IBM ThinkPad 770

IBM ThinkPad 770 was a laptop designed and manufactured by IBM targeted for the business, enterprise and professional user. It was the last lineup in the ThinkPad 700-series, succeeding the 760 as the high-end laptop of the ThinkPad lineup. The line was produced from October 1997 to October 1999, and eventually replaced by the ThinkPad models 390X and 600X.
Features.
The first 770s were shipped with either Windows NT4 or 95, but later shipped with 98 pre-installed. They were equipped with IBM's Ultrabay II, allowing for the option of either a CD-ROM, floppy drive or 2nd battery. 
One notable feature of the ThinkPad 770 is that it was the first laptop available with a DVD-ROM option in addition to a USB port and AC-3 support.
The first 770s featured an Intel Pentium I processor running at 233 MHz but with an optional 266 MHz upgrade. Later models introduced the Intel Pentium II mobile processor, and because these 770s use a certain processor socket, many have had success installing much more powerful processors generating up to 850 MHz. Although most models run at the 1024x768 resolution, some later models are capable of the 1280x1024 resolution. All use Trident Cyber 9397 graphics chips with 2mb memory in the 770 and 4MB memory in the 770E/770ED and up.
Reception.
The ThinkPad 770 won the Technical Excellence Award by PCMag in December 1997.
