Hi, I am Tech Michael Good morning.
I sympathize with you. It has happened to me with my robotic files as well ;-(
In this particular situation there is no way to convert those files for use in the now unit. The reason is the format is not compatible with today's data accessing methods. The only way to do that, would require you to build a a special device with correct porting and have an IC burned to make those transfers readable by the new system.
Its a lot of work, and unfortunately they dont sell the equipment for that any longer. They used to have that stuff available to us techs but no longer lol.
I wish I had better news for you on this I really do.
But if you are electronically skilled, I can look to see if I can find the parts so you can build this device?
You would need a good working knowledge of electronics and the tools for this task.
In any case, I will stick with you until this is complete.
Please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you and have a great day!
