Hey, I hear the same sounds on my Sony HB-G900P! Indeed, e.g. you can clearly
hear the computer move a block from RAM to VRAM (in e.g. Ruby & Jade), and you
can hear other copy-commands too. Also drive-operation and such.. Quite funny.
I always use it to check if the MSX is hanging or not...! Too bad I can't hear
it anymore since I got my harddisk online, since this thing makes noise like
hell! (Like a coffee-grinder!)
