Abstrakt

The aging DEC PDP-12 computer, serving as the control processor for the Vienna PDS 1010 Microdensitometer, was replaced by a Motorola Exorset 30 system, based on a Motorola 6809 microprocessor. User communication and instrument control are fully implemented in this system; data transmission to a host computer is provided via standard interfaces. The Vienna PDS System (VIPS) software was developed in BASIC and M6809 assembler. It provides efficient user interaction via function keys and argument input in a menu-oriented environment. All parameters can be stored on, and retrieved from, mini-floppy disks, making it possible to set up large scanning tasks. Extensive user information includes continuously updated status and coordinate displays, as well as a real-time graphic display during scanning.
