boards is also available. The design of the evaluation board allows it to function as an execution device with assemblers and crossassemblers. This feature provides system designers and programmers with the means to evaluate AmZ8000 execution speed and system throughput with respect to existing programs and designs. Additionally, the AMC96/4016 provides upload and download capability with Advanced Micro Computers' ~mSYS 8/8TM development system. Price for the basic AMC96/4016 evaluation board with monitor 4MHz crystal time base is $975. (Advanced
X Y-1000 Winchester disc subsystem from Xylogics
Mini Winchester Xylogics' XY-1000 Winchester disc subsystem brings the advantages of random access disc storage to users of DEC PDP 11 and LSI 11 systems. It overcomes the major drawback of 8 inch Winchester-type fixed disc technology, that of finding a convenient and efficient method of back-up, by having a 17 Mbyte cartridge tape
option. XY-1000 provides complete operating system and diagnostic transparency, both in disc and tape, and up to 40 Mbyte storage is provided in a standard 19 inch panel space. The system is totally self powered with the capability of expansion to cope with multiple drives. Two controllers provide total redundancy of backup.

A m Z 8 0 0 0 evaluation board Advanced Micro Computers, a subsidiary of Advanced Micro Devices, has introduced the AMC96/4016, an AmZ8000 evaluation board, a fully assembled and tested microprocessor evaluation unit that integrates the necessary onboard software and hardware resources to explore and use the AmZ8000. In its basic configuration, the AMC96/4016 incorporates: • AmZ8000 16-bit microprocessor • two RS232C serial I/O ports • 12 kbytes of EPROM/ROM sockets • system clock • resident monitor One serial I/O port can be configured as either an RS232C or TTY currentloop interface; the other is RS232C only. Two 16-bit counters in an Am8253 counter/timer p~bvide selectable baud rates, up to 9600 baud, for each serial I/O port. The third 16-bit counter in the Am8253 is available for user programs.

AMC96/4016 will also directly control a standard CRT terminal or an optional keyboard with 20-character alphanumeric display that is available as part of the evaluation board. It is physically compatible with SBC80 microcomputer boards and the CPU can be directly addressed through the board's P2 connector. Four options are available on the AMC96/4016. One features a full decoded keyboard and 20-character alphanumeric display assembled on a printed circuit board that edge connects via a ribbon cable to the evaluation board. Another features an EPROM-resident ASCII one-pass line-by-line assembler. A third option is the AMC 95/ 6410 universal prototyping board of the same family form. It provides position for up to 95 ICs, wirewrap pins at connector locations and a plexiglass cover on the wirewrap side for electrical and handling protection. A card enclosure to mount these

Artec shows 5 M H z CPU card A single-board microcomputer that uses Intel's new 8085A-2 microprocessor to permit operation at 5 MHz has been introduced by Artec Electronics, Inc. The S-100 CPU card features a hardware floating point that uses AMD's AM9511 math chip to perform addition operations in 175 ms and multiplication typically in 168 ms. Other features include: •
permanent storage of programs, files and other relevant data in 3kbits of Intel 2708 PROM; 1K of RAM memory for use as a 'scratch pad' • a monitor that tests memory, performs simple debugging operations, and gives program status at any time; this features permits operation without an additional video board • vectored interrupts • switch-selectable I / 0 ports for peripheral device selection • a phantom line that automatically returns the processor to the monitor address A built-in clocking mechanism also allows operation at 2 MHz to accommodate systems with slower memory. The S-100 card is priced at $850 in single quantities. (ARTEC, 605 Old
