Actually any flea power diodes should work. Assembly is quick and
requires soldering wires and diodes between the DB-25P and the edge
connector; refer to the attachment standard. Be sure that the diodes
are oriented correctly. Improper orientation will not damage the PET,
but the joystick buttons won't respond as planned. Plug the edge
connector onto the back of your PET (it's the center slot); be sure
it's properly oriented. Plug your joysticks into the DB-25P. Turn
the PET on and you're off and running!

The SNAKE program was originally written by Pete Rowe of the Lawrence
Hall of Science in Berkeley, and couldn't be better suited for two
joysticks. The author has modified the SNAKE coding for joysticks
and is distributing it with the permission of Pete Rowe and the SPHINX
user group library.
