SDLTRS v1.2.24 is released. SDLTRS is a Radio Shack TRS-80 Model I/III/4/4P emulator for Macintosh OSX, Windows, and Linux. SDL(2)TRS is based on Tim Mann's excellent TRS-80 emulator xtrs and also has very low system requirements: it works on all platforms supported by the SDL library, even on machines with only a few hundred MHz of CPU speed.
