These are the file contents of the surviving CP/M-80 diskettes I had saved, copied to internet-ready files around 2005. Bugger is a ROM-based resident debugger for a Z80 that fits in 1K.
Diskette contents listed below. All files are contained in the ZIP file, the whole thing is just over a megabyte.
