THINKPAD 385XD (2635) specifications

The IBM ThinkPad 385XD (2635) is a classic laptop that emerged in the late 1990s, designed to cater to business professionals and technology enthusiasts alike. Known for its robust engineering and solid performance, the 385XD encapsulated the trusted ThinkPad ethos that IBM established in the laptop market.

This model features a 13.3-inch TFT display that provides a resolution of 800x600 pixels, which was considered adequate for its time.

The ThinkPad 385XD boasts a compact and lightweight design, making it portable for professionals on the go.

Under the hood, the 385XD is powered by Intel's Pentium MMX processor, offering clock speeds up to 233 MHz. This CPU, coupled with the laptop’s 32MB of RAM, delivers satisfactory performance for typical office applications and multitasking needs at the time. For enhanced productivity, the system supports an upgrade of up to 128MB of RAM, allowing users to improve performance as software demands increased.
