Commodore's philosophy: Computer PET 2001

This is an eight-page A5 booklet produced for the launch of the Commodore PET in the UK, a machine which made its debut at the Chicago Consumer Electronics Show in January 1977, months before its contemporaries the TRS-80 and Apple II. 

However it didn't start shipping to the public in serious numbers until towards the end of that year, and didn't actually make it to the UK until 1978.

Shown here under its original name of the PET 2001, the machine was based on the 6502 processor and came with either 4K or 8K RAM, which was expandable up to 32K, although later on Commodore took to punching out the expansion sockets so that cheaper models couldn't be bought and upgraded using third-party memory.

[picture: pet2001_leaflet.jpg|Photos of the prototype PET in action, from the sales leaflet, 1978]The name PET was a made-up backronym of Personal Electronic Transactor - or less charitably Peddle's Ego Trip, after its designer Chuck Peddle - and was influenced by the Pet Rock fad of the mid 1970s created by George C.  Coakley[source: "Newsprint", PCW, March 1984, p. 18][source: HCW, p. 32]. 

The number 2001 was chosen simply because that was familiar to the public via the film 2001 - A Space Odyssey, and so sounded suitably space-age.

[extra: comm_US5M.jpg|A Commodore US*5M, showing the same sort of keys as used on the original 2001 PET - see below]There was an 8K ROM present, containing a version of the Microsoft BASIC which was becoming something of a standard, along with a 4K operating system, also in ROM. 

The early PETs used "chicklet" keys that were essentially left-overs from Commodore's calculators.  Although these were arranged in standard QWERTY, their positions were slightly non-standard, with the keyboard being arranged in a strict grid. 

The small-sized keyboard did however mean that the PET could also fit in an in-built cassette player for program storage.

Commodore released updated versions of the PET the following year which had a proper full-sized keyboard and which moved the cassette to an outboard unit - the one shown in this leaflet as the "2nd cassette deck".

It also came with a built-in 9" monitor - the prototypes used a stripped-out Sanyo TV tube from a local electronics shop as they were the cheapest available - whereas production models used Amperex tubes, amongst others. 

The product photos inside the leaflet showing screenshots of the PET in action also show this prototype, as the monitor housing has smoothly-curved lines.

From Byte, October 1977]The production version of the PET had to do away with the futuristic lines of the plastic-moulded case, in favour of a straight-edged metal version, as this was much easier and cheaper to produce. 

The metal case was made by Commodore's office furniture division in Ontario - the largest manufacturer of budget metal office furniture in Canada[source: HCW, p. 68].

At launch, the PET 2001 retailed for $595, for the 4K version, and $795 for the 8K - that's about [[540|1977]] in [[now]]. 

First appearances seemed positive, with Byte magazine writing:

<p class="ref">The PET is an excellent example of the true appliance computer: a neat, self-contained graphics-oriented package designed for the mass market as well as for the serious experimenter.


<h3>Commodore's Canadian Connection</h3>

The reason for Commodore's Canadian connection dated back to Commodore's origins in the 1950s.

After being liberated from the Ahlem labour camp, which itself followed incarceration at Auschwitz, Polish national Tramiel - real name Idek (or sometimes Jacek) Trzmiel - relocated to the US.

He joined the US Army and was posted to Fort Dix, where he learnt how to repair the army's office machinery.  He used this experience after leaving the army to open up a typewriter repair business in New York's Bronx, where he also worked as a part-time taxi driver.

Tramiel then brokered a deal with a Czechoslovakian typewriter business to assemble their typewriters in the US. 

However, as Czechoslovakia was part of the Communist Bloc, the components had to be imported indirectly via a new Commodore company in Toronto, Canada.

By 1962, Tramiel's company was big enough to float as Commodore Business Machines, Canada. 

However, a financing scandal involving Tramiel's first chairman - C Powell Morgan - led to Canadian financier Ivring Gould stepping in to buy a large stake in the company, in order to secure its future.

[extra: commodore_c110|The Commodore C110 - a re-branded Bowmar - launched in 1971|200|left]Tramiel later visited Japan in order to understand how the Japanese were managing to undercut Commodore's mechanical adding machine business. 

It was here that he witnessed the new electronic desk calculators which were about to destroy Commodore's existing business and switched the company over, introducing its first electronic pocket calculator - a re-branded Bowmar - in 1971.

When Texas Instruments kicked off the Calculator Wars of the mid-1970s, by selling complete calculators for less than the cost of the component parts it sold to everyone else, Commodore responded by purchasing struggling calculator chip supplier MOS Technology, with the help of a $3 million loan personally guaranteed by Gould[source: "A living legend", Commodore Computing, March 1984].

MOS Technology was also producing the 6502 processor, and the KIM-1 single-board computer to go with it. The company also included the 6502's designer Chuck Peddle, who was instrumental in persuading Jack Tramiel that the next step in Commodore's evolution should be a microcomputer.

This would become the PET - sometimes known as Peddle's Ego Trip - which was essentially the KIM-1 in a case with a keyboard, monitor and a bit more memory.

Commodore also went on to buy CMOS chip maker Frontier and LCD manufacturer MDSI.
