IEEE Bushy Tree

The GridLite was less innovative than the earlier Grid versions and was comparable to many other laptops of the time. However, its 4.77 MHz clock rate clearly compromised its performance front of its main 7 MHz competitors, the Toshiba T-1100 Plus, and the Zenith Z-171.

One of its strong points was a new blue/yellow supertwist LCD screen which offered superior contrast and could be viewed from 45 degrees off to the side. The second original feature consisted in eight ROM sockets which allowed to put up to 1 MB of ROM software in the machine, including specific GridLite ROM cartridges.

One peculiarity of this ROM area was that both ROM software and 3.5" built-in floppy disk drive were called A:. This allowed, for example, the system to boot on the MS-DOS in ROM and automatically call the Autoexec.bat, Config.sys or any application file from the diskette. [1]
