This is a clone of the editor of the same name that once was available for the DEC’s RT-11 OS.
It is not identical to the original. In particular, this version implements smart tab handling like the old Borland editors did (the original simply converted all tabs to spaces), and has a different set of screen editing commands which is more WordStar-like.
This version is for a Z80 CPU and runs under CP/M or RSX180. Can edit files larger than the available RAM, up to approx 1Mbyte.
