Wow - it's been a while since I logged in, so I apologize for the delay. I'm usually not hard to get in touch with over the telephone, via email at
motion@abilitysystems.com or from the "Contact" link on our web site at
www.abilitysystems.com. I hope you, or your customer had called.
In case not, the latest Indexer LPT software is 100% backward compatible with your (customer's) hardware, even if you migrate to Windows XP - so none of the wiring will need to change.
If you plan to use Windows 95/98/Me, you might your old Digital Tool software (used to convert G Codes to Indexer LPT commands) will work in a DOS window, though there is only a limited amount of support that we can offer, since we did not write this portion of the software.
Alternately, your customer might consider using our G Code Controller, which runs under Win 95/98/Me and XP.
Manuals are available in .PDF format on request, and I am generally available at (215) 657-4338 between 9:30 AM and 5:00 PM Eastern time to help.
