Color Computer 3 Text Mode Study

I decided to run thru the complete 40 column text mode options on a CoCo 3. Documented with pictures. Here is the program I used to create the display:

10 CLS
20 FOR X = 0 TO 30
30 PRINT
40 PRINT X;
50 FOR Z = 65 TO 75
60 PRINT CHR$(X+Z);
70 NEXT Z
80 NEXT X
90 FOR X + 0 TO 7
100 LOCATE 0,0:PRINT X
110 POKE &HFF98,X
120 A$=INKEY$:IF A$="" THEN 120
130 NEXT X
140 GOTO 90
