NEW PRODUCTS FEATURE PRODUCT COMPUTER ON A CHIP Intel has introduced an integrated CPU complete with a 4-bit parallel adder, sixteen 4-bit registers, an accumula- tor and a push-down stack on one chip. It's one of a family of four new ICs which comprise the MCS-4 micro computer system--the first system to bring the power and flexibility of a dedicated general-purpose computer at low cost in as few as two dual in-line packages. MSC-4 systems provide complete computing and con- trol functions for test systems, data terminals, billing machines, measuring systems, numeric control systems and process control systems. The heart of any MSC-4 system is a Type 4004 CPU, which includes a set of 45 instructions. Adding one or more Type 4001 ROMs for program storage and data tables gives a fully functioning micro-programmed com- puter. Add Type 4002 RAMs for read-write memory and Type 4003 registers to expand the output ports. Using no circuitry other than ICs from this family of four, a system with 4096 8-bit bytes of ROM storage and 5120 bits of RAM storage can be created. For rapid turn-around or only a few systems, Intel's erasable and re-programmable ROM, Type 1701, may be substituted for the Type 4001 mask-programmed ROM. MCS-4 systems interface easily with switches, key- boards, displays, teletypewriters, printers, readers, A-D converters and other popular peripherals.

The age of the affordable computer. MITS announces the dawning of the Altair 8800 Computer. A lot of brain power at a price that's bound to create love and understanding. To say nothing of excitement. The Altair 8800 uses a parallel, 8-bit processor (the Intel 8080) with a 16-bit address. It has 78 basic machine instructions with variances over 200 instructions. It can directly address up to 65K bytes of memory and it is fast. Very fast. The Altair 8800's basic instruction cycle time is 2 microseconds. Combine this speed and power with Altair's flexibility (it can directly address 256 input and 256 output devices) and you have a computer that's competitive with most mini's on the market today. The basic Altair 8800 Computer includes the CPU, front panel control board, front panel lights and switches, power supply (enough to power any additional cards), and expander board (with room for 3 extra cards) all enclosed in a handsome, alum- inum case. Up to 16 cards can be added inside the main case. Options now available include 4K dynamic mem- ory cards, 1K static memory cards, parallel I/O cards, three serial I/O cards (TTL, R232, and TTY), octal to binary computer terminal, 32 character alpha-numeric display terminal, ASCII keyboard, audio tape interface, 4 channel storage scope (for testing), and expander cards. Options under development include a floppy disc system, CRT terminal, line printer, floating point processor, vectored interrupt (8 levels), PROM programmer, direct memory access controller and much more.
