This is a very fast Win98SE gaming machine with 32 Bit graphics, USB 2.0 ports, a DVD-ROM drive, and 512MB RAM, which is plenty for the OS.
Google "windows 98 gaming laptop reddit" and the first result is "The best Windows 98 laptop you can get! ThinkPad T41/T42..."
The 1.8 GHz Pentium M makes this laptop fly compared to the original Win98 Pentium II and PIII based machines.
This machine has the hard-to-find Radeon 9000 GPU for higher resolution than most T41/T42s with a Radeon 7500, andhas working sound and video drivers, etc. which can be tricky to find.
Office 2000 (including Clippy), Adobe Photoshop 7.0 and Reader 6.0, After Dark, Doom 2, Wolfenstein 3D, GTA1, Sim City, and The Sims 1 (with CD) are included. DOS games may not have audio. Install DOSbox if you want audio.The battery is at 40% of new capacity. A charger is included for AC power. The CMOS/RTC (clock/backup) battery is new. The WiFi card driver is not installed since it is not compatible with modern security, nor is Win98. If you need WiFi, I can recommend a USB or Cardbus solution that works with WPA2 encryption.The top has some minor scratches and scuffs.I have not tested anything external besides the DVD drive and USB ports.
Pretend it's 1999.
