LEDIP 6502 Text Editor

[djrm]

I discovered this memory resident line based text editor in an old Dr Dobb's Journal pdf, when looking for a usable listing or source file I found this on Github: https://github.com/netzherpes/LEDIP

It should port easily onto one of the 6502 monitors I have and I'll be giving it a try shortly. I was really looking for something similar for 6809 but this is a good start.

There is something similar built into the AIM65 so perhaps this will be usable with a single line display but I'll concentrate on getting it to work with serial I/O to start with.

Eventually I'l like to build something similar into a rom bios.

Best regards, David.

The editor works with minimal modification, I just needed to provide the character input and output functions. sample session:

Perhaps the editor output could be used as an input stream to something, an assembler maybee. David.
