Yes we stock and sell used and refurbished laptops with Windows 98. To many this may sound silly but we do have customers whose applications require older laptops running either DOS, Windows 95 or Windows 98.
Many are used for programming other equipment in the field or for controlling machinery. Low powered applications but important nonetheless. Usually they require a serial port, floppy and hard drive on the laptop. Nothing fancy but gets the job done.
Contact us to check on current stock. Even if we don’t have the right one, we can generally get one for you.
