[Coco] coco1 - 26-3003A

[Bruce W. Calkins]

Early CoCo 1s had raised lettering above the ports in the rear.  Those 
photos show the screen printed lettering.  That should be one of the later 
CoCo 1s.

Now the introduction of a model number does not show when they stopped using 
that model number or what board was inside.  The 26-3003 (n/a equaling 
suffix information not listed?)  Some answers will have to wait until you 
have the item in hand and can check the output and/or open it up.
