Remote data acquisition and control system
Three low power PMOS micros keep real time Three low-power single-chip microcomputers that directly drive fluorescent displays, keep real time and provide a wide variety of controller functions have been announced by Rockwell International. The low-drain standby power mode with 'blink' wake-up for both processing and clock time updating of the ~-bit microcomputers offer advantages to applications in security controllers, energy management thermostats, medical and scientific equipment and in handheld applications. Typical power consumption of the PMOS microcomputers is 15 mW at
8- and 16-bit processors mean wide software choice A multiuser computer system for concurrent processing of both 8- and 16-bit programs in a desktop design has been announced by Dynabyte Business Computers. The Monarch offers a wide selection of industrystandard 8-bit and 16-bit operating systems. Monarch can function in these two modes because of its special architecture and interprocessor protocol. The main processor is a 16-bit 8086 with 256k of RAM (expandible to 1 Mbyte). The other processor is Z80B which looks after the I/O. Monarch has nine RS232 ports, one RS422 port and one parallel port. The operating systems which can run onthe machine are CP/M, MP/M II, CP/M-86, MP/M-86, UNIX, OASIS-8, OASIS-16 and Business Basic. The broad range of operating systems gives the user flexibility to choose the operating system that best suits his particular requirements. There are two models of the Monarch, the 6600 and the 6900. Standard pricing of 511 000 and $14 000 give you 19 Mbyte of Winchester storage, and 19 Mbyte of Winchester storage and 17 Mbyte of tape storage, respectively. There are numerous expansion units offering up to a further 57M of Winchester storage. Monarch can accommodate a maximum of 16 users. (Dynabyte

6 . 5 - I I V. The three chips, MM78LS, 79LS and 89LS, are all housed in 40-pin dual packages. The 78LS has 2k ROM, 64 byte of RAM and 31 I/O lines. It will cost $6.60 in quantities of 1000 units. The 79LS has 3k ROM, 128 byte of RAM and 34 I/O lines. The cost will be 58.60. The 89LS has 4k of ROM and the same number of RAM and I/O lines as the 79LS. It will cost $10.30, quantities of 1000.

Multibus, 8086, MSDOS and 20 Mbyte Diskstor-M is a microcomputer system which combines industry standard hardware, Multibus and 8085 or 8086 processors, and industry standard software, CP/M and MS-DOS, with nearly 20 Mbyte of disc storage. The external memory comprises an 18 Mbyte Winchester disc and a 1 Mbyte floppy; the internal memory is 64k or 128k with parity. The Winchester storage is expandible to 36M, the internal RAM to 1024k. The whole system plugs into an eight-slot Multibus and costs around $12 500 for the 808S-based system and $13 500 for the 8086 system.

Emulation between host and remote terminal A microcomputer emulation system which sits between a host computer and the user's terminal has been released by Lock Microsystems. RADIUS (remote accessdevelopment and integration microcomputer system) can be operated in three modes. The transparent mode connects the user terminal directly to the host computer leaving RADIUS completely transparent to the user. Local mode allows the setting of options (baud rate, etc) and RADIUS diagnostics. Utility mode allows the user to carry out hardware and software debugging and integration as well as operating an optional local printer or PROM programmer. The hardware includes a Z80A processor, 64k RAM and four serial I/O ports. There is space allowed for two Mostek in-circuit emulators which operate with the Z80. Software includes the host package which provides down and upload facilities as well as interaction With the emulation systems. It is preconfigured for microcomputers running M/OS-80 or CP/M. The method of connection to the host and terminal is via an RS232 serial interface. (Lock Microsystems

Remote data acquisition and control system A microcomputer-controlled data acquisition and control card manufactured by Intersil is available in the UK from Hawke Electronics. The REMDAC (remote data acquisition and control system) is an evaluation unit which provides the designer with two remote stations, receiver/ transceiver card and an RS232 interface card which links the remote monitoring control stations to the host computer by way of single twisted-pair wires. The purchase price is less than £1000 and Hawke expect the unit to find uses in modular distributed processing systems. (Hawke Electronics Ltd,
