Hi Chris,

The C5 upgrade if you have enough processor power allows larger file run from memory I have done a bit over 4 MB files, I haven't any code larger than that to run.

To go to C6 you have to go with an White C6 box with NCB card. It will not work with acroloop cards. Call Milltronics with your DIY SBC specs and they will see if C5 software upgrade possible, that's what I did 9 years ago
