Fault-finding on Intel 8-bit systems Software for finding faults in 8086/ 8088-based systems has been written by Scicon. The suite of modules is called Indigo and is designed to specify which board is faulty. Indigo runs automatically when the system is switched on, or it can be called up by user. The diagnostic program resides in PROM inside the system being tested and Scicon will configure a set of tests to suit the user's configuration. (Scicon

Learn about68000 from Lock Memory, mappedgraphics board An educational computer board for the 68000 16-bit family is available in runs seven attributes
Memory-mapped graphics have been added to the zg0 Eurocard microcomputer system from Pronto Electronics. The PEZg006-38 has increased control over individual characters than its predecessor. Any combination of seven attributes for each character cell can be chosen. The seven are: alphanumeric or (1250m) can be covered. Gateway is transparent to users. The Gateway software runs on a 64 kbyte Apple II but requires an extra network interface card for each network segment that is connected.

the UK from Lock Microsystems. Based on the 68000 microprocessor, the MEX68KECB includes 32 kbyte of RAM arranged as 16k x 16. Firmware is contained in two 8k x 8 ROMs addressed as an 8k x 16 block of memory. Communications is via two P,S232 serial ports with 6850 asynchronous interface adapters and a 14411 baud rate generator giving datarates of 110-9600 baud. Centronix type parallel printer interface is given by the MC68230 and there is an audio cassette interface. Firmware has debug/monitor functions, program entry, assembling, disassembling and I/O.
