Cyclone 40 Design Updates and Kit Changes
MODIFICATION NOTE 1:
Purchasers of the original version PC boards (no revision notice printed on the boards) must make the following modifications during
installation of U1 and U4: Prior to installation, trim the legs of U4-5, U1-6 and U1-16 just short enough so they do not extend below
the plastic body of the IC
Solder a jumper connecting U1-6 to U1-16 over the top of the IC prior to installation. A resistor lead will work.
Cut a 1 3/4” length of 26 AWG magnet wire, and strip the insulation 1/16” back from each end. Solder one end to U4-5
prior to its installation. Install U4 and solder the other end of this wire to TP-1.
