In 1981, the company unveiled the DN100 workstation, which used the Motorola 68000 microprocessor. Apollo workstations ran Aegis (later renamed Domain/OS), a proprietary operating system with a POSIX-compliant Unix alternative frontend. Apollo's networking was particularly elegant, among the first to allow demand paging over the network, and allowing a degree of network transparency and low sysadmin-to-machine ratio that is still unmatched. 1981 (MCMLXXXI) was a common year starting on Thursday of the Gregorian calendar. ...

From 1980 to 1987, Apollo was the largest manufacturer of network workstations. At the end of 1987, it was third in market share after Digital Equipment Corporation and Sun Microsystems, but ahead of Hewlett-Packard and IBM. Apollo's largest customers were Mentor Graphics (electronic design), General Motors, Ford, Chrysler, and Boeing (mechanical design). 1980 (MCMLXXX) was a leap year starting on Tuesday. ... 1987 (MCMLXXXVII) was a common year starting on Thursday of the Gregorian calendar. ... 1987 (MCMLXXXVII) was a common year starting on Thursday of the Gregorian calendar. ...

Decline and Fall

Despite beginning two years earlier than Sun Microsystems, Apollo did not maintain the lead that should have been afforded by that two-year advantage. Like many which initially have a clear field when entering the market, the company seems to have assumed that it could dictate terms to the market, rather than finding the best path. Thus the Aegis/Domain operating system, while always Unix-like, failed to pick up on the trend towards Unix until about 1987, with Domain version 10. This release was larger and significantly slower than previous ones, a classic case of being late with the wrong product. Competitors were also gaining ground in the area of graphics and windowing systems, particularly with the trend to Open Systems and the X Window System. KDE 3. ...


In the hardware area, Apollo's vertical structure, producing much of its own hardware and software, made innovation slow and expensive compared to Sun, which bought on the open market. The company was also involved in two technological transitions. It decided to abandon its proprietary data bus architecture in favor of IBM's AT-bus, as used in the second generation of IBM PC's, and was simultaneously embracing RISC technology moving towards high-end processors, eventually producing the PRISM line. Industry Standard Architecture (in practice almost always shortened to ISA) is a computer bus standard for IBM compatible computers. ... Reduced Instruction Set Computer (RISC), is a microprocessor CPU design philosophy that favors a smaller and simpler set of instructions that all take about the same amount of time to execute. ...


The workstation industry in general experienced hard times in the second half of the 1980's, as PC's began making inroads on their customer base. Apollo was entering a financial squeeze. The company's management style changed in 1985 with the hiring of Thomas Vanderslice as President and CEO. Coming from large companies GE and GTE he brought cost-cutting, dress codes etc. which caused many defections among the hardware and software engineers. Ge or GE may stand for: Ge, a letter of Cyrillic alphabet Gaia, (Ge) short form Ge is also an American Indian tribe from Eastern and Southern Amazon General Electric (GE). ...

Between 1988 and 1989, the company incurred huge losses in currency speculation, apparently due to the trading activities of one individual. Not long afterwards Apollo agreed to be bought by Hewlett-Packard.

The Apollo Guidance Computer (AGC) was the first recognizably modern embedded system, used in real-time by astronaut pilots to collect and provide flight information, and to automatically control all of the navigational functions of the Apollo spacecraft.
The computer's RAM was magnetic core memory (4K words) and ROM was implemented as core rope memory (32K words).
These errors automatically aborted the computer's current task, but the frequency of radar data ensured that the abort signals were being sent at too great a rate for the CPU to cope [5].
