[Color Computer][Coco] DLOAD mystery

[Bob Devries]

George,
I have seen the mechanical switch selector setup you're referring to, and it 
was not implemented using the RS-232 port, but rather the cassette port. The 
controller could send the file to "all" or select a particular output to 
send to.

The "master" computer was the only computer in the classroom with any 
storage capability, usually in the form of a single floppy drive, and the 
"student" computers were all connected to the control box via the cassette 
port, and the relay of the "student" computer controlled an LED to show that 
the student had typed the required CLOAD or CLOADM command.

A friend and I wrote a rather involved programme to give the teacher more 
user-friendly control over the "master" computer, doing much of the work of 
selecting and sending the files for him.
