PCs come in 6 European-language versions Two IBM-PC-compatible personal computers have been launched by Applied Digital Data Systems (ADDS) of the USA. The ADDS PC/I and PC/II run under MS-DOS, with versions for UK, French, German, Italian, Spanish and Scandinavian use.

Cassette kit houses 1 Mbyte bubble memory Bubble memory for data recorders, numerical controllers, robotics, and medical instruments has been developed by Intel. The BCK 10-4 comes in the form of a bubble c~ssette kit with 1 M b y t e of removable bubble memory. The bubble cassette's reliability is greater than that of memories that use floppy discs, hard discs or magnetic tape, says Intel, because the solid-state BCK 10-4 has no moving parts and a lower chip count.
The operating tern perature range of the kit is 10-50'~C. The price for 100 units is $461.5. (Intel Corp.

Floating point converter handles 32-bit words A 32-bit floating-point processor has been announced by Advanced Micro Devices. The US firm's A M 2 9 3 4 6 supports IEEE and DEC single-precision formats. It performs float-to-fixed and fixed-tofloat conversions on 32-bit words. The device contains a 24 X 24[)it parallel multiplier. It will perform single-cycle add, subtract and multiply as well as eight-cycle division to 36-bit accuracy, says AMD. Five-cycle division will be to 24-bit accuracy, adds the firm; there may also be four-cycle division by piplining result output with lookup input. (Advanced Micro

is an 8088. Each has 256k of memory, 360k floppy disc storage space and a 300rnm monochrome display. Video output for monochrome, composite colour, RGB-I, light-pen and radio-frequency modulator interfaces are provided as standard, says ADDS. Also included are an 8087 coprocessor, five expansion slots, and built-in diagnostics. The PC/I and PC/II come with GWBASIC. The standard keyboard is detachable. There is an optional keyboard with separate numeric keypad and cursor control. The US price of the PC/I is $2650. The PC/II, with 10 M b y t e Winchester drive, is priced at $4295.

Protocol analysers for development, installation and maintenance of data communications systems have been released by the Industrial Systems Department of Panasonic Industrial UK. The VP-3682P is a portable device for trouble shooting and fault analysis in the field. It has a built-in 64k memory and integral CRT. The unit supports the CCITT X.25 protocol. Data can be displayed in either ASCII or hex. The VP-3682P performs functions such as parity checking, selective triggering and automatic setting. ¸ii~i¸i/¸i¸¸i!!¸¸¸¸i¸¸i¸!¸¸!~!J i¸~¸¸/¸~¸¸!!¸i¸¸i:i~! ~ ~¸¸¸ ~i~ii ~!
