DYNATYPER Here is the sale brochure of the Dynatyper, a strange and obscure printing device launched in 1980: Dynatyper is a new typewriter interface system designed to generate hard copy directly from computer output through any electric typewriter. 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...

The Apple IIc Plus unit was a direct response to the Laser 128EX/2.

Apple retrofitted the IIc design to try to compete with Video Technology's high-speed Apple II clone. The retrofitting is evident in the design of the motherboard. The motherboard runs at 1Mhz, unlike the Laser 128EX/2. In order to run its programs faster, Apple used a 4Mhz 65C02 with 8k of high speed SRAM cache and licensed the accelerator design from Zip Technologies (makers of the ZipChip accelerator for the IIe and IIc). They built an accelerator into a 1Mhz motherboard rather than designing a faster motherboard from scratch.

The designers of the Apple IIc Plus originally wanted to make a portable IIGS. Apple's management, bent on promoting the Mac, balked at the idea. At the same time, the Laser 128EX/2 made a quick design cycle mandatory. The result was an updated IIc.

The Apple IIc Plus was the finest Apple 8-bit computer ever built, but due to a lack of marketing, the apparent backward step in technology compared to the 16-bit Apple IIGS, and the aggressive sales of the Laser 128EX/2, the IIc Plus also was to be the most short-lived of the Apple II models.

Thanks to Steve and his site for the picture.

Chris Brown adds:
I used this computer for a long time. My parents bought it for us as our very first family computer. I do remember that the "foreward slash" button (next to the reset button) on the IIc+ had a different function than on the IIc. On the IIC+ it allowed you to switch between Dvoark and Standard keyboard layouts without any other software - it was a hardware switch.
Also, the IIc+ came with a keycode that, I guess, disabled the Zip Chip accelerator. While the IIc+ was compatible with much of the IIe and II+ software, oftentimes software programmed for earlier systems would be "hyperactive" on the fast new processor, and was virtually unusable unless it was slowed down. The keycode for a standard, full speed reset was open apple - control - reset. If you wanted "half speed" you hit open apple - control - esc -reset.
Also, the power supply on the IIc+ was internal. This caused heat problems which the IIc did not have, and occasionally (I have heard) caused problems. But I used it for 7 years without any problems whatsoever. A flawless machine.
