At 8:20 Eastern Standard Time, Oct. 30, there is a typo in the source
code. I'm not sure about the distribution disk programs.
The code should read:
* COMBINE EXTENDED DATA WITH 6 BIT SAMPLE
TFR Y,D
LSRA
RORB
TFR D,Y
LDA DAC64
ANDA #^2 !!!!!!!!!!!!!!!!!!
Depending on your assembler that can be changed to ANDA #.NOT.2 or
ANDA #%11111101 .
Nick has been notified and the code may be corrected by the time you
look at the web page. :)
