NEMOIDE implementation, work with 3.5/7/14 MHz Z80 freq (14 unstable), fixed trdos disk reading/writing in turbo modes (when trdos trap active - cpu clock switch to 3.5 MHz), swapping fdd (A ->B) now disabled, must be implemented by swapping corresponding bits of port xFF (trdos), ISDOS boot software is added, isdos hdd image is added.
