Compaq lte 4/25 Laptop

I know it's an old. Found it in my parents house. Want to play some old dos games I still have on diskettes. Hard drive is bad and can't seem to find any information on the hard drive to see if I can replace it. Thanks for the response!
 
It should be fairly easy to take the hard drive out. It's also quite possible there is Compaq-specific dongle connector between (hopefully, standard) hard drive interface, and laptop. Post a picture somewhere. If the drive is PATA (40-pin), you might find an adapter to put CompactFlash card instead.

For old DOS games, I've heard people using DosBOX, or other virtual environments.
