Apogee Software provided both games and tools. Their games included Gravitron, Gravitron II, Froggs, and Robot Battles. Utilities included an Unerase/Undelete file recovery tool.
The company was located in Savannah, GA. I believe the owner was William Gartelmann, Jr. The company was listed in "The BUSS Directory" for 1983 - 1985. They were not listed in the 1986 or 1987. The 1985 issue also listed Walter Clayton as the contact person.
If anyone has contact information for Apogee or William Gartelmann, please contact me at the email address below.
