HSMC pinout for THDB-ADA with Cyclone III starter kit

Yes, I guess the boards pinouts are fitting the starter kit. I found that there are two different issues with ADA HSMC pinout, when you map it to the official HSMC specification, respectively the Altera boards, that are keeping it strictly.

The first point is the mirrored upside-down position, the second the fact, that HSMC uses a 40 pin DP configuration in one bank and a 60 pin standard configuration in the others, resulting in difference of 20 "numbered" pins, with respective gaps in the DP footprint.

Cause Altera has issued an official HSMC reference document, to my opinion Terasic isn't free to use an arbitray pin numbering. At least the different pin numbering must be clearly mentioned in the schematic. The mixed DP/non-DP issue is a built-in confusion of the HSMC standard, the choosen HSMC pin numbering doesn't seem well-considered. It would have been wiser to use the standard connector numbering with gaps in the DP bank, I think.

To prevent from such confusion, the HSMC spec should suggest a numbering scheme for the 20 gap pins as well and require it's usage obligatory upon all implementations.
