8088 The Intel 8088 ("''eighty-eighty-eight''", also called iAPX 88) microprocessor is a variant of the Intel 8086. Introduced on June 1, 1979, the 8088 has an eight-bit external data bus instead of the 16-bit bus of the 8086. The 16-bit registers and ...

8089 The Intel 8089 input/output coprocessor was available for use with the 8086/8088 central processor. It was announced in May 1979, but the price was not available at that time. It used the same programming technique as 8087 for input/output operat ...

-processors. The component comes in 20-pin DIL package. It was licensed i.e. to NEC and Siemens. If (''Output Enable'') connected to GND, the chip is selected. STB (''Strobe'') is connected to the pin ALE (''Address Latch Enable'') of the processor and takes over the address data from the multiplexed address-/databus. The incoming data is inverted – as opposed to the 8282. The Intel 8283 and I8283 (industrial grade) version was available for US$5.55 and $16.25 in quantities of 100 respectively.8086 Available for industrial environment, Intel Preview Special Issue: 16-Bit Solutions, Intel Corporation, May/June 1980, page 29.
