[sdiy] Prophet 5 memory expansion mod

[harrybissell at wowway.com]

I modded mine by adding a three way toggle switch to move the
chip select lines and adding an extra RAM chip. The 3.2 uses
a memory buffer so you can switch programs from one bank to
another. I assume that if you move the switch in the middle of
a memory move, you are hosed !!!

You select a bank with the switch, then the prophet thinks that is
the ONLY memory...

Its really not that hard
