Commodore introduced the Plus/4 in the early to mid 1980s (about 1984ish) to replace the VIC-20 and Commodore 64 models. The machine was a compact case with a full-travel keyboard sporting four built-in applications (hence the plus 4 in the name.)

The box for the Commodore Plus/4 computer

The Plus/4 in my collection was donated by Rick Collette along with several other very nice items!

The Plus/4 uses standard Commodore Serial Bus disk drives and printers just fine.

Having owned a Plus 4 for about 4 1/2 years now, all I can say is good luck to anyone in the US or Canada trying to find peripherals or software for them. The cassette players can sometimes be found but the floppy drive is next to impossible. You have to hunt around in Europe to find one of those as it seems most of them ended up there. Most of the software, it seems, is there as well. You CAN use the C64 floppy drives with these, but they are much slower than a 1551. There is also a cassette adapter that allows you to use the C64/VIC 20 cassette player that turns up on ebay from time to time but it is usually $25-$30, which is about what the 1531 cassette player sells for. Cool computer but difficult to collect for.

I have a working and much loved Commodore Plus/4 with the user manual and with 10 games, which includes favourites such as Icicle Works, Fire Ant and Treasure Island. Anyone interested i'm currently selling it on ebay:

Mr. Puniverse and KickStart! YES,YES,YESSSS!! I was 14 years old, when I got my Plus/4. I loved it. I learnt programming it by assembly code. I loved its basic language too. Wonderful young ages :)

(Submitted July 24, 2009 17:09:16 by Cinoti)

plus/4 was derived from a successful and cutting edge (at the time) TRILOGY. When Jack Tramiel left for Atari, the plus/4 was in final build, as Jack's last project, COB Smith all but killed the plus/4. less than a month I had to cut the code in half. I do know know what to say to people that do not like the software, after all I had lots of people that swear how much they liked it, earnestly!. It was comparable to Lotus 123 on Apple. I stuffed a lot into a small area. Don't forget how novel it was to push a button and have software applications ready to go. I always felt bad for my audience, that Commodore had dropped the plus/4, and I probably should not have contracted to them in the first place. All in All, for every naysayer I remember thousands of supportive post cards & letters. ..and for that I am grateful! ..David W. Johnson my site is where I current am. remember keyword: plus/4 (when keywords are activated)

Built in software would have been great if it had been really good software.

I still have my plus 4, it still works, even though it's been hidden in my loft for 20 odd years, and i've still got Kick Start, Icicle Works and all the other classics, It gave me so much fun as I kid, I love it.

I got a Plus/4 when I was 12 for $100. I loved using it, even though I had absolutely no games for it. I did tons of programming on it, including a D&D character generator, dice rolling program and a phone auto dialer. I still have it. I'd love to find some game carts for it and get it up and running again.

I had a Plus 4 bought for me for Christmas in 1985 when I was 9. The best christmas present ever bar none!!! Icicle Works, Treasure Island, Kick Start. Those were the days. No matter how powerfull PCs and consols get now, they can never evoke the same feeling of excitement when I was a 9 year old boy!

Commodore plus/4 was my first computer, back 20 years ago. Can't believe it's so long. I had only a datasette with it and two commodore joysticks (I think they were 1331). Can't remember the first game I palyed, I think it was Mr Puniverse. I also remember Kikstart, Aufwiedersehen Monty... I sold it in early 90s and I regreted it. Now I bought one on ebay and also have the 1551 drive. It's really nostalgic to come back to the same things after such long time.

(Submitted February 10, 2007 14:23:36 by Jim Peters)

I also am a Commodore computer collector. I have a Commodore 1551 disk drive for the Plus/4 but I need an operators manual so I can try it out. If you have one to sell please contact me.

I had a commodore as a child, me and my dad would play it for hours, and it was a great laugh, especially icicle works, and fire ant... So I finally find a working model, all in time for my dads 60th birthday, and after two uses they keyboard has stopped typing. It still turns on, it has the screen ready to go, but the buttons will not type, any help would be appreciated, you'll make an old man very happy (and suprised for his borthday!) Thanks

Very interesting site that I just found. I started out with a Com. 20 and didnt do much more until 486 came along. I did come across 4 brand new Commodore Plus 4 machines still in the boxes plus an additional 4 new power supplies. I have never used these machines and was interested in reading the posts about them.

Why do most of the comments on these pages, refer to computers for sale, or people looking to buy. I do not believe the Webmaster intended for this to be an area for people trolling for stuff. This is just my opinion, but I keep reading the comments hoping to see peoples various stories and such of the computer shown, not hear how you need to buy one or have one for sale. I am sure there is a much better forum for that than here. Also, most of the said 'trolling' would barely pass an elementary school grammar test, and some general netiquette would help, along with basic manners and outdated terms such as 'please' and 'thank you'. Thank you for the ability to air my opinion and thanks for taking the time to read this (if anyone does), Steven

Actually, the other Commodore models were not intended as replacements for the VIC and 64. They were aimed at an entirely different market and were meant to be sold simultaneously. The Plus 4 and C16 started out as the 264,364 and 116 and were aimed at the high end home user and professional user who might otherwise have bought an Apple or IBM PC. The VIC and 64 were marketed towards gamers and more casual users. They weren't compatible with other Commodore peripherals.It used a drive called the 1551 and the cassette was the 1531. The ports they connected to were different than those on the VIC and 64 and they came in a matching black color to go with the Plus 4 case.

This computer brings back some mixed emotion. This machine brought me and my grandfather together in beautiful ways. We were addicted to Fire Ant, kick Start and centipede. Thinking of him now makes me swell with pride, he was the best man I ever met, I wont forget him nor this machine. I learnt assembly language on it,, My career in programming started on this highly underated machine. I still own one and wouldnt let it go for any price.

I rescued a plus/4 from the dumpster on clean-up day. It is in the original box with only the power supply and the manual. If anyone wants it and is willing to pay postage from NJ USA or preferably pick it up, the first (US) reply gets it. I have no use for it.

We had the Plus 4. We got ours from Debenhams Ł80 or thereabouts. Oh what happy memories...waiting for the games to load from the cassette!!! LOAD.Ah back to the age when we were all young and didn't know any better. Fire Ant, Icicle works and Treasure Island. Does anyone else think that the pirate look rude waving his cutlass around or was it just me and my dirty 12 year old mind? Mind you Dad and Mum both thought the same as well!!!

I loved this computer. I was 13 when I got it and spent many nights programming in BASIC, creating games and playing games. If it wasn't for this little beauty (let's face it, it looks a lot better than the C16 and C64), I probably wouldn't have been a software development.

I had the Plus /4 's weaker brother the Commodore

16. I eventually gave up on it because we

I did learn Generic basic programming though,

I still have my C = 16.
