Eagle Computer: The rise and fall of an early PC clone

When it comes to 80s computer brands, few flew as high as Eagle Computer flew in 1983. The aptly named company was selling 12,000 computers a month and had been doubling sales every quarter under the leadership of a talented CEO. Then Eagle lost its CEO, Dennis Barnhart, in a crashed Ferrari on the day of its IPO, June 8, 1983. In this blog post, we’ll explore the reasons Eagle Computer fell, because there was more to it than just the tragic story involving its CEO.History of Eagle ComputerEagle had been a leading producer of CP/M computers, entering the market somewhat accidentally. They were an offshoot of Audio Visual Labs, who made a product that could double as a general purpose computer. Audio Visual Labs recruited Dennis Barnhart, the vice president of marketing and sales at Commodore, in 1981. Audio Visual Labs spun Eagle off as a separate company soon after, and Barnhart became CEO.Its first IBM compatible computer became a market leader and led to a $37 million IPO based on that computer’s sales and the expected sales of its followups. But on July 30, 1986, just a little over three years later, Eagle Computer went out of business.There’s more to how it got there than the common story involving the Ferrari.Eagle Computer enters the PC clone businessThe Eagle PC 2 featured a high degree of IBM PC compatibility at a good price in an attractive package. It sold well too. Eagle was selling 12,000 units a month at its peak in 1983.When IBM released its IBM PC 5150 in 1981, Eagle decided to pivot from CP/M to MS-DOS. Its first PC, the Eagle 1600, did not attempt 100% compatibility. Like many early PCs, it tried to do at least one thing a little bit better than IBM.The Eagle 1600 received mixed reviews, due in part to its inconsistent compatibility.

Eagle was one of the first companies to understand the market really wanted 100% compatibility, rather than every company trying to one-up IBM in different ways that weren’t compatible with IBM or each other, like the DEC Rainbow and Tandy 2000.Eagle PC 2It wasn’t long before Eagle had an answer in the form of the Eagle PC 2. The Eagle PC 2 was a nearly 100% IBM-compatible desktop computer that worked like an IBM PC while taking up less space on your desk. It didn’t need a fan, so it was quieter than an IBM PC.It also had a nice keyboard garage under the unit to stash your keyboard in to free up desk space when you weren’t using the computer. That saved you from needing to buy a keyboard drawer.Eagle PC Spirit XLEagle had followups waiting in the wings too. One of those was a portable model similar to the Compaq portable. It was basically a portable version of the Eagle PC II, with the same 4.77 MHz 8088 CPU as the PC 2 and the IBM PC. But it had a built-in monochrome monitor and it had one additional expansion slot.I’ve heard people say the Spirit XL didn’t have the build quality of the Compaq Portable. But I’ve also heard it’s much easier to work on than the Compaq Portable.Eagle Turbo XLEagle also had a second desktop model, the Turbo XL. Powered by an 8 MHz 8086 CPU, the Turbo XL ran twice as fast as an IBM PC, while retaining IBM compatibility. The Eagle Turbo XL was one of the first PCs to feature a hardware turbo button on the case, to reduce speed for programs that needed to match the speed of the original IBM PC.Eagle’s three PCs received generally good reviews. The keyboard layout was a bit different from IBM’s, which some reviewers liked and some didn’t. But if you wanted IBM compatibility at a better price, an Eagle was a good choice in 1983.The death of Eagle Computer’s CEO, Dennis BarnhartThe stories of Eagle CEO Dennis Barnhart dying in a red Ferrari 308 GTS on the day of the company’s IPO have taken a life of their own.Eagle Computer’s fortunes changed on June 8, 1983.

That was the day Eagle filed for its initial public offering. The valuation made the CEO and other executives instant multi-millionaires. CEO Dennis Barnhart, whose stock was worth $9 million, died in a car crash that afternoon under somewhat unclear circumstances.Contemporary newspaper accounts of the crash vary. The accounts agree Barnhart and a second person, Sheldon Coughey, owner of a yacht sales company, were riding in Barnhart’s Ferrari 308 GTS near Eagle corporate headquarters. The accounts disagree on which of the two men were driving.There is general agreement the driver took a turn in the road too fast, lost control of the car, the car tore out 20 feet of guardrail, flew into the air, flipped over an embankment, and landed on its roof in a ravine.Barnhart died in the crash. He was only 39 years old. Coughey sustained critical injuries but survived and recovered. Two weeks later, news broke that Barnhart had a blood alcohol level of 0.14 percent at the time of the crash, above the legal standard of 0.10 in California.It may seem odd today that it would be unclear which of the two men was driving. But wearing seat belts was not required by California law until 1986.What really happened in Eagle CEO Dennis Barnhart’s car crashSome accounts I’ve seen grossly oversimplify the situation and the backstory. Over the years, a few people with inside knowledge of the accident have come forward with some additional detail. And it paints a somewhat different story than the common one-line summaries.From what I was able to piece together, Barnhart owned a 1982 Porsche 911 and a 1983 Ferrari 308 GTS. He bought the Ferrari about two months before the IPO and put personalized plates on it that read EAGLE B. Barnhart then started trying to sell the Porsche. Coughey visited Barnhart on July 8, 1983 to see the Porsche. Afterward, Barnhart asked if he wanted to take the Ferrari for a drive.So the accounts that imply or outright say Barnhart celebrated the IPO by shopping for a Ferrari and a yacht, drinking too much, and crashing the Ferrari aren’t accurate.

It was more like he got into a Ferrari with someone who wasn’t used to driving a car with that much power, and he wasn’t in the best condition to instruct him.As for the yacht angle, there isn’t really any indication that Barnhart was shopping for a yacht that day any more than Coughey was shopping for a computer. I would expect Coughey mentioned yachts and Barnhart brought up PCs. That’s what good salespeople do. But they met that day to talk about Barnhart’s 1982 Porsche.The story of Dennis Barnhart often gets repeated as a cautionary tale to young executives of startup companies. Often the story gets some details wrong. If it helps people make different decisions and save lives, that’s a good thing overall. But the stories sometimes include or imply things that didn’t happen.The aftermath of Eagle losing its CEOHis contemporaries remember Barnhart as a talented electrical engineer and a very gifted team builder. The IPO valuation of $37 million was partly based on the company having doubled sales each quarter under Barnhart’s leadership. At the time, Eagle was selling about 12,000 computers per month.The underwriter canceled the IPO, and Eagle conducted a second IPO a week later, on June 15, 1983, lower valuation of $33 million. Many accounts of Eagle say a “much lower” evaluation, but the difference ended up being about $1 per share, or 11 percent.Executive Vice President Ronald Mickwee, a semiconductor industry veteran with 8 years of experience at Synertek, National Semiconductor, and Rockwell International, succeeded Barnhart as CEO.The IBM lawsuitThen, in February 1984, IBM sued, claiming Eagle had violated IBM’s copyright on its BIOS. Like the stories of CEO Dennis Barnhart’s death, the stories of the IBM lawsuit have taken a life of their own.The two companies immediately settled and little or no money changed hands. Eagle did not have to recall any of the units it had already sold, but withdrew its machines from the market until it could replace the BIOS with a non-infringing version. Eagle had reverse engineered the IBM BIOS, and by most public accounts, had not done so in a clean room fashion like other competitors.

This narrative is problematic on two fronts.Eagle Computer did use clean room techniques to implement its BIOSA former Eagle Computer employee, who requested anonymity, told me this is false. Eagle Computer did use clean room techniques, similarly to how other companies did it. Eagle had two teams of programmers. One team wrote the BIOS code and one team had access to the IBM BIOS source code. The team writing code could ask questions to the other team. All questions and responses were vetted and cleansed by attorneys.The challenge was programs like Microsoft Flight Simulator and Lotus 1-2-3 that would call specific memory addresses directly rather than using documented BIOS calls. They would find those addresses with a debugger and through trial and error figure out what the code was doing. Through more trial and error they would ensure they had functionally identical code at those addresses, so the program would work.Based on what this former employee told me, I think Eagle Computer decided it would be less damaging to settle with IBM and take the consequences rather than fight.Eagle Computer had no reason to recall anythingThe same former employee expressed confusion about the assertion I found that Eagle withdrew its unsold PCs from sale. He pointed out that the BIOS chip was a field retrofit, since it was a socketed chip on the motherboard. So all Eagle needed to do was send out replacement chips when the revised BIOS was ready to swap into the machines before returning them to sale.Having swapped BIOS chips in other makes of PCs myself, I can tell you opening the machine and swapping the BIOS chip is no more time consuming than unboxing the PC and repacking it. And it requires three tools: a screwdriver, a chip lifter, and an electrostatic wrist strap.One possibility is that dealers returned computers to Eagle citing the BIOS questions as the reason, but the real reason was they could get IBMs and Compaqs, and returning PCs to Eagle freed up capital and warehouse space to do so.IBM didn’t sue Eagle out of businessThe common story that Eagle’s PC was too good to be true and IBM sued Eagle out of business for making an illegal clone is a gross oversimplification.IBM didn’t sue and win. And that also means IBM didn’t sue Eagle out of business.  The legal action from IBM was one of a series of events that happened prior to Eagle’s demise.
