Well if they call that compatible they need to go back to church as stated
software is purposely designed so a layman can not work on it. Dynagarbage wants 1200.00 for a MB 300.00 for a EXE file Yet I have found a way to retrofit the machine for about 3000.00 with a newer faster and more reliable system that uses off the shelf components and is 15 year newer technology. You can not even install an an A drive or HD without there blessings, which they will be glad to do for enough money. Its no wonder the Asian community is knocking the snot out of American companies when they use business models such as these. 3 months ago I knew not the difference between a steeper or servo, closed loop or open loop. What I have learned so far is who in the industry wants to help you succeed and those that don't care one way or the other.
Sorry for the rant.
