He designed and prepared specifications and system drawings, created new software, and modified existing software as necessary for the application of DEC Microvax
and PDP-11 computer-based systems for process control and monitoring.
It is currently installed on IBM-compatible PC computers under MS-DOS, although previous versions existed on IBM-370/158 and Microvax
In 1990, each of over 450 local offices had its own MicroVax
micro-computer on site, as part of a decentralized control system.
Moving a small passive object on a cluster of 4 MicroVax
II workstations connected by a 10 megabit/second Ethernet takes about 12 ms while moving a small process takes about 40 ms.
All electronic components are integrated with one security management software program, the C*CURE System 1 Plus from Sensormatic Electronics Corporation, which resides on a Digital Equipment Corporation MicroVax
computer (located in a secure equipment room).
The program occupies less than 400 kB of memory, requires at least 6 MB of random access memory and 200 MB of hard disk space, and can be run on various computers, including SUN workstations, VAX mainframe clusters, MicroVAX
workstations and IBM-compatible PCs.
INMAGIC Plus operates on several computer platforms, including DEC VAX, MicroVAX
, and IBM PCs and compatibles.
The GIS used and evaluated in this project was Laser-Scan operating on a microVAX
II with a digitizing table, high resolution graphics terminal, and large plotter.
Its DEC MicroVAX
II with a 9-MB internal memory supported 48 active on-line users and 12 background tasks at eight sites around California.
Now, this price range is being taken over by workstations and servers, and the MicroVAX
family is phasing out like a single product.
Bar codes track individual cartons and update inventory records in a warehouse management system, which resides on a MicroVax
3100s in each of the schools serve DEC's PATHWORKS software to the desktop systems, which may be located in computer labs, classrooms, offices and libraries.
