Hi,

I know found out how I came up with the $2E00 start address for the Atari :-)

The kermit65 version for the Atari uses $2D20 as start address:

...
;
;       now start at a reasonable place
;
         *=      $2D20           ; about as low as reasonable on atari
;
...

$2D20 sounded a bit "odd" to me, so I took $2E00, with the additional benefit to have some extra safeness.

I found this now while I was browsing some old code (see http://www.cc65.org/mailarchive/2001-02/0377.html,
the current location for kermit65_cc65.0.1.tar.gz is ftp://ftp.groessler.org/pub/chris/cc65, btw.).

I also noticed, that spudster is not online anymore (but I should somewhere have a CD with a mirror of
it which I burned back then :-)). I searched and found the original kermit65 source code still available at

ftp://ftp.pigwa.net/stuff/collections/holmes%20cd/Holmes%202/Atari%20Archives/Telecomm/K65SRC.ARC .

I don't know why John Dunning (the original porter of kermit to the Atari) decided to use $2D20 as start
address. Any ideas?

regards,
chris
