在笔记本发展的初期,由于多项技术还不成熟,因此这个过程中也出现过不少的败笔之作。这款Zenith公司在1989年所推出的Minisport ZL-1就是其中的一款,现在甚至有人认为,正是由于当年这款Minisport笔记本的推出而导致了Zenith公司的溃败。
由于业界当年还没有彩色显示屏,加上当年液晶屏的价格极其昂贵,为了降低成本,这款Zenith Minisport就尝试使用了类似于电子手表那样的背光屏幕设计,不过在它上市后就发现,这样的显示屏无论是在白天还是黑夜都难以阅读屏幕上的文字,这无疑是对用户得一种折磨。另外,这款机器也并没有内置硬盘,只能使用软盘进行数据储存,所以就算在当时来说这款笔记本都算是比较落后的。不过,事物是在不停的探索然后才能向前发展的,或许如果没有这款笔记本的失败,人们也不会继续坚持在笔记本中使用液晶屏吧!

详解编辑本段回目录
As the only computer to ever incorporate the 2-inch floppy drive, the Zenith Data Systems (ZDS) MiniSport is also the smallest Zenith laptop ever.
The tiny 2-inch floppy disk was originally developed for floppy disk-based digital cameras, but it's diminutive dimensions make it the perfect choice for this portable system.
The MiniSport can boot from the floppy drive, ROM drive, or the selectable battery-backed built-in RAM disk. A portion of the system memory can be set-aside as a RAM disk, to retain user data or other important information.
Since the MiniSport is the only computer system to utilize a 2-inch floppy drive, this is a major hindrance to software installation and the transfer of data to other computer systems. But there is one salvation - FastLynx, permanently installed in system ROM.
FastLynx allows you to conveniently transfer files and directories from the MiniSport to another MS-DOS based system via the serial or parallel port. Magically, no other software needs to be installed on the remote system, the MS-DOS command "CTTY" is all that's required for the transfer to take place.
Options:
As on all Zenith laptops, the user can break into the "machine-language monitor" by pressing <Ctrl><Alt><Insert> at any time. This allows you to trace or resume program execution, change machine settings, run diagnostic routines, or boot from a specific drive.
Later systems, the MiniSport HD, replaced the 2-inch floppy drive with a 2.5-inch internal hard drive. The system shown above has a Conner CP-2024 20Meg HD installed. The MiniSport HD also runs at 10MHz instead of 8MHz.
