Versatile micro from Intel: Process control, traffic control and point-of-sale processing, are just some of the wide range of applications areas seen by Intel for its single PC board microcomputer module, the 4-43, which is based on the Intel 4040 four-bit processor. Data storage on the 4-43 is provided by the Intel 4002 RAM which can be expanded from 320 x 4 bits up to 2,560 x 4 bits. The program memory, which is separate from the data memory, goes from IK x 8 bits up to 4K x 8 bits. The unit costs £200 and offers 60 different instructions, 24 index registers and up to seven levels of subroutine nesting. Intel believes that one very promising applications area for the 4-43 is in portable traffic light controllers, mainly because the machine is able to match rigid Department of the Environment performance specifications.
