  • Considering the Apple II had a single memory location to poke to make the speaker emit a tiny "click," does anyone know how exactly they multiplexed two voices in this program? I know this program did it, as did EA's Music Construction Set. However, I don't remember any games ever achieving this during gameplay. There was also another demo program that multiplexed voices in a time-multiplexed way, where the speaker was alternating between the two about 20 times per second (maple leaf rag).

  • @gansan00 when you click the speaker, it sends the cone out. but if you poke the address again to make the cone come back, if you do it fast enough you kinda get the cone to hang out in the middle (in between states). If you modulate the time in between pokes you cause the cone's movement to achieve audio frequencies. The most popular game I remember that used it was Castle Wolfenstein. The guards would yell at you "Halt! Comenzie! Aus Pass!" Pretty wicked for the time.

  • OMG !!! I traveled to the past Thanks so much...

  • Loooooool

  • I hadn't heard this live in about 20 years! Although, every note has been stuck in my head since the late 1980's. I finally broke down and spent the past week researching what the music is. I mean, I did every possible search. After tracking down that it is a sonata, I went through every possible composer... Bach, Beethoven, Haydn, and finally found sonata 15 by Mozart. Then I cross referenced "Mozart Sonata Apple II" and found your video. I never EVER thought I would hear this ever again!

  • Oh my gosh this brings back memories.

    I had a ][e

  • J'adore, que de souvenirs sur cet ordinateur qui fut mon premier apple. Merci

  • This is great... one should not underestimate what a great work is done here... getting virtual sounds out of a box is something that we see every day. But this first time, was really a genius work! thanks for the vid.

  • Wow- is this Christmas 1984? This brings back memories!

  • For me it brings back memories AND is making new ones as we speak!

  • The arch. of the PC was set by IBM, not MS. It's cool to hate Gates, but nothing here or in the sound of the original PC has any bearing on that.

    The PC architects drove the PC speaker from a timer chip which actually gave them more power. Woz drove the cone speaker from a bit memory-mapped to the Apple address space. You peek or poke one location.

    Instead of trying to kick MS over this we should be marveling at the genius it took to create such sound from such a primitive system.

  • I guess you're right, if I offended you with my early comment, I'm sorry. But the point still remains that Apple are far ahead of IBM, that was the case then and still is now.

  • I found this video months ago, and while watching it I realized something. No IBM PC could do this back in 1984, because Bill Gates is a dickhead, people say how cleaver he is because he's autistic, I say the reason why Microsoft suck and why they're so behind is because Bill Gates is an autistic cunt. I'd much rather use one of these machines for day to day tasks than use a PC with Windows Vista.

  • Easy boy.

    a) the IBM PC actually had a timer chip to drive the speaker, so you could make the computer beep and stuff and actually do other stuff, even though you couldn't do cool fake analog audio like you could do on the Apple.

    b) That had nothing to do with MS or Gates. That was 100% IBM Boca Raton.

  • Certainly a lot of early PC's had an internal PC speaker that could produce simple beeps and things, but I don't believe it could do the kind of stuff shown in this video. Yes I understand that my last comment is going to offend a lot of people, but I'm so tired of Microsoft and their fucked up ways of doing things. OK, you say the PC Speaker business had nothing to do with MS, very well, I understand that, I just want to hang shit on Microsoft, I'm not even an Apple user, but I want to be.

  • It is possible to do things like this with the IBM-PC speaker output; though i've never heard anything as ambitious as this.

    The genius behind this particular corner of the IIc demo disk is Paul Lutus (also responsible for TransForth and GraForth). It was one of the demo pieces included with The Electric Duet—A package that allowed the composition of little ditties in 2 note polyphony, on any Apple II (even the original), and led to the squandering of an awful lot of my time in the '80s. ;)

  • I tried in vain to get The Electric Duet to send one note to the speaker and one to the cassette.

    I did manage it with a standalone Integer BASIC program that played a movement of one of the Brandenburgs. With an external amp and speaker, i had a stereo Apple IIe, in all its TTL actuated glory. :P

  • @krb3141 and since apple used DOS and even has "microsoft (c) 77 to 84" silk screaned onto the motherboard right below the rom on the apple IIc you can actually kind of THANK bill for this one :P

  • @Lachlant1984 LMAO LMAO LMAO

  • @Lachlant1984 haha you hater

  • Comment removed

  • can this get high speed internet?

  • Are you crazy, of course not. Not on an Apple IIc anyway.

  • zappa used the same thing to wright alot of his stuff!

    very cool thanks for postig!

    yes i am still impressed,but then again,i am an anything old (is this really that old?haha)and musical.........loves it!

  • This used to impress us! We used to stare at it in awe. HA!!!

  • It used to impress us...and it still impresses me, knowing now that speaker works, and knowing that they did this in the eawrly 1980s!

  • Good question....the music is at LEAST 250 years old.

  • I lol'ed !

    that's soo cool (:

    And the computer is so old I love it.

  • wow this brings back so many good memories!

  • the cess

  • It's amazing how much technology has moved forward....This was one of the most amazing computer features of the early 80's, and now we have iPod nanos that is like 50X smaller, and plays real music, and is all around better than a 1983-84 Apple. That is sooo wierd.... This computer should be highly respected!

  • Yea, but the screen is smaller on an Ipod...

  • That's one of the purposes of the iPod.

  • this IIc released 2 years after the commodore 64. LOL :))

  • woa wen is that computer from the 1400s?

  • Why would you expect that computer to predate Mozart by 300 years?

  • it a joke homie

  • Thanks for bringing back such great memories! I would play this over and over for hours when I was about 7.

    Loved the whole "Apple At Play" disc!

  • That's cool, that thing was released the year I was borne, my family didn't have a computer until I was 11. can you please post a demo of the other utilities on that disk?

  • Hihi... that computer is older than me ^_^

    Thanks for posting this, it's funny... and don't mind the idiots who complain, it's your right to upload anything you feel like uploading, isn't it?

  • I remember being 7 yrs old and demonstrating this to my father. I'm sure he felt justified for the $2,000 he dropped on a //c back in '84! Hahahha.

  • So nostalgic but a bit exciting

  • VERY, VERY GOOD! Apple computers are the perfect fusion of art and science! I loved that song, i had it (21 years ago) on my Apple Laser ][c computer (a brazilian apple 2 clone) ... Hugs from Brazil! congratulations!!

  • I think digola say it, because he likes old computer like colectors like old toys.

  • I noticed it was playing 2 tones at once. How is that possible for a sound system that can only play 1 tone at a time?

  • It can't even play 1 "tone" at a time. It has a speaker element that can be clicked. That is, the element can either be sent in (if it's already out) or out (if it's already in). Now, if you control the speaker element fast enough (as in send the element out and then call it back in before it even got completely out) you can do a rudimentary amount of waveform shaping and can create a crude polyphony.

  • i managed about 10 seconds..

    whos saddest..you for doing it or me for listening?

  • You for posting.

  • I got mine to play "Wanted Dead or Alive". Not goin there again.

  • Way cool! An Apple //! And it still works?? Brings back memories. The lab in college used to have Commodore 64s and I remember spending many hours learning how to program the synthesizer. The c64 had a voice synth called SAM and when no one was around, we would program it to say obscene things! It was hilarious!!

  • Greetings! I can see you've posted this comment a couple of years ago... Still, I myself have three of those babies and all still in working condition! This computer doesn't die on me! (Well if it doesn't get spilled some coffee over) It's a piece of electronics I have at home among many other things...

  • Its like running into an old friend you haven' t seen in a long time. I have an IBM PC (the original) and a TRS-80 model I with a whopping 4k of memory. The refrigerator has more memory than that! We could start a museum.

  • A museum is a great idea. BTW, check my Apple //c videos. I have to apologize a little for my bad english pronounciation, haha...

  • nice cute apple! nowadays apple looks very good

  • OMG ! great video man, i remember my first computer ! was an Apple //c ! hehe, i remember video games like Conan, pacman, Lode Runner, etc

  • Wow, this brings back memories of my own //c. I left that Sonata song playing on auto-repeat for a whole afternoon or longer. Also spent many hours playing that lemonade stand game ("Lemonade" in the opening menu)...led to many hours typing in my own Applesoft Basic games from books and magazines. I should dig my old //c out again someday...wonder if it still works.

  • We still have our Apple IIc - and is still functioning. I thought the Music Recital from the Apple at Play disk was amazing when I first played it - thanks for the reminder krb3141.

    The days of typing public school projects in AppleWorks and printing them out on a dot matrix printer.

  • I know what you mean. I remember when I first got that machine and played the Music Recital program I was mesmerized. Of course, if I had ever owned a C64 I would probably been angry :-)

  • Hahaha great..

    amazing sound.. so close to piano:D

  • hahaha!

    it's better than with Gould!

    :-)))))

  • LOL CUTE. I owned that for 7 years. Good memory.

  • LOL

  • omg...lol...thats horrible :O

  • Perhaps, but it is definitely a trip down memory lane for any Gen-Xer who had an Apple 2 or used one in school!

  • haha yea

  • game boy?

  • "Mozart's Sonata in C, K545 *performed by my Apple //c*"

  • Ahaha, bon! xD Tres fantastique. Amities, xx

  • putzzz, muito massa

  • thanks for a programmed version of the Mozart sonata.Always wanted to hear it with precise timing. Not much different from the playing by a child prodigy.

  • Cool. I was searching for this piece, because I am playing it and wanted to hear a good version. But, this one certainly beats the others. :D

  • hahahahahahaha, cool computer.

  • I am overwhelmed! Truly overwhelmed sir!
