sort of in the same vein, i have a slight annoyance with drive light.

i have written a routine to play digital samples thru the speaker (who
hasn't?) which uses a lineA variable to check the mouse button status
to find out when to quit playing the sample. only trouble is the drive
lite comes on and off intermittantly (mega 4, tos 1.2). if i recall, it
set SR to $2700 (disable interrupts). it doesn't seem to cause any
problems but i'm sure users are going to question it. i know i can always
do a Dfree or faster op to clear it, but was just wondering what was
going on. the sound chip also controls something with the floppies so i
save and restore some register to make sure things are cool. maybee i need
a delay before i restore? this only started happening when i started tracking
the mouse button state (button up, stop).

thanx...
