The Intel 8080 ("eighty-eighty") is the second 8-bit microprocessor designed and manufactured by Intel. It first appeared in April 1974 and is an extended and enhanced variant of the earlier 8008 design, although without binary compatibility . [ 3 ]
Intel 8080: 1977: complete board: A trainer type single-board-computer. As recently as 2008, it remained in academic use. [6] As of 2011, the MPT8080 was still available for sale. Rockwell AIM-65: 6502: 1978: complete board: Synertek SYM-1: 6502: 1978: complete board: Intel SDK-85: Intel 8085: 1978: Tesla PMI-80: Intel 8080 clone: 1982 ...
IMSAI VDP-40 desktop computer of 1977-1979. Intel 8085, 32/64KB RAM, 2× FDD 80/160KB, S-100 bus. 2KB monitor ROM, 2KB Video ROM. The IMSAI 8080 is an early microcomputer released in late 1975, based on the Intel 8080 (and later 8085) and S-100 bus. [1] It is a clone of its main competitor, the earlier MITS Altair 8800. The IMSAI is largely ...
Intel SDK-80, assembled Intel SDK-80, unassembled. The 8080 System Design Kit (SDK-80) of 1975 provided a training and prototype vehicle for evaluation of the Intel 8080 microcomputer system (MCS-80), clocked at 2.048 MHz. (The basic 8080 instruction cycle time was 1.95 μs, which was four clock cycles.)
Mirroring the development in the West, where the Intel 8080 was succeeded by the binary compatible Intel 8085 and Zilog Z80 as well as the source compatible Intel 8086, the Soviet Union produced the IM1821VM85A (ИМ1821ВМ85А, actually the CMOS version Intel 80C85), KR1858VM1 (КР1858ВМ1), and K1810VM86 (К1810ВМ86), respectively.

The 4004 was only capable of 60,000 instructions per second, but its successors brought ever-growing speed and power to computers, including the Intel 8008, 8080 (used in many computers using the CP/M operating system), and the 8086/8088 family. (The IBM personal computer (PC) and compatibles use processors that are still backward-compatible ...
The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design.
In April 1974, Intel released the 8080 microprocessor that Roberts felt was powerful enough for his computer kit, but each 8080 chip sold for $360 in small quantities. [24] Roberts felt that the price of a computer kit had to be under $400; to meet this price, he agreed to order 1,000 microprocessors from Intel for $75 each. [25]
