Microcomputer Kit

MCS~4 - INTEL'SLOWEST COST MICROCOMPUTER.

IDEAL FOR PROTOTYPE OR LOW VOLUME PRODUCTION.

• Programmable General

Purpose Microcomputer

• 4-Bit Parallel CPU with 46

Instructions

The MCS-4 is a microprogrammable computer set designed for applications such as test systems, peripherals, terminals, billing machines, measuring systems, numeric and process control. The 4004 CPU, 4003 SR, and 4002 RAM are standard building blocks.

The 4008 and 4009 are a pair of inter- face devices which expand the capa- bilities of Intel'sMCS-4 microcomputer set. Now standard Intel PROMs, ROMs and RAMs may be used for the pro- gram memory of the MCS-4.

MCS-4 systems interface easily with switches, keyboards, displays, teletype- writers, printers, readers, A-D con- verters and other popular peripherals.

Asystem built with the MCS-4 micro- computer set can have up to 4K x 8 bit ROM words, 1280 x 4 bit RAM characters and 128 I/O lines without

requiring any interface logic. By adding a few simple gates the MCS-4 can have up to 48 RAM and ROM packages in any combination, and 192 I/O lines.

The MCS-4 has a very powerful in- struction set that allows both binary and decimal arithmetic. It includes conditional branching, jump to sub- routine, and provides for the efficient use of ROM look-up tables by indirect fetching.

The Intel MCS-4 microcomputer set (4002/3/4/8/9 and 4702A) are fabri- cated with Silicon Gate Technology. This low threshold technology allows the design and production of higher performance MaS circuits and provides a higher functional density on a mono- lithic chip than conventional MaS technologies.
