* fix compiler warnings * fix initialisation bug (caused a crash in `cpm80`) * improve debugging * add checkpoint position * add (optional) extensions filter in `flash_filer` * renaming checkpoint file to be filter-friendly (`chkxyz.img`) * bump version
z80cpm
A simple CPM implementation for Linux. This is based on my cpm80 sketch which uses this library.
This implements cpmsim's I/O port interface.
Its primary purpose is to speed up bugfixing of this library's z80 core and its applications, primarily Fuzix.
