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...

Marcio (Brazil) Saturday 20th September 2003 The Z80 processor was actually used to manage advanced keyboard functions, like type ahead buffer, hot key macros, etc. In order to use CP/M it was necessary to install a separate board in one of the slots. With this board you had three CPUs (one 65C02 and two Z80) in one micro, not very common on those days.

TK-3000 was the local version of Apple IIe manufactured in Brazil.

There were two models:
• The full size one, very similar to American Apples
• A "Compact" one, which included following on-board devices:
- Floppy disk controller,
- Parallel and serial interfaces
- A 256Kb memory module.

Despite Microdigital efforts, TK-3000 lost the battle wih MSX models, mainly due to lack of software in Brazil.


Contributors: Roberto Isiri (info & pix)

About the Brazilian regulation that allowed local manufacturers to copy US and U.K. computers, Roberto clarifies:
The "clones" made in Brazil during the 80's actually were licensed products.
Although Brazilian Government forced us to manufacture our hardware, the technology and some main components such as processors and printer heads were imported from the American and European manufacturers.
By that time, we had no user assembled (w/o brand) PC's. This situation changed in early 90's, when the laws became softer and the Chinese boards and cheap refurbished components arrived. It was the end of locally branded computers...

but Ernesto Hublard corrects:
Most of the Brazilian manufacturers copied US and UK computers without neither licence nor agreement from the brands they copied. Sinclair sued Microdigital for this reason. Another company made an Apple Macintosh clone without any agreement from Apple.

Gabriel Graça replies: Ernesto forgets that the clones were not illegal under brazilian law. The WTO did not yet exist, and foreign computer companies were barred from Brazil. The only foreign company that obtained a licence to sell in Brazil was HP (they sold the HP85B). Apple only managed to stop the production of the Mac clone because the US threatened Brazil with trade sanctions.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
