I've been playing with the 2x24 LCD screen that TS supports with the
header.

I've got the beginning of an ANSI driver for the screen, but I have
one question...

Jim Jackson's page and his lcdd code seem to indicate that there is an
80 byte buffer for the characters, split between the two visible
lines. And indeed, if you set the cursor on position 40, it goes to
the first position of the second line.

But then if you try to move it, it sits there until the cursor
position reaches 64, and then it starts to move again.

In other words it is acting as if ther is a 128 byte buffer, split
between the two lines, and not an 80 byte buffer.  Possibly the
movement to the second line on cursor position 40 is a bug or kludge.

Has anyone tried to work with the LCD cursor positioning?  Anyone
interested in being a guinea pig for alpha-code and testing an
pseudo-ANSI driver for the screen?  I can't help but think another
pair of eyes might see something I am missing...

I'll post a tarball shortly.
