[Coco] CP 400 test

[Roger Taylor]

The following extremely short program assembles to a SS35 virtual disk and 
reads fine from the CP 400 system.  When executed, the letter A appears in 
the top left corner of the nuclear green screen, covering up the P in 
PROLOGICA.  :)

	org	8192
start	lda	#65
	sta	1024
	bra	*
	end	start

It also assembles to an 8K ROM Pak image and works, placing the letter A in 
the corner of a clear screen.

I guess the CP 400 is very similar to the CoCo and/or CoCo 2.
