This allows -; pointers to be located relative to the DSA ((Data Structure -; Address) register. -; -; These features make it possible to implement a mailbox style interface, -; where the same piece of code is run to handle I/O for multiple threads -; at once minimizing our need to relocate code. Since the NCR53c700/ -; NCR53c800 series have a unique combination of features, making a -; a standard ingoing/outgoing mailbox system, costly, I've modified it. -; -; - Mailboxes are a mixture of code and data.
