The following tutorial, along with the entire CGP-115 manual of commands may, one day, appear in the (6)TechRef (D)ownload area under the filename CGP115.DO if "perhaps" some Club 100 member would take the time to key the manual into a file and upload it.
The CGP-115 (Aka: Color Graphics Plotter #115) was a 4-pen printing device sold by Tandy/Radio Shack in the early 1980's. The manual showed examples of how to embed CHR$() codes within a BASIC program but there other ways to drive this printing device; especially from the versatile Model 100 computer family. Driving the CGP-115 from within TEXT mode on a Model 100, 102 or 200 was developed by the late Bill Templeton.
USING THE CGP-115 FROM TEXT MODE ON A MODEL 100 Try this on your CGP-115 plotter from M100 TEXT mode. Insert tabs between the longer string @abcdefghi... for better effect:
It shows how easy it would be to print a spreadsheet sideways, limited only by the number of rows, not columns.
Did you know you can change pen colors and draw straight lines when driving your CGP-115 from Model 100 TEXT mode? All you have to do is to embed print codes shown on p.42-43 in the CGP-115 manual, using the M100 "Control P' function. To print the embedded codes from within TEXT you can not use the
a) To change pen colors in TEXT mode:
^] = <CTRL P><Left-Arrow> = CHR$(29)
b) To enter Graphics Mode:
^R = <CTRL P><CTRL R> = CHR$(28)
c) To draw a box:
^R
D100,0,100,-100,0,-100,0,0
d) To draw a multicolor rectangle:
^R

D200,-50
