It might be easy enough to make your own buffer board. It just needs one or two 74xx24x buffer chips, voltage regulator (maybe), a few capacitors, some pull-up resistors, and instead of DB-25's, some 26 pin dual row connectors, all on a perfboard. You may be able to piggy back the board onto a parallel port PCI card, or build it on a PCI perfboard with a short ribbon cable(s) to the parallel port card. You would need enough PCI slots, but I don't carry my CNC around with me on a key chain, so I tend to use ATX motherboards with plenty of slots. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
