5 foot long PATA cable from Cat5e


Not one to be constrained by specifications, Montac decided to construct an ATA cable that was well over the 18 inch maximum length.  PATA cables use 80 conductor wire, even though they only have 40 pin connectors. The extra 40 lines are all tied to ground. The cable was constructed from 10 pieces of Cat5e with one line from each twisted pair going to ground. The construction is as tedious as it sounds and at each end there are a few signal lines that also need to be pulled to ground. Once the cable was finished with heat-shrink tubing it was tested. The cable performed as well as, if not slightly better than the standard cables.
