Description

Just for fun, I entered Cobado in the Retrochallenge Content. There are some great projects running:

Cobado is a "CoCo Backdoor BIOS". The idea is to run an ultra small generic BIOS on a Colour Computer which can be used to add full remote file access to a Windows system.

The BIOS is under 255 bytes and fits into the cassette buffer. It hooks into the CoCo's line input (vector 12) and returns the command line to the server via the Becker port. The server is then able to take over the CoCo to provide any command set it chooses.

Currently you can navigate Windows, load/save BASIC & binary programs.

The next version will replace the Becker port with RS232, so the system will run on a stock standard Colour Computer.

Future versions will enable executing system commands. ie: Assemblers, compilers, etc. This will enable fast, safe, software development within the CoCo environment.
