DOWNLOAD DESIGN

The following is supplied "as is" with no warrenty expressed or implied.

I can't really help with any queries to do with the design, however if you follow the design pages you should be able to sort any problems you may envounter. However, I may be prepared to modify the software to support other standards such as 205, 441 or maybe 525 lines.
