Subject: Atari console corruption
Date: Wed, 13 Oct 2010 21:10:29 +0200	[thread overview]
Message-ID: <AANLkTimZ4q3mGhy27qVo5gQHMCM2U8jrc_fNPH4YUXev@mail.gmail.com> (raw)

If your shell command line looks like:

sh-3.1# abcd

Then insert another 'b' in front of the existing 'b'. The 'c' will
become corrupted.
The actual characters don't matter, except that the inserted character must be
the same as the existing one.
It happens in all even columns, so if your prompt is different, just try it at
a different even position.

It happens in frame buffer depths 2, 4, and 8. In monochrome mode the corruption
is different. In 16 bpp, when it uses the cfb code, there's no
corruption, so the bug
must be in the Atari-specific code.

I could not reproduce it in vi, only in bash.

Tested on ARAnyM only.

when I'm talking to journalists I just say "programmer" or something like that.
