Appolo breaks£1 Ok with 68000 micro Apollo Computers, better known for its small minicomputers has broken the £10000 price barrier with its entrylevel Domain micro. Based on the 68000 microprocessor, the Domain can be used in a LAN. The machine is intended for engineering and scientific applications, according to Apollo's UK managing director, David Howes. Most applications software will centre around CAD, but Apollo is moving towards more office-type programs. The operating system is Apollo's Aegis. A version of UNIX System III will soon be added. Communications with other computers and peripherals are through the Domain network, DSP80 and an X.25 communications gateway. 'We put mainframe capability on a
desktop and integrate it into a network', says Apollo's president, Bill Poduska. 'So you have machines dedicated to individuals rather than people scurrying around a shared mainframe'. Apollo claims that this is the first production system using the 68010 microprocessor. Coupled with a memory management unit, there is a virtual address space of 16 Mbyte to each of 15 concurrent user processes. The basic DN300 comes with 0.5
Two-processor micro pushes into Europe
One-supply arrays boast 2376 gates
Another US designed and built 16-bit microcomputer has been released in Europe. Dynabyte's Monarch is based on the 8086 microprocessor and a Z80B. to handle I/O. The two processors are linked through an architecture unique to the Monarch, says Dynabyte. It lets other 16- or 32-bit chips be fitted at a later stage. Direct memory access is provided to allow high speed transfers of data between discs, memory and tape. It runs independently of both the microprocessors. Operating systems supported by the Monarch include OASIS, MP/M II and MP/M-86. Memory capacity is from 256 kbyte to I Mbyte. Disc storage can be expanded from 19 Mbyte to 76 Mbyte. There is a synchronous port with modem support for bisynchronous communications, using the IBM 2780/3780 protocols and IBM 3270 emulation. An RS-422 port is provided as standard.

Gate arrays with up to 2376 gates have been marketed by Raytheon. Using integrated Schottky logic technology, each device has from 48 to 84 configurable TTL compatible I/Os. They are powered by a 5 V Vcc supply. The array gates and Schottky drivers, which perform most of the logic, are supplied by a 1.8 V Vbb supply and operate at a power dissipation of only 350//W per gate. The standard speed is 2.3 ns. This can be brought down to 1.8 ns, says Raytheon, with 'a proprietary feature'. The arrays are designed for tolerance to radiation and will operate over the temperature range -55°C to +125°C. Program management and custom services are given by Raytheon.

Mbyte of main memory, expandable to 1.5 Mbyte. There is a bit-mapped display too in this £9250 system. The screen management system allows users to overlay views of several processes. A cursor can be moved around the screen using a touch pad a reminder of Apple's Lisa computer. But competition for the Domain is likely to be from traditional scientific mini makers such as IBM and DEC.

by the manufacturer. Developed for use in audio and video equipment, the device has 3 kbyte of ROM and 96 byte of RAM. It can process a command in 2/zs, says Mitsubishi. There are four 8-bit I/O ports as well as a port for I/O expansion. Power consumption is 20 mW at high-speed operation, 100 #W at low speed and 20 #W at standby. The other 8-bit member of the family is the M50790SP, designed for I/O expansion. There are 40 pins for I/O and eight coupling terminals for the M50740SP microcomputer. Together, the two have 72 I/O ports and are priced at ¥1000 for the computer and ¥800 for the expansion. Two 4-bit chips complete the family. Mitsubishi is planning to make 1.5M units in the second half of 1983.
