There is this which might work for you: http://www.bdmtools.com/bdm-usb.htm But they don't list Mac support. Just off the top of my head, I would have tought that a parallel port BDM combined with a USB parallel port adapter would come close to doing the trick. Then I read this URL http://www.ramelectronics.net/html/usb_printer_cable.htm which states "USB to parallel port converters are for printers only! All-in-one units (printer/fax/scanner) or scanners, zip drives, etc. will not work with any USB to parallel port converter currently available." Hopefully that's a marketing claim but my VERY quick search didn't come up with UCB to parallel adapter that claimed support for anything except printers. If you solved that minor problem, you should be able to trick any parallel port device into working. > I suspect there will be a long road ahead before my goal is realized. > Thanks for any input to get me going. > > David > > ======================================================== > David Knuth dknuth@intellibot.cc (804) 543-2703 > > ------ > Want more information?
