I have an older matsuura vertical mill. It's a MC-710V. It has a Matsuura controller. The number on the controller is EN4-00384A. It only holds 9000 or 10000km, which is a big pain. Can I upgrade my memory. Or do I have to upgrade the controls and drives to do this or can I just add chips. I have some pics of the boards if this helps.

Alternatively I do have a Decitek DNC box, behind the card reader and cables but I only know how to send programs to the controller. I can't find the paper owrk and need some help on using a DNC box to drip feed programs. Any advice would be appreciated. Thanks.
