About the files: COPYSET This text file copper Send to a Postscript printer to get a representation of the copper side of the PCB. silk Ditto for the component placing. This design is built on a single sided board. It assists in copying digital recordings from one source to another, by setting bit two in the subcode blocks to copying allowed. Besides, it reduces jitter in the data stream and allows choosing between four inputs; two coaxial and two optical. It has four outputs simultaneously active. Please note that building this item is recommended only who have experience doing so; while the board design is tested, is has been built only once. The component layout was drawn from the prototype; it has not yet been checked by having a third build from it. This said, you will not be surprised to know that I will not be responsible for any disasters, mishaps and so on arising from either building this device, or from mistakes and/or possible errors in the design. Also take notice that this board could maybe be used in copyright breaching; it is however only meant to be used in a professional context. If you have built this device, and it works, you can of course send me a thank-you with any remarks you might have. My email adress is: ttonino@bio.vu.nl I'd rather have, however, that you donate an amount of ten dollars or more (or equivalent) to a support organization for the diseased - be it a cancer, MS, AIDS or other support group. Good luck, Thomas Tonino
