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 <sarcastic grin> 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?
