Development microprocessor
to call the appropriate subroutines within his program and ensure that FPAL is linked with his program. FPAL features a flexible means to handle arithmetic errors including a userdefined error handler if desired. This library represents a powerful complement to ASM-80 and PL/M 80 by providing 32-bit format add, subtract, multiply and divide; floating-point or integer conversion routines; floatingpoint comparison routines, and negation, absolute value and zero routines. All routines save and restore 8080 registers and are completely compatible with PL/M 80 linkage conventions and the new multitasking executive RMX/80. (Intel Corporation (UK) Ltd.,

The Z6104 is a 4kX1 -bit organized static RAM with access/cycle times of 100/I 70, 150/250, 200/340, 250/380, 300/440 ns. Power requirements are 550, 440, 385, 220 and 220 mW respectively. A single 5 V supply is required and the device is TTL compatible.
Two new MCB boards Ziiog have added two analogue boards to the MCB series. The Z80-AIO is an analogue input/output featuring on the input a signal multiplexer which is strappable for either 32 single ended or 16 differential channels, a programmable gain amplifier, a sample and hold circuit, and a 12-bit A/D converter. On the output are two separate 12-bit A/D converters. Z80-AIB is identical to the AIB except it has no output section. All functions of the module can be programmed by I/O instructions from the Z80. To maintain compatibility with the Z80's 5 V supply, +5 t o -+ 15 V DC/DC converters are available on both boards.

Two new RAM components herald Zilog's entry into the profitable memory business. The Z6116 is a 16kX 1-bit organized dynamic read/write RAM, and comes in a 16-pin package. Thre.e access speeds are available: 150, 200 and 250 ns with cycle times of 375, 375 and 410 ns respectively. In operation, the chip consumes 462mW, and in standby 20 mW. The chip has a 2 ns refresh time, interfaces directly with TTL logic, and can withstand a 10% fluctuation in power supplies (+12 V,
-12v,+ sv).
Development system The Z80-PDS is a compact program development system which sells in basic form for £2 000. The standard system consists of a floppy disc drive with up to 300 kbytes of online data storage, internal memory of 3 kbytes of PROM and 16 kbytes of RAM, and serial I/O with RS-232 or strappable current loop interface. The system is intended for the smaller user and complements the Z80 Universal Development System (UDS) which costs £6200 and includes hardware development tools, required by only a few engineers. The Z80-PDS can be used on its own or as a satellite to the UDS. The serial I/O feature allows the correction of any standard CRT or hardcopy terminal at rates from 110 baud to 19.2 kbaud. The ZSO-PDS may also connect directly to an optional Zitog keyboard and TV monitor or some commercial TV monitors by using the £345 Z80-VDB (video display board). There are several optional system modules including the: Z80-PPB (PROM programmer board); Z80lOB (input/output board); ZS0-SIB
(serial I/O board); Z80-VDB (video display board); Z80-MON (video monitor); and Z80-KRD (keyboard module). The last two modules are for use with the Z80-VDB. Software for the Z80-PDS, similar to that presently being used in both the Z80 development system and Z80 microcomputer family, includes discresident operating system, editor, assembler, debugger and file handling utilities. The customer has a choice of two assemblers depending on the amount of memory. As an example, a 2633 line program (approximately 5 kbyte) took 3 rain 11 s to compile on a 48k development system with two discs; 3 min 18 s to compile on a 32k disc development system, and 19 rain 22 s to compile on a basic Z80-PDS with 16k of memory. A paper-tape based system would take about 150 min to compile such a program. For purchasers of OEM boards, the PDS is ideal for software development. It is believed that the PDS will form part of several business-oriented systems and find applications in word processing. (Zilog UK Ltd, Nicholson

Single bits GIM have released a new single-bit microprocessor which executes Boo-
lean logic operations and can be used as a sequence timer and controller. The device has a 16-level stack for handling multiterm functions, plus lkX8-bit ROM and 128 bits of RAM. The chip comes in a 40-pin package, 30 pins of which are available as latched inputs or outputs, and it requires + 5 V and + 12 V supplies.
Development microprocessor A complementary development microprocessor to GIM's PIC 1650 device has been developed. This unit (PIC 1664) has pins which accessto external PROM so that programs can be developed on it before they are permanently committed to the 1650's mask programmed ROM. (General Instrument
