Why not use the graphlink?

Also, for those who want more memory, I should mention the
method I use for my 83.  It's a cheap way, cheaper than most
mentioned here so far, to add an extra 32k.  I bought a second
calculator.  That's all there was to it.  Easy as pie.  No
software needed and no hardware mods.  And it's fully expandable
in 32k increments.
