*) This pin was originally only intended for testing the hardware, directly goes to a I/O pin of
the CPU, and is completely unprotected. Its use is not recommended nor supported – if you
don’t know what that means do not use it!
This Pin can NOT be used as a +5V source, like on the original C64 connector.
