[Coco] The early days of Hacking and Coding a CoCo Was: Here's a CoCo 1 ...

[Steve]

And we have a winner!

I just used a common data terminal of the time that had a extra 
keyboard.  (So it setup like a another monitor.)

Datasoft got a early version of the EDTASM cart and I patch the to send 
the CharOut to both the display and the CoCo's serial port.

What most people did not know is that EDTASM had it own display drivers 
that emulate a Terminal.  Why?  Microsoft's EDTASM was design to use a 
terminal to control the cursor for editing a text line.  So, sending the 
CharOut to the terminal worked without modifying anything else in EDTASM.

I later modify the EDTASM for Disk I/O and other improvements like 
longer symbol names with better tabs, lower case and File includes.
