There seems to be more differences in in 4000 series hardware. I took some pictures of the area with missing Cyclone IV FPGA and it's surrounding on both sides of the board. Firmware would be puzzled when it fails to find that FPGA that suppose to be there on 1 GHz model. Lots of bypass capacitors and other stuff are missing there as well on 200 MHz model. |

The 4000 series has the extra FPGA installed on the 1 and 1.5 GHz units. |

** parts have been sold ** I decided to sell the parts I had collected for a mod of my 3014T. All are new, from distributors, except for one of the semi's may have been from ebay. |

This is amazing level of hacking! I am wondering if it would be slightly simpler if one starts with a 500MHz 3054T? Would that substantially reduce the number of components that need to be replaced to get to 1 GHz? |
