For those of you who don’t know Mirage, it is a real-time, multi-user, multi-tasking networking 08 specifically developed for the 68000 CPU and, fike the Challenger, it is British. The first Mirage-based Challengers were shipped early in 1986 and Marston Spurtier became the Distributor of Mirage Language processors and software for Gemini Challenger dealers At refinements have Deen Bade both to Mirage (with & new version due for release as Scorpio News nite the Streecs} and the Challenger when running Mirage, the combinetion 13 (Nick Believes) formidable and there is no competition ae to price/performance

Marston Spurrier’s business is now wholly based on Challenger systems sales and Gevelopment of new software and utilities for Mirage. For example, the latest product is a Mirage software driver to read Gemini CP/M (80, 86, 6Bk) disks. Rick is elso s consultent to Sahare Software (the Mirage sales organitetion) aesisting in porting of existing applicarions co the Mirage eovironment One of the projects he hae been involved in will recult in the publication in January Leer of an integrated Word-Processor, Spreadsheet with colour graphics, document formatter with indexing and table of contents generator, software printer. font generator and print package to drive laser printers with voftware fonts rather than the inordinacely expensive ROM fonts. This is fully multi-user and will retail at (595 true gulti-user software at a PC price

‘A Review of the Newburn Opto-input Board by M. Black

For our particular application, we needed to Interface a variety of different Voltages to the @0-8U5 We saw an advert from Newburn Eleccronies for thelr NEO71 opro-input board Te seemed just what we needed av the board ts self-contained, and unlike the Maas boord does not cequire the Gemini GMa16 I/O board todrive ie (therefore less BUS slots are required) We ordered a board with plug-in sodules for 8 of each 12Y, 24v, SOV and 110V sensitivity We also Srdered the industrial Kiippon termination.

We ceceived the board within a few days On inspection, the board seemed well ade with a comprehensive manual. It’s nice to see that 0-BUS manufacturers now include board-ejeccors as standard, this saves many grazed knuckles

We set the board address to Hex $40 using the on-board Dil-svitch and plugged the board into the rack We used (0 way ribbon cable to connect the board to the Kiippon block” The K1zppon black mounted easily on the rear of the rack sing standard Flippon rai

Connecting a suitable voltage to the correct Klippon terminals, lit the corresponding LED on the board. We found it very handy being able to see the State of atl inputs using the LEDs

Programming of the board was carried out using Turbo Pascal _ This was very simple as all inputs are read from 4 ports, inthis case Hex $40 to Hex $43 Each bit of the port corresponds to one input.

In conclusion, we found the board ideal for our application. Gone are the days of birds nest’ wiring and resistive dividers hanging from the rear of connectors Stc. Real inputs can be easily connected using the Klippon termination rail This gave us the professional finich we required:
