It exploits the high quality and use of full upper and lower case characters of your electric typewriter. Users of small computer systems can now expand those systems into applications demanding high quality text, such as word processing. Consisting of an array of coils positioned in the same pattern as the typewriter's keyboard. These coils are wired into an electrical decoding matrix. Designed to operate on voltage available from standard computers, the Dynatyper is easily installed without modification to your typewriter. Adjustments for different key heights are easy. Rochester Data provides interfaces and software for the **TRS-80 Level 1 & 2**, the **Apple II** and also a 6 bit **parallel interface** for general operation with other computers. The same interface board can be modified by jumper selection to eperate in any of the above modes...

It was fully compatible with the Apple II. It, however, had new features: \- a new ROM holding the AppleSoft Basic (floating point version written by Microsoft),\ \- a new auto-start (stored in ROM) for easier start-up and screen editing,\ \- 48 KB RAM,\ \- text modes were the same as the Apple II, but the graphics modes were enhanced, they're the same as the Apple 2e : 16 colours at low resolution and 6 colours at high resolutions. In fact this 6-colour mode was also available on the Apple II since revision 1 of the motherboard. The Apple II+ was sold in Europe as the **Apple IIeuroplus** which could display video in European PAL format, and had ESC sequences for European letters. It was followed by the [Apple 2e](/museum/apple-iie/).
