RE: A85: Link Port

easy but annoying way to do this:

setup a tsr (like the background thingy in rigel) such that I'll display
like 4 memory places ont he screen (in the middle?) in menu text so it'll
be small. constanly update this like ever second (not ever interupt caled
becasue this woudl be slow =(  )  use the + and - buttons to move the
memory rectanle up and down. test the memoryplaces by goign to differnt
screen. what do you guys think? If somebody will figuire out the differnt
places and their valesu adn where that is stored in memory I'll put
together a nice TSR options program which will allow you to turn off
features and only turn them back on with password protec. what do you guys
think? =)
