Motorola adds graphics cards to Versamodule line

National Semiconductor specifies 64k CMOS E2pROM Specifications for a 64k CMOS E2PROM have been announced by US company National Semiconductor. MicroCMOS technology is used to make the NMC98C64. The device's power consumption corresponds to 10 mA in active mode and 100/~A in standby mode, says National Semiconductor. The E2 PROM operates from a 5 V supply. It has a 28-pin Jedec-approved byte-wide pinout. The device's data polling function means that it does not need extra hardware to signal the processor that a write operation is finished.

Lotus Symphony follows best-selling 1-2-3 Business software for desktop and portable micros has been introduced by US firm Lotus Development. The Symphony package uses window management for its word processing, database, spreadsheet and graphics functions. This software, follower of the bestselling Lotus 1-2-3 system, runs on machines with a minimum of 320 kbytes of RAM. The program can run on a single disc drive. Because Symphony resides in user memory, says Lotus, time is saved in not having to transfer programs from discs to user memory. More than one window can be viewed at a time. For example, a spreadsheet and a graph constructed from the data in the spreadsheet can be shown together. Alternatively, unrelated pieces of data can be shown and processed at the same time. The system can be expanded in three ways. Users can bring information from other computers or programs into Symphony. They can use the command language supplied to develop dedicated applications. They can add further Lotus programs to the functions built into the system. The introductory price of Symphony is $695. (Lotus Develop-

The NMC98C64 specification includes a single TTL-level RAM-like write enable. In page mode up to 32 bytes are written per page. The effective writing rate is 300/zs/byte, says National Semiconductor. Address and data latches are contained in the E2PROM. The device has an internal automatic erase, function,

and an optional chip erase function. Write protection has been taken into account too. An onchip timer, and a ready/busy open-drain interrupt output are also present in the specification. (National

Motorola adds graphics cards to Versamodule line

• 128k of dual port RAM • 512 x (horizontal) x 384 [vertical) pixels • 8 colours/pixel • 400 colour shades available for graphic fill • two complete display pages • automatic blink of up to 15 display segments • 56 powerful graphics primitive commands

machine code and installed either as firmware of downloaded into RAM as part of a runtime graphics package. The module defines 56 standard primitives, eg 'draw a rectangle', 'draw a circle'. The host Versabus-compatible system can create display segments by special commands to the board, then place graphics primitives into each display segment. When the display segment is executed by the 68000, the primitives within the segment are interpreted and the graphic figures are put into graphic memory. Up to 64 display segments can be created by the hbst sytem, of which 15 can blink at separate rates set by the user. (Motorola Ltd, European

A set of graphics primitives is defined within firmware. User defined characters may be added using 68000
