在了设备里面，Cr-48这个名称则是指一个不稳定的同位素－化学元素铬。

第4页：Cr-48 Chrome完全拆解4Cr-48笔记本上没有任何关于Google的logo或品牌。

左侧：Cr-48左侧有一个VGA插槽、风扇网及扬声器口。

RSS/CPS/CCS is compatible with IBM XT, AT, PS/2 models 30, 50, 60 and 80.Requires 640K RAM. DOS 3.1 or later. Consult the RSS users guide for the computer configuration and DOS requirements. (ForHT1000, MT/MTS2000, MTX838/8000/9000, Visar and some newer products —IBM model 386, 4 MEG RAM and DOS 5.0 or higher are recommended.) A Radio Interface Box (RIB) may be required as well as the appropriate cables. The RIB and cables must be ordered separately.Licensing:A license is required before a software (RVN) order is placed. The software license is site specific (customer number and ultimate destination tag). All sites/locations must purchase their own software.Be sure to place subsequent orders using the original customer number and ship-to-tag or other licensed sites; ordering software without a licensed customer number and ultimate tag may result in unnecessary delays. To obtain a no charge license agreement kit, order RPX4719. To place an order in the U.S. call 1-800-422-4210. Outside the U.S., FAX 847-576-3023.Subscription Program:The purchase of Radio ServiceSoftware/Customer Programming/Customer ConfigurationSoftware (RVN & HVN kits) entitles the buyer/subscriber to three years of free upgrades. At the end of these three years, the sub-scriber must purchase the same Radio Service Software kit to receive an additional three years of free upgrades. If the sub-scriber does not elect to purchase the same Radio Service Software kit, no upgrades will be sent. Annually a subscription status report is mailed to inform subscribers of the RSS/CPS/CCS items on our database and their expiration dates.Notes:1)A subscription service is offered on “RVN”-Radio Service Software/Customer Programming/Customer Configuration Software kits only.2)“RVN” software must only be procured through Radio Products and Services Division (RPSD). Software not procured through the RPSD will not be recorded on the subscription database; upgrades will not be mailed.3)Upgrades are mailed to the original buyer (customer number & ultimate tag).4)SP software is available through the radio product groups.The Motorola General Radio Service Software Agreement is now available on Motorola Online.
