INTRO

Mr.Fiz/Samar has developed a memory expansion for C64, namely +60K. It is somewhat popular in
the demoscene community. Unfortunately it works only on C64, not C128.
That is why I've slightly enhanced his work and this is the effect - +60K for C128. It has
this advantage that C128 already has additional memory onboard and only some fiddling with
enabling signals was needed.

Expansion is pretty easy to build, I used 'piggy-backing' method with a couple of wires, but
someone might develop full-featured PCB.

Before building read notes on the schematic.
