Looking for DOS educational games from Davidson & Associates

[plinkoplus]

Hi All,

 

I am looking for the original educational DOS games from Davidson & Associates, particularly the Blaster series of games such as Alge-Blaster, Alge-Blaster Plus, Science Blaster, and others.

 

These games were made in the 1980's.

 

If anybody can point me in the direction where I can buy or download those games or if anyone wants to sell those games, please let me know.

 

Also could somebody give me a list of all of those games.

 

Any info is greatly appreciated.

 

Thanks in advance.

 

Yours truly,

Chris
