While the source code to my nanoBug nano debugger is available here: https://github.com/rayarachelian/nanoBug I realize I didn't upload the prebuilt disk images. :o
nanoBug is a tiny debugger that lives in the boot sector a Lisa's floppy. It only works over the serial port. Look at the github page above for documentation and source.
So figured I'd add them here as a shortcut for whoever wants to play with it.
Restore these with either BLU or DiskCopy 4.2 to use on a real Lisa. The file name should tell you the bps (i.e. 38400) and for a couple of them whether hardware handshake is available. The -b signifies serial port B.
Some of them are newer than others, but sorry, I forget which is which. Each disk image is compressed with bzip2 and this whole thing is compressed with tar.xz - not ideal as i
The source on github is the newest one, you can also use https://github.com/rayarachelian/EASy68K-asm to assemble it, etc.
You'd probably want to use this one: nanobug-with-hwhandshk-38400.dc42 in most cases as it's the fastest. But you'll need a hardware handshaking wired DB25 null-modem cable to a modern machine running ZTerm/minicom/qodem, etc.
There's a 57600 one too, but this might not be as reliable.
(Sorry wrote these in 2007, and don't recall which file does exactly what.)
