A few years back, I bought a  upgrade kit for the 600XL which
consisted of two chips which replaced the on board 16K rams
and a bunch of jumpers to rewire the MMU.  I replaced the
chips , but shortly afterwards I lost the jumpers and instructions.

Has anyone done this mod before, and either remember what pins to
connect the jumpers between, or do you still have the instructions
from a kit you might have purchased?
any help would be appreciated.
Thanks in advance.
