Shown here is a Thinkpad 765D in not the best condition, but still very good working condition.
The Thinkpad 765D is regarded as the last and the best of the Thinkpad 760, one of the more well known collectible vintage Thinkpads. The Thinkpad 760s tend to be set apart in the realm of vintage laptops due to their extensive ability to be configured by the end-user in the field, with a modular design allowing fast swapping of Hard Drives, Batteries, and the "Ultrabay" which was capable of being swapped between a Floppy Drive and a CD-ROM drive depending on the model you had. This was a significant development for mobile computing at the time, and makes for a very interesting old retro machine in your collection. The 765D in particular was launched in 1997 and was equipped with a 166MHz Pentium MMX CPU, standard 32MB of RAM (8MB of which was soldered onboard), a 3GB HDD, and the main differentiating feature from other 760s was the 13.3" 1024x768 TFT Color display, with a physically larger construction to fit the bigger panel. The previous 760s such as the 760XD had a 12" display and were physically smaller.
The 760XD tends to be the more sought after 760 model Thinkpad, since it physically resembles all the other 760s and has the most powerful hardware out of all of them. Both the 760XD and 765D are considered to be quite rare, but the 765D is quite an oddball since it is physically different from the others and has similarly configured hardware to the 760XD. It tends to not see as much attention as other vintage Thinkpads, but I personally find it to be one of my favorites.
