Hello,

	A note regarding the LASER 128 mode of interlacing.
All you need to is at the machine language prompt (CALL -151)
type C025 to turn it on... and C024 to turn it off.  Someone
mentioned this to me a few months ago (thanks).

	Also, you could use the following boot program on
the Laser.  As the program boots, press CLOSED-APPLE to
turn the mode on... and when running the program again,
press OPEN-APPLE to kill the mode.

------------------------------------------------------------

 50 HOME
100 LA =  PEEK ( - 16287): IF LA > 127 THEN X =  PEEK
    ( 49188 ) : HOME : PRINT : PRINT : PRINT "
    P L A I N  t e x t  m o d e"
200 RA =  PEEK ( - 16286): IF RA > 127 THEN X =  PEEK
    ( 49189 ) : HOME : PRINT : PRINT : PRINT "
    S H I F T  t e x t  m o d e"


NOTE:  This won't look very good at all on screens that
       leave 'after-glow characters'... and it also will
       not look so hot in the 80col mode... although you
       can try.  I have found that using one of those
       polorizing anti-glare screen guards works GREAT!



Cordially,
