TS-UGOS for TheoryPDA

TS-UGOS for TheoryPDA is the discontinued TS-UGOS-based operating system for the TheoryPDA PDAs produced by Theorysonic from 1991 to 1997.

TS-UGOS for TheoryPDA was written entirely in C++ and trimmed to be low power consuming and use the available memory efficiently. Many applications were pre-installed in the ROM of the TheoryPDA (making for quick startup) and to save on RAM and flash memory storage for user applications.

History
TS-UGOS for TheoryPDA started development roughly the same time as TheoryPDA.

In 1997, TS-UGOS for TheoryPDA was discontinued and replaced by Portosic OS.
