[TRS] TRS80gp v2.4.9

Emulator "szarej" serii maszynek Tandy Radio Shack (Model I, II, III i IV) został zaktualizowany. Ten mocno rozbudowany program jakoś bokiem uchodzi mojej uwadze, cóż maszynki TRS są praktycznie mi obce. Dla chcących potestować emulator odsyłam do strony projektu a po soft dla modelu III warto odwiedzić ten adres.
