Commodore’s purchase of Amiga, August 14, 1984

On August 14, 1984, Commodore International purchased Amiga Corporation for $27 million, with the expectation of bringing Amiga’s multitasking computer with high-color graphics and sound to market within a year. It took a little longer than that, and it created one of the more interesting might-have-beens of 1980s computing.

The Amiga demo

A little more than a year after Commodore purchased Amiga, the Amiga 1000 hit the market.

Amiga demonstrated a prototype at the January 1984 Consumer Electronics Show (CES) in Chicago, attempting to attract investors, with a 68000-based development system called the Sage IV driving large prototype board stacks substituting for the chipset that did not yet exist in silicon. With no operating system ready, the system demos, including the famous Boing ball demo, ran on bare metal.

Byte magazine reported in April 1984 that Amiga Corporation “is developing a 68000-based home computer with a custom graphics processor. With 128K bytes of RAM and a floppy-disk drive, the computer will reportedly sell for less than $1000 late this year.”

Amiga for sale by summer

Amiga was back at the summer CES from June 5-8, 1984. By then, the company was for sale. Amiga talked to numerous companies, including Sony, HP, Philips, Apple, and Silicon Graphics. Steve Jobs of Apple examined the prototype himself. Silicon Graphics was more impressed than Steve Jobs was, but they only wanted the chipset, not the computer. Amiga also talked to Jack Tramiel, the exiled founder of Commodore and future owner of Atari. Tramiel was interested but every time Amiga made a counteroffer, Tramiel lowered his offer.

Amiga was desperate. Jay Miner, co-founder, lead engineer and architect, took out a second mortgage on his home to keep the company from going bankrupt.

Amiga quickly got caught up in a tangled web.

Amiga’s one-sided deal with Atari

Atari had use for the Amiga technology, but they wanted it cheap. Atari itself was in dire financial straits in the summer of 1984. They offered a harsh 30-day bridge loan for $500,000. If Amiga didn’t repay it within 30 days, Atari would take ownership. Amiga took the deal, meaning they had to find a buyer by the first week of July.

That set in motion a rapid fire sequence of events.

The rapid fire sequence of events behind Commodore’s Amiga purchase

On June 14, 1984, at around 2:30 AM, Amiga secretly met with Commodore and worked out a deal. Commodore would pay $27.1 million for the company and pay off the loan to Atari. The only reason we know about this meeting is the existence of handwritten notes by Commodore treasurer Don Greenbaum that he supplied to Commodore historian Dave McMurtrie.

Two weeks later, on June 29, Amiga CEO David Morse appeared at the Atari office with a check to pay off the $500,000 loan, plus interest. The money came from Commodore.

On July 1, 1984, Jack Tramiel bought Atari. Tramiel had been poaching Commodore engineers since April. Sometime later in July, Commodore sued to try to prevent those engineers from working on a new computer for Atari.

In early August, new Atari VP Leonard Tramiel discovered the agreement between Atari and Amiga, including the cashed check for $500,000. On August 13, Atari counter-sued Commodore and Amiga for breach of contract.

A day later, on August 14, Commodore purchased Amiga. According to Chapter 10 of The Home Computer Wars, by Michael Tomczyk, Commodore’s stock price rose from below $20 to above $30 after the purchase.

Why Commodore wanted Amiga

Commodore was selling more computers than anyone in 1984. The VIC-20 had been the bestselling computer of 1982, while the C-64 was the bestselling computer of 1983 and 1984, on its way to becoming the bestselling computer model of all time. But VIC-20 sales dropped worryingly after 1982, and Commodore was afraid the C-64 would follow a similar path.

But while the C-64 was waiting in the wings before the VIC-20 started to fade, in June 1984 all Commodore had to succeed the C-64 was the Plus/4 disaster. The key engineers behind the C-64 had left. Al Charpentier and Bob Yannes, the designers of the VIC-II and SID chips in the C-64 left in 1983 to found Ensoniq. One of their chips found its way into the Apple IIgs computer. Other longtime Commodore engineers followed Jack Tramiel out the door.

Amiga neatly solved Commodore’s problems. Here was a proven engineering team with a new next-generation design that would be ready to hit the market sometime the following year.

The Amiga 1000 proved the concept but sales were disappointing. It was with 1987’s Amiga 500 and 2000 that Amiga came into its own. But even the Amiga 500 didn’t repeat the C-64’s success.

Commodore couldn’t keep this team together either. The original Amiga team, minus Jay Miner, went on to design the Atari Lynx and the 3DO game consoles.

    “Commodore couldn’t keep this team together either. ”
    Commodore had money problems, so Los Gatos was seen as expensive. Also many of the engineers didn’t want to move to West Chester, Pennsylvania.
    The short shortsightedness of Commodores management certainly didn’t help. Gould wanted to compete with IBM.

      Yes, that is a problem I probably haven’t talked about enough, Commodore lost a lot of engineering talent because they wanted to live in California and didn’t want to move to Pennsylvania.

    According to Brian Bagnall, Lloyd “Red” Taylor and Clive Smith drove Commodore’s acquisition of Amiga. Both saw the Amiga technology as the basis for a low-end C64 successor, which of course was not what the relatively expensive Amiga 1000 was when it eventually launched.

    Red Taylor left Commodore to join Jack Tramiel’s fledgling Tramiel Technology company (soon to acquire Atari) and he was the guy who interested Jack in buying Amiga himself. The rest, of course, is history.

    But what stands out at the start of the Amiga story is the confusion over what the machine was supposed to be and who it was for – console or computer? Low end or high end? Commodore never really resolved that quandary successfully, veering between professional Amiga desktops and cheap mass market wedge computers, never really having a clear roadmap for either market.

      I agree with you, the Amiga was so good at so many things, Commodore didn’t know what to do with it. And they never picked a direction for it and stuck with it. When I had a long conversation a couple of years ago with a longtime Commodore employee, that was something he brought up.

      As for Brian Bagnall, he did his homework. I reviewed several of the chapters in one of his books pre-publication, and he was thorough. And there was nothing wrong with his methodology. If there was something wrong before the books went to press and a reviewer found it, he fixed it. I’ve heard people ask Commodore employees if his books are accurate. Having an inside view into the production of his Amiga Years book, I’m confident they’re as accurate as any of the other computer histories out there, probably somewhat more so.

        Brian Bagnall did sterling work in his series of books on Commodore.

        If there’s one thing missing, I’d like to have heard from the people who are often portrayed as the villains of the Commodore / Amiga story – Irving Gould, Mehdi Ali and Bill Sydnes.

        Gould of course died well before Bagnall started writing, but Ali in particular is an interesting, often demonised figure and he’s never told his version of events. Bagnall actually changed my mind about him.

        According to Brian’s telling, Ali was the driving force behind the A1200 and he made the sensible call to OEM Commodore’s PC line. So yes, Ali made a lot of bad decisions but he was a more nuanced personality than the folk history suggests.

          As far as Ali goes, either Ali or someone claiming to be him reached out to me several years ago. I responded, asking for a chance to tell his side of the story. He never responded. I’ve had several similar requests from other people who worked in the industry in the 80s and 90s and I’ve always gone back and revised those blog posts to include their perspective.

          I don’t know if that person really was Ali or just a prankster. But my door is open. I’m sure Brian’s door is also open, and I can think of several others who would be glad to tell Ali’s side of the story and would do their best to be fair.
