Why does it have to be close to the Soundlogic board? That was a fairly standard breakout board; a currently-produced board won't be much different. If you're looking for something that runs from a parallel port, you'll be stuck with old and obsolete equipment. You'd do better to get a USB or ethernet adapter and bypass the parallel port altogether. Warp9 (makers of the Smoothstepper adapters) has a list of BOBs on their site: https://warp9td.com/index.php/bob-vendors
