. Designed to be rack-mounted similarly to the later PDP-8 machines, it was smaller in height and ran considerably faster. Launched as "the best small computer in the world", the Nova quickly gained a huge following and made the company flush with cash, although Data General had to defend itself from misappropriation of its trade secrets. With the initial success of the Nova, Data General went public in the fall of 1969. The Nova, like the PDP-8, used a simple accumulator-based architecture. It lacked general registers and the stack-pointer functionality of the more advanced PDP-11

.

Production problems with the Eclipse led to a rash of lawsuits in the late 1970s. Newer versions of the machine were pre-ordered by many of DG's customers, which were never delivered. Many customers sued Data General after more than a year of waiting, charging the company with breach of contract

, while others simply canceled their orders and went elsewhere. The Eclipse was originally intended to replace the Nova outright, evidenced by the fact that the Nova 3 series, released at the same time and utilizing virtually the same internal architecture as the Eclipse, was phased out the next year. Strong demand continued for the Nova series, resulting in the Nova 4, perhaps as a result of the continuing problems with the Eclipse.

), which were coming due for replacement. Data General immediately launched their own 32-bit effort in 1976 to build what they called the "world's best 32-bit machine," known internally as the "Fountainhead Project". When Digital's VAX-11/780 was shipped in February 1978, however, Fountainhead was not yet ready to deliver a machine, due mainly to problems in project management. DG's customers left quickly for the VAX world.

Soon afterwards, Data General launched a hyperactive 32-bit effort based on the Eclipse known as the "Eagle Project". By late 1979, it became clear that Eagle would deliver before Fountainhead, igniting an intense turf war

In the meantime, customers abandoned Data General in droves, driven not only by the delivery problems with the original Eclipse (including very serious quality control and customer service problems), but also the power and versatility of Digital's new VAX line.

(see references), making the MV line the best-documented computer project in recent history. The MV/8000 was a straightforward, 32-bit extension of the Nova-based Eclipse, yet still lacking a hardware stack pointer adopted by most new computers since the late 1960s. It was backwards-compatible with 16-bit Eclipse applications, used the same command-line interpreter as the 16-bit Eclipse, and because it was as advanced in function as VAX/VMS, could execute proprietary 32-bit applications.

.

The MV series came in various iterations, from the MV/2000 (later MV/2500), MV/4000, MV/10000, and ultimately concluded with the MV/60000HA minicomputer. The MV/60000HA was intended to be a High Availability system, with many components duplicated to eliminate the single point of failure. Yet, there were failures among the system's many daughter boards, back-plane, and mid-plane. DG technicians were kept quite busy replacing boards and many blamed poor quality control at the DG factory in Mexico where they were made and refurbished.

In retrospect, the nicely performing MV series was too little, too late. At a time when DG invested its last dollar into the dying minicomputer segment, the microcomputer

s wiped out all 16-bit machines, once DG's best customer segment. While the MV series did stop the erosion of DG's customer base, this now smaller base was no longer large enough to allow DG to develop their next generation. DG had also changed their marketing to focus on direct sales to Fortune 100 companies and thus alienated many resellers.

 (Comprehensive Electronic Office), which included a mail system, a calendar, a folder-based document store, a word processor, a spreadsheet processor, and other assorted tools. All were crude by today's standards but were revolutionary for their time.

Some software development from the early 70s is notable. PLN (created by Robert Nichols) was the host language for a number of DG products, making them easier to develop, enhance, and maintain than macro assembler equivalents. PLN smacked of a micro-subset of PL/1, in sharp contrast to other languages of the time, such as BLISS. The RPG product (shipped in 1976) incorporated a language runtime system implemented as a virtual machine which executed pre-compiled code as sequences of PLN statements and Eclipse commercial instruction routines. The latter provided microcode acceleration of arithmetic and conversion operations for a wide range of now-arcane data types such as overpunch characters. The DG Easy product, a portable application platform developed by Nichols and others from 1975-1979 but never marketed, had roots easily traceable back to the RPG VM created by Stephen Schleimer.

Also notable were several commercial software products developed in the mid to late 1970s in conjunction with the commercial computers. These products were popular with business customers because of their screen design feature and other ease-of-use features. The first product was IDEA (Interactive Data Entry/Access) which consisted of a screen design tool (IFMT), TP Controller (IMON) and a program development language (IFPL). The second was the CS40 line of products which used COBOL and their own ISAM

 data manager. The COBOL variant used included an added screen section. Both of these products were a major departure from the transaction monitors of the day which did not have a screen design tool and used subroutine calls from COBOL to handle the screen. IDEA was identified by some market watchers as a precursor to fourth-generation programming language

s.

The original IDEA ran on RDOS and would support up to 24 users in an RDOS Partition. Each user could use the same or a different program. Eventually IDEA ran on every commercial hardware product from the MicroNova (4 users) to the MV series under AOS/VS, the same IDEA program running all those systems. The CS40 (the first of this line) was a package system which supported four terminal users, each running a different COBOL program. These products also led to the development of a third product, TPMS (Transaction Processing Monitoring System (announced in 1980)) which could capably run a large number of COBOL or PL/I users with a smaller number of processors, a major resource and performance advantage on AOS and AOS/VS systems. TPMS had the same screen design tool as the earlier products. TPMS used defined subroutine calls for screen functions from COBOL or PL/I, which in some users' eyes made it more difficult to use. However, this product was aimed at the professional IS Programmers as were its competitors—IBM’s CICS

Despite the memorable advertisements ("The first computer able to fit inside the IBM PC"), the DG-1 was, however, only a modest success. One problem was the use of 3½" diskettes, which were slightly ahead of their time; popular software titles were not available in 3½" format and this was a serious issue because then-common diskette copy-protection schemes made it difficult for users to copy the software into that format. Additionally, the diskettes used a proprietary formatting scheme not compatible with products from other companies. Although Creative Computing

, it was joked, was often necessary to see the contents of the screen.

Another product killer was the incompatible serial port chip, an Intel 82C51 which was used to conserve power, instead of the 8250 used in the IBM PC. For a portable system, this was a critical flaw — PC programs that used the serial port wouldn't run on the DG-1 due of the non-standard register arrangement within the 82C51.

An updated version of the DG-1 appeared later with a much improved electroluminescent screen. However, the light-producing display could be washed out by bright sunlight. Additionally, the new screen was power hungry and consumed so much power that the battery option was removed, thereby causing the DG-1 to lose its status as a true portable.

Lock-in or No Lock-in?

Throughout the 1980s the computer market had evolved dramatically. Large installations in the past typically ran custom-developed software for a small range of tasks. For instance, IBM

 often delivered machines whose only purpose was to generate accounting data for a single company, running software tailored for that company alone.

By the mid-80s the introduction of new software development methods and the rapid acceptance of the SQL database was changing the way such software was developed. Now developers typically linked together several pieces of existing software, as opposed to developing everything from scratch. In this market the question of which machine was the "best" changed; it was no longer the machine with the best price/performance ratio

 or service contracts, but the one that ran all of the third-party software you intended to use.

This change forced changes on the hardware vendors as well. Formerly almost all computer companies attempted to make their machines different enough that when their customers sought a more powerful machine, it was often cheaper to buy another from the same company. This was known as "vendor lock-in

", which helped guarantee future sales even though the customers detested it.

With the change in software development, combined with new generations of commodity processors that could match the performance of low-end minicomputers, lock-in was no longer working. When forced to make a decision, it was often cheaper for the users to simply throw out all of their existing machinery and buy a microcomputer product instead. If this was not the case "now", it certainly appeared it would be within a generation or two of Moore's Law

In 1988 two company directors put together a report showing that if the company was to continue existing in the future, DG would have to either invest heavily in software to compete with new applications being delivered by IBM and DEC on their machines, or alternately exit the proprietary hardware business entirely.

's report outlined these changes in the marketplace, and suggested that the customer was going to win the fight over lock-in. They also outlined a different solution: instead of trying to compete against the much larger IBM and DEC, they suggested that since the user no longer cared about the hardware as much as software, DG could deliver the best "commodity" machines instead.

"Specifically", the report stated, "DG should examine the Unix

 market, where all of the needed software already exists, and see if DG can provide compelling Unix solutions." Now the customer could run any software they wished as long as it ran on Unix, and by the early 1990s, everything did. As long as DG's machines outperformed the competition, their customers would return because they liked the machines, not because they were forced; lock-in was over.

AViiON was a series of computers from Data General that were the company's main product from the late 1980s until the company's server products were discontinued in 2001. Earlier AViiON models used the Motorola 88000 CPU, but later models moved to an all-Intel solution when Motorola stopped work on...

. The name "AViiON" was a reversed play on the name of DG's first product, Nova, implying "Nova II". In an effort to keep costs down, the AViiON was originally designed and shipped with the Motorola 88000

-based systems, allowing the machines to scale upwards in performance by adding additional processors.

CLARiiON

An important element in all enterprise computer systems is high speed storage. At the time AViiON came to market, commodity hard drives could not offer the sort of performance needed for data center use. DG attacked this problem in the same fashion as the processor issue, by running a large number of drives in parallel. The overall performance was greatly improved and the resulting innovation was marketed originally as the HADA (High Availability Disk Array) and then later as the CLARiiON

 in various capacities, offered a great price/performance and platform flexibility over competing solutions.

The CLARiiON line was marketed not only to AViiON and Data General MV series customers, but also to customers running servers from other vendors such as Sun Microsystems, Hewlett Packard and Silicon Graphics. Data General also embarked on a plan to hire storage sales specialists and to challenge EMC's Symmetrix in the wider market. The success of the CLARiiON product and the challenges faced by the other parts of Data General eventually led to Data General being acquired by EMC in 1999.

Despite Data General betting the AViiON farm on the Motorola 88000

DG quickly responded and introduced new models of the AViiON series based on a true commodity processor, the Intel "x86" series. By this time a number of other vendors, notably Sequent Computer Systems

, a major data storage company, acquired Data General and its assets in 1999. Although details of the acquisition specified that EMC had to take the entire company, and not just the storage line, EMC quickly ended all development and production of DG computer hardware and parts, effectively ending Data General's presence in the segment. The maintenance business was sold to a third party, who also acquired all of DG's remaining hardware components for spare parts sales to old DG customers. The CLARiiON line continues to be a major player in the market today, and is still marketed under that name.
