NDC+ protocol (NCR Direct Connection) documentation? [closed]

Question

NDC is an ATM software application protocol from NCR corporation. Anyone can tell me how to get documentation for NDC / NDC+ / Advanced NDC? Cause i want to develop simulators and application (both ATM and the Host) based on it.
Thanks.

NDC Protocols are not open. If your company has got a NCR ATM, you can find the documentation on ATM CDs. – Morry
