Jameco Electronics 3000 ユーザーズマニュアル

Rabbit Semiconductor was formed expressly to design a a better microprocessor for use in 
small and medium-scale controllers. The first microprocessor was the Rabbit 2000. The 
second microprocessor, now available, is the Rabbit 3000. Rabbit microprocessor design-
ers have had years of experience using Z80, Z180, and HD64180 microprocessors in small 
controllers. The Rabbit shares a similar architecture and a high degree of compatibility 
with these microprocessors, but it is a vast improvement. 

The Rabbit 3000 has been designed in close cooperation with Z-World, Inc., a long-time 
manufacturer of low-cost single-board computers. Z-World’s products are supported by an 
innovative C-language development system (Dynamic C). Z-World is providing the soft-
ware development tools for the Rabbit 3000.

The Rabbit 3000 is easy to use. Hardware and software interfaces are as uncluttered and 
are as foolproof as possible. The Rabbit has outstanding computation speed for a micro-
processor with an 8-bit bus. This is because the Z80-derived instruction set is very com-
pact, and the timing of the memory interface allows higher clock speeds for a given 
memory speed.

Microprocessor hardware and software development is easy for Rabbit users. In-circuit 
emulators are not needed and will not be missed by the Rabbit developer. Software devel-
opment is accomplished by connecting a simple interface cable from a PC serial port to the 
Rabbit-based target system or by performing software development and debugging over a 
network or the Internet using interfaces and tools provided by Rabbit Semiconductor.
