The Eureka Professional Upgrade adds even more features and power to the Advanced Eureka A4. You can have the Professional installed in your Eureka through any accredited Robotron dealer. The Eureka Professional has a RAM disk, which is exactly the same size as the floppy.
Users can copy an entire floppy disk in one pass.
Since accessing the RAM disk is much faster than accessing the floppy, all disk operations can be made noticeably faster. Disk Utilities now allows copying between the RAM disk and the floppy. The Spelling Checker is now located in FlashROM and is much faster as a result. The Professional Word Processor runs independently of the Eureka Word Processor and Note Taker. User can now operate on very large files, since the Professional Word Processor uses Virtual Memory to manipulate documents.
