GPL CP/M clone
Помоему вместо того чтобы сетовать на недостатки TRDOS-а или пытаться придумать "операционную систему моей мечты" вот с такими красивыми иконками, я думаю имеет смысл посмотреть на замечательную, хорошо продуманную и легко расширяемую операционную систему для профессиональных i8080/Z80 компьютеров. Называется CP/M, в СССР была широко распространена на популярных мини-ЭВМ Роботрон. В спектрум-клонах есть несклько вполне удачных реализаций (Кворум, Профи, АТМ и ТУРБО 2+). Но видимо интереснее свои иконки рисовать...
