When Exxon Wanted To Be a Personal Computing Revolutionary

An anonymous reader writes with this story about Exxon's early involvement with consumer computers. "This weekend is the anniversary of the release of the Apple IIc, the company's fourth personal computer iteration and its first attempt at creating a portable computer. In 1981, Apple's leading competitor in the world of consumer ('novice') computer users was IBM, but the market was about to experience a deluge of also-rans and other silent partners in PC history, including the multinational descendant of Standard Oil, Exxon. The oil giant had been quietly cultivating a position in the microprocessor industry since the mid-1970s via the rogue Intel engineer usually credited with developing the very first commercial microprocessor, Federico Faggin, and his startup Zilog. Faggin had ditched Intel in 1974, after developing the 4004 four-bit CPU and its eight-bit successor, the 8008. As recounted in Datapoint: The Lost Story of the Texans Who Invented the Personal Computer, Faggin was upset about Intel's new requirement that employees had to arrive by eight in the morning, while he usually worked nights. Soon after leaving Intel and forming Zilog, Faggin was approached by Exxon Enterprises, the investment arm of Exxon, which began funding Zilog in 1975."

      Of course adding extra peripherals limits that portability - just like now - but the most common hardware was built in and self contained.

      The only big downside for portability the Apple //c had was that the display was an option, and you could choose between the attachable LCD or an external black and white (well, green) CRT that was much cheaper. The CRT was not very portable, although I remember being able to carry it by the built in handle as a child, but it was just as fragile as any other CRT at the time.

It was pin compatible with a real Z80, but when the M1 pin of the real Z80 inside indicated that an instruction opcode was being read, the data bus was routed though a ROM that translated the bits so the code from the program ROM couldn't run on a 'naked' Z80.

Developing for them is also much more involved and particularly for high reliability applications it can be harder to audit the code and guarantee safe operation.
