In 1980, Commodore Business Machines, building on the success of their PET (Personal Electronic Transactor) line of computers entered the home market in force with the introduction of the Vic-20. This little machine, basically an oversized keyboard with a computer stuffed inside, was sold as an alternative to the gaming systems that were popular at the time (Atari 2600, etc.) The Vic-20 was actually more powerful then the game systems and had the ability to do more then just play games since it was, after all, a full computer.

The machine accepted cartridges for much of its programming with an optional tape drive being the most commonly used “mass storage.” The machine is, however, compatible with the disk drives that came along a bit later with its big brother, the Commodore 64.

The VIC-20 in my collection comes with its original box and power supply.

The Commodore 5.25 inch disk drive model 1541

It also comes with a Commodore 1541 5.25" floppy drive.

The Commodore 1541 disk drive box

The disk drive is also boxed.

I've also got the original VIC-20 manual (not pictured. . . yet) but no cartridges or software for this machine.

The VIC-20 in my collection was donated by Rick Collette along with several other very nice items!

Had one of these when they first came out. It was the coolest thing at the time. I did my first basic programing on it. And saved my work to the tape drive. Couldn't have been more thrilled.

Pirate Cove aka Pirate Adventure by Scott Adams. Text only adventure. Just played it again after 25 years. Bought back so many memories. My dad and mum around my vic20 helping me with my spelling 'drop parrot'&'take mongoose'. I did what I could not do when I was six, I completed it, mainly because I still remembered some of it. This game conjured up so many adventurous yearnings in my early years that it introduced me to Treasure Island and then a lifetime of great literature. Thank you Scott Adams!

Looking for a computer such as commodore VIC-20 with tape drive.

I have 24 CNC (Computer Numerical Control) tapes (exactly like audio cassette tapes) that I need to convert to digital media such as CDs or DVDs.

Have been trying for 3 months trying to find a tape drive unit that will use these tapes in hopes I convert to digital media. No luck as yet.

In reply to some of the posts regarding Power Supplies, the Vic & C64 both use the same one.

(Submitted October 2, 2010 13:41:53 by SR)

If you are missing the power supply to your Vic 20. You can do what I did. Look up the specs of the power supply in the manual (I'd tell you but all is is buried in boxes right now), look for Volts (V) and Amps (A) ratings. Then go to your local radio shack and buy a variable AC to DC power supply that will deliver the Volts and Amps you need. Then buy an adapter that will fit the connection you need. You might have to rig something, but should work. Otherwise look on Ebay for an original.

Hello all I too have not only the Vic 20 still but also a C64. I have several cartiridges and about 40 Cassettes with programs on I typed in from the Compute and RUN magazines, as well as programs I just created myself. I can't even imagine the number of hours I spent parked at those computers which I had hooked to a 20 inch TV which I sat 2 feet away from( Probably the reason I wear glasses today lol) I still have the manuels as well. Also to the person looking for Pirates Cove and the COUNT I have them Both! :) Ahhh the memmories.. COMMODORE, YOU ROCK! I also have the Joystick and paddles. Cheers

Great memories, my first computer. i was 14 in 1983 and they had been recently discontinued and Zellers (in Canada) had them on sale for $99. I bought one and saved up for the datasette, a joystick and some books. I used the PET's in highschool and this VIC was similar so I had a lot of fun buying cassettes and programming from books and on my own. COMPUTE! magazine was also awesome to get monthly. I ended up selling everything after a couple years for $200 and my plan was to upgrade to something better, I saw that Atari computers had great success, I shoulda gotten a 64 but instead got a 600xl (atari). i never really got into it. Until finally, 5 years later I got an IBM compatible laptop with page white VGA. Years later I found a C-64 with disk drive and tons of games that someone dumped. GREAT FUN, the PET, VIC, 64 and Amiga were great in their time !!!

My first computer! My dad bought it for me when I was nine years old. He didn't know anything about computers but he knew they were the future. I taught myself BASIC on it, spent countless hours programming. I must have burnt out 2 or 3 power adapters from using it so much. I love this computer, brings back memories. It was the beginning of my life long computer programming career. I miss my dad.

The Commodore VIC-20 had some really great games. Two of my favourites were 'Radar Rat Race' and 'Clowns' which I still play via emulation on a PC. The only real limitation was the RAM, back in the 80s you needed at least 16 Kilobytes to do anything useful (wordprocessing, database etc..) on a computer. Without a RAM expansion, you would quickly run out of memory typing half of a 1 page document! Other than that, it was great fun and introduced many of us to computing.

Here's a good side note. The TV ad campaign for the Vic-20 wes done by William Shatner, fresh from playing Captain Kirk on the original Star Trek series. (who could be more hi-tech?) The script gave a very in your face message that if you didn't buy your kids one of these, you were a bad parent, because they could never keep up with other kids and as a result, never go to college, never get a good job, etc...

Look up the as on youtube... it's interesting.

I purchased a VIC 20 circa 1983. this one was assembled in England,later on I added a tape drive to it after a couple of months it malfunctioned it just went dead on me. I sent it back to the store to get it repaired.It was unbelievable I waited six months after complaining to get it back in working order it return back to me and I finally sold it to my nephew.He just had for a week and it broke down on him and after that I had to refund his money and it was once again returned to me.This VIC 20 was assembled in England during that period it was built(1982),Britain was involved in a war with Argentina therefore the workforce was reduced there was work stoppages at the factory due to supply and demand shortages,and also quality control at the plant.So therefore you had poor build quality.

I've bought the VIC-20 in january 1984, at 11 yrs old, and as Don wrote, it was the seed of my life in computer science. Now I'm trying to use some emulator to re-run my old programs written on tape. I would like to record old cassettes on my PC using a normal hifi, connected to the line- in audio port and saving into WAV files. The problem is: what frequency, and number of bits should the samples use? E.g: 22050MHz, 8 bit? Less, more? Any hint is well considered. Thank you.

The Commodore VIC20 was the first computer I ever owned. My parents bought it for me in 1983 for Christmas. I was 14 and we had moved to a new town. My VIC20 was the only friend I had at the time. I spent many a sleepless night programing in basic and playing games. Today I am a System Technician in the IT department for a large international comany. I owe it all to the seed that was planted during those lonely days I spent on my VIC20. I still own it and take it to show my kids where it all began.

(Submitted July 18, 2006 09:46:28 by Bruce LaBonte)

My first computer was a Vic-20 that I bought at Toys-R-Us. I used a 13 color TV as a monitor, and a standard cassette tape drive and a disk drive (a 1540, I think) for external storage. It did have an expansion port on the back that would accept cartridges for memory or programs. I remember hearing about a multi-cartridge card that would plug into this port, but I could never locate one. I did buy enough memory cartridges that if I had found this card, I could have boosted the memory to 16K. Unfortunately, I tossed this computer several years ago when I was cleaning out a closet after my wife and I bought an IBM Aptiva. It would have been fun to play with it some more.

The Vic-20 had plenty of expansion, even though it is listed as having none.

It had a rs232/parallel port running from the second 6522 VIA 0.156 pitch iirc, a proprietry tape connection, a video connection, a predecessor to the scsi bus which could take diskdrives and other peripherals (it featured disconnect and other nifty features), and expansion port which was a direct connection to the data and address buses of the cpu which could be used to add memory, rom cards and specialist interfaces, a joystick port was also present on the side which could take a digital joystick and/or two paddles/analog joystick (370Kohms only iirc)

This is all off the top of my head. But I used to know the vic inside and out including using it for many robotics projects when I was much younger.

(Submitted July 24, 2005 16:23:07 by Dave McLain)

Didn't the VIC 20 originally come with a disk drive called the 1540. From my understanding it ran at a slightly faster data rate than the 1541, which replaced it. The reason was because the Commodore 64 ran just a tiny bit slower due to the fact that it had more screen memory to refresh and it was therefore not compatible with the 1540. This is also why many of the fast load utility programs for the 64 would blank the screen during program loading. I think it's possible to make the 1541 run at the 1540 speed through some sort of software utility so they must not be all that different. Great site too by the way...
