Comparing it against the 1.2 version of Color Basic, I find the following
differences:

1.  Version number changed to 1.4.
2.  Copyright year changed to 1985.
3.  Changed configuration code for the SAM (supports only 16K or 64K DRAM).
4.  Disables the "fast" keyboard test similar to CoCo 3 Basic.
5.  Changes number of cassette leader bytes from 128 to 256.
6.  When searching for a cassette file, skips bad "Name" blocks rather than
?IO ERROR.
7.  Changes "CLR 8"  to  "CLRB"  at $A95E  (a long-standing minor bug).
8.  Changes "STA 0,X"  to  "STA  ,X"  at $B55A.
9.  Replaces the "Garbage Bytes" (MICROSOFT! easter-egg) with zeroes.
