A flexible, low-cost hybrid interface linking a DEC PDP-9 digital computer with an EAI 231 R-V analog computer is described. The interface includes provision for complete mode control of the 231 R-V by the PDP-9, as well as signal selection and potentiometer setting facilities. Data transfer is accomplished by using double-buffered D/A registers with provision for controlling the transfer of data from either the analog or digital side of the interface. In addi tion, provision is made for the updating of several D/A channels simultaneously. A sixteen channel analog multi plexer with a settling-time of less than two microseconds has been designed and is employed with a twelve-bit twenty-microsecond A/D converter for high-speed analog- to-digital data transfer.
