It is at $397 for the CBM 6x0/7x0 series and at $383 for the P500.

You could have looked into my kernal disassembly for the CBM 610:-) I'm
also preparing a kernal disassembly for the P500, but I haven't worked on it
for a long time now.

The kernal variable at $F1 contains the attributes in the high nibble. Just
setting it to the color will clear all attributes including the second charset
bit.

Neither. I have removed initconio completely and used module constructors
instead, so the scroll flag is now set in the initialization code if the cputc
module is linked into an application.

I'm not sure if this is really harmless, for example the quote flag is also
set, if a quote character is output. But we'll see once 80 column mode is more
in use. I have adjusted the nachtm sample to use screensize() as a first step.

I don't know that approve/disapprove should do. CVS access is possible, but
since CVS is not really secure, and I had problems adding both, read only and
read/write mode, all I can grant is write mode, and for security reasons, I
will allow that only from known IP addresses. If you have a static IP, CVS
access is no problem.
