Vintage Sharp EL-5100S Scientific Calculator Works Great!
This Sharp EL-5100S calculator is in overall good vintage condition. I tested it to the best of my ability and everything worked great. If there is a specific test you want me to run, just let me know and I will be happy to run it.
Three flaws were noted. Photographs show details of these issues.
1. There is light scuffing on the back of the case as can be seen in the photos.
2. There is some bleeding on the top left side of the screen.
3. Two screws hold the back of the case to the front and one screw is missing. This does not affect performance and should be easy to replace.
A pdf instruction manual is available on request.
