My charge pump is being feed by a parallel port buffer which is a 54HCT541. There isn't much to see but it's shown here: http://www.wallacecompany.com/machine_shop/Shizuoka/00011-1a.jpg The breadboard on the left has the buffers and opto-couplers. The left board has the charge pump and a circuit from a totally different project.
