Until December 1986, 1,000,000 Commodore 64s were sold in Germany. On this occasion, Commodore Buromaschinen GmbH (Commodore's German subsidiary) released a limited edition of a golden C64, serial numbers 1,000,000 to 1,000,199 [6], which was presented to the public in the BMW museum in Germany Commodore had rented for this event. One of these machines was donated to the German magazine \"64'er\" (serial number 1,000,058).

There are thus 3 hidden RAM memory blocks (in blue) which can replace, on request, the corresponding ROM blocks. But these block commutations can only be controlled through assembly language by advanced programmers. Any block switching error results in an immediate and unrecoverable system crash.

THE COMMODORE 64 COULD BE THE MICROCOMPUTER INDUSTRY'S OUTSTANDING NEW PRODUCT INTRODUCTION SINCE THE BIRTH OF THIS INDUSTRY. (Shearson / American Express)

The value of a computer is determined by what it can do. What it can do is largely determined by its memory.
The Commodore 64's basic RAM is 64K. This amount of power is unusual in a micro at any price.
At $595 it is astonishing.
Compared with an Apple II+, for instance, the Commodore 64 offers 33% more power and considerably les than 50% of the cost.
Compared with anything else, it's even more impressive...

The Q.D.D. is however not more than an advanced tape recorder using a magnetic tape, and the delay to access a specific file still remains higher than with a normal disk drive.

I have done so much with it. I used it live on stage with the MusicPort keyboard attached, I have used it as a MIDI sequencer, sampler / drum machine (Datel Sampler 64 hardware), database (The Consultant), editor for posters for my band (Tech Sketch lightpen and Wico trackball), & telecommunications.

Today, I have a very, very small collection of old Commodore computers. It's my personal contribution to those machines, since I had such a good time with them. My collections includes an Amiga 1200 (running OS 3.5 and NetBSD 3.1 and connected to my LAN), an Amiga 500 (with an external MIDI interface), a C128D (european version) and two C64s. I even have a \"RetroReplay\" and a \"MMC64\" cartridge for the C64/C128 systems along with the RRNet ethernet adapter, so I can do some simple telnet and very, very limited web browsing (utilizing ContikiOS by Adam Dunkels). Especially the fact that after more than 20 years beyond its initial release there is (amongst other cool hardware add-ons) something like an ethernet adapter available for the good ol' \"breadbin\", makes this machine a real legend!

I know that Speccy, Apple II and BBC users do feel the same towards \"their\" machines, but for me Commodore and most of their systems (execpt, maybe, the infamous C16/116/Plus 4 computers - sorry Mr. Herd) still count as the #1 computer company / computer products of all times.

There is allegedly a program out there somewhere which allows the C-64 to interface with a Ham Radio and act as a Morse Code/Text Coder/Decoder. In short, Morse code signals would be translated to text on the screen, and one could reply by typing out text, which would be sent to the HAM Radio as morse code!

I also remember that this was the very first computer I ever programmed on, and I am still quite impressed with its capabilities. From a 3-D Pac-man clone to a game with actual speech in its loading screen, this little unit always amazes me. It also has amazing compatibility with Atari 2600 and 7800 joysticks, and limited compatibility with the Sega Genesis controller.

My current set up for my C-64 consists of a C-64, a shoebox full of software, a Commodore 1702 color monitor (can even be hooked up to any standard A/V source, mono sound), dual VIC 1541 5.25\" floppy drives, an Epyx Fast Load Cartridge, a Modem 64 to swap with the Fast Load, two Atari 2600 joysticks, and a home-brew buffer for the joystick ports made in a standard Radio Shack project box." }, { "author": "Juan Jose Velez (Mexico)", "date": "Thursday 28th June 2007", "text": "This model of Commodore computer, as the C16, was also distributed in Mexico by a company called Sigma.

Years ago.. when the 64 was still a hot number, I purchased a 1581 disk drive from a friend of mine who ran a local BBS but was shutting it down.

For a monitor, we used a TV set. We later got a 5.25 inch floppy drive and a word processing program that would let you type up to 7 pages of text (any more and the machine would slow down and freeze). Our first one (which you have pictured) did die, and we replaced it with a slightly redesigned model that was more lower and more streamlined sometime in 1988-1989. For games we had \"Lemonade Stand\" and \"Oregon Trail\". We also got a magazine that had programs printed out in it so that you could type them into the computer manually.

The commodore 64 is, along with the Apple II and the Atari XL computers, the most famous home computer. According to the 2001 edition of Guinness book of records, the C64 was the most "prolific computing device ever manufactured". During its production run from 1982 to... 1993, about 30 million (!) units were sold. To put this number in perspective, that's more than all the Macintoshes in the world.

The C64 was an up-market version of the VIC-20. A wide range of software packages, games and programming languages was available for this machine which was itself available practically anywhere from a toyshop to a business supplier.

Superficially, the C64 closely resembled the VIC-20. It had the same casing, an identical keyboard configuration and virtually the same interfaces and sockets. But the apparent similarity belies some fundamental differences: a MOS 6510 processor and 64 KB of RAM which was quite unusually large at the time for a model of this price range. The C64 also had the ability to recognise user-established priorities by which 'sprites' (or movable blocks) could move independently of displayed text/graphics, enabling the creation of graphics with up to 8 layers.

Music synthesis was performed by a special sound interface chip. Sound envelope could be controlled on all three voices on a full nine octave of each. It was one of the first computers to offer both a high quality sound chip and graphic resolution with many colors and sprites.

A great range of peripherals was developed for this computer and it can also use several of the Vic 20 peripherals.

Several versions of the Commodore 64 were launched :
The first one, C64-1, used the VIC 20 case and was to be quickly replaced with the C64-2 (pictured) which used the famous brown case, and later by the C64-3 with small cosmetic changes in the keyboard.
A special version called Educator 64 or PET64 or CBM 4064 was proposed for schools and uses the PET case.
Commodore produced the first generation of C64s until May 1986, then it was discontinued and they introduced the C64C. According to the 64'er magazine, this version has been planned since the Hannover Fair in 1985, but as the old version sold so well during Christmas '85, its release date was delayed.
Then appeared the C64 "Aldi" (1987, only in Germany) and the C64G (1989). They were virtually same machines, this time with the new, short motherboard. So, although the case might look the same and the label says "Commodore 64", the boards may be completely different.
Finally, the C64GS game console was released in 1990. Basically it was a re-boxed C64, without a keyboard or any other interfaces, except for the cartridge slot on top.

Bob Van Sickle reports:
The C 64 was originally developed as a video game machine engine to be used in video arcades. The idea was to have a basic machine which could be programmed for a different game when the previous one became out-of-favor, and one would not have to trash the machine. Hence the good sound and graphics capabilities. What happened? The market here in the states for game arcades collapsed, and Commodore attempted to recoup their investment. This well documented in an article published by the IEEE "Institute of Electronic and Electrical Engineering" which I read, but cannot recall the year.
