MIRAGE challenges UNIX on the 58000
New US releaseeducating ADA The US Department of Commerce has released an educational implementation of the ADA programming language. The software was developed for the Army Tactical Computer Technology Laboratory as an educational and training device by the Courant Institute at New York University. ADA/ed is a translator]interpreter that will compile programs written in ADA and execute them in an interpretive mode. The source tape is an ASCII character set which restricts preparation to 9 track ½-in tape. Recording mode should be identified by specifying density only. (NTIS UK Service Centre,

Portable exerciser will test most floppy drives
MIRAGE challenges UNIX on the 68000
A portable floppy disc drive exerciser, the C Itoh FEX9, has been made available in the UK by Monolith Electronics. The device will test all industry standard drives compatible with the Itoh range of Itoh drives. Read/write tests can be carried out for both single- and double-~ded drives of single density (FM) or double density
A rival to UNIX in the 16-bit operating system stakes has been adopted by MicroAPL. MI RAGE is a multiuser multiasking system that has been written for the 68000 and claimed to
Winchester with virtually no track shifting A Wihchester-based cartridge disc drive has been announced by Century Data Systems. The C8048 is an 8-in drive and has an unformatted capacity of 33 Mbyte (fixed) or 16 Mbyte (removable). The average seek time for the drive is claimed to be 30 ms with a data transfer rate of 1.2 Mbyte/s through standard interfaces SMD and ANSI. Other interfaces can be supplied. Century claim to have virtually eliminated shifts in track positioning due to head nonalignment and thermal effects. Their own 'ventilated spindle' technique has been used which disperses air over the drive's discs.

Exercise your floppy drive with this tester (MFM) types. A test and fault location procedure can be carried out on each drive by means of keyboard and toggle switches: Drive status status is shown by eight LEDs and faults are indicated in code on digital display when switched to error mode. Error history is shown on the display when the FEX9 is set to display mode. (Monolith Electronics

ZX 86 available in UK The ZX 86 microcomputer board manufactured in the US by Zendex Corp. is available in the UK from Giltspur Microsystems. The microcomputer board is hardware and software-compatible with the Intel 86/05 and has many features in common with the 86]12A. Its 8086 processor runs at 5, 8 or 10 MHz and it has 24 programmable lines with sockets for driver/terminator packs. The ZX 86 has an RS232C I/O port which can be expanded:ito two. The board also contains three SBX sockets with 16- and 8-bit word capability. Onboard, the microcomputer has 8k of static RAM and four 28-pin byte-wide sockets to give 16k ROM capacity. It is designed to accept a 128k EPROM. The sockets may also be used for RAM expansion. (Giltspur
