C64 Demo Sabrina (digitized sound) DDG (on real C64)

[fortressofcomfort]

SID Power!

[tiamarquez0]

This video went viral on Hungary

[lakepalmer]

COOOOOOOOOOOOOORRRRRRRRRRRRRRR­RRRR!!!!

[keoni29]

Lol this music was probably written on an amiga!

[SpearM3064]

@keoni29 Actually, no, it was digitized, just like the description says. watch?v=eiuHdUkuRi0 for the original.

[jhclouse]

iTunes 0.0.1?

COMMODORE NEVER DIE!!!

Declared dead live longer!!!

[zigazig1980]

Gone are the days when it felt like you bought a computer that never felt like it was running at it's full potential, always felt like it had more to give, and with more advances with games and programs it felt like you were getting closer to something even bigger, now it feels like you just buy the console or pc and it runs and looks awesome already no challenge

[giacjack]

c64 still the best!

[triptothebeach]

C64 still rulez!

[DankWin]

definitely would have jerked off to this in 1987

[0u8shirt8]

@DankWin

Yeah, me too.

[way2muchNFO]

1987 24 years

[johneymute]

impressive 8bit sound for a commodore 64,even the gba has only 2 8bit dac,s!!!

[Zontar82]

ohh Sabrina Salerno...still hot

[teknicalteknical]

The first Demo I ever copied from the BBS user "demon lord" in Ottawa, Canada, around 1990

[Nyquist80]

she was italian showgirl!!!!!

[CriminalMacabre]

Sabrina's naked boob, the fondest memory of the spanish christmas of the 80's

[MrMarkzilla]

Lets see a Speccy do this!

[FSS187]

felállt a faszom a zenétől meg elélveztem whoáááááááá.......

[Acid1K05]

i dlatego kocham c64 ! w tamtych czasach takie demo to był szał !! :-))

[harleykman]

I remember this demo!

But I had no idea who Sabrina was, or where the music came from. Not until Youtube came-along and showed me the original (almost) topless video

.

[OpticalFascism]

Stating that it was recorded from a real machine is so snotty.

[0817tube]

@OpticalFascism what is your problem ? Why should the uploader not mention from which source he recorded the demo ? I like it when people tell if they recorded the demos from a real machine, a software emulator or a hardware device which emulate the real machine, because some demos behave different on different devices (for example glitches can occour, music can sound different on different devices and so on).

[SpearM3064]

@OpticalFascism Actually, the source is important. Some demos will not run on an emulator (for example, the Robotic Liberation demo for the VIC-20 relies on tricks that only work on the original chipset). So if the demo requires a real Commodore 64, then he should say so. There's nothing snotty about it.

[kdixon7783c]

I bet it took ages to download this back then.

[SD78]

@kdixon7783c

Download?????

[SD78]

@kdixon7783c

Download?????

[maiki60fps]

@kdixon7783c this demo fills up only the RAM so its no more than some 60k... meaning its just a single-loading game nothing more...

[harleykman]

@kdixon7783c I remember downloading this as a 30 kilobyte file over my 1200 bit per second modem (about 1k speed). So doing some quick math:

30 KB * 8 == 240 kilobits / 1 kbit/s == 240 seconds or 4 minutes

.

If it were downloaded over a "modern" 56 k modem then only 4 seconds

.

[kdixon7783c]

@harleykman Those were the good ole' days, though. Nobody hardly bats an eyelash at what these machines can do now.

[propinki]

thanks god for You, real thing not emu crap in near time I gona record some music too but I dont have tv card soo it can be crapy quality ;/

[coolgeorge423]

DIG-I-TIZE DE-siiiiign...DIG-I-TIZE DE-siiiiign...DIG-I-TIZE DE-siiiiign...DIG-I-TIZE DE-siiiiign...

Intro sounds awesome, <3<3 Sabrina Salerno :3

[KaslarProductions]

your tv added alot of extra noise..... great sampling though......

[xanaki]

Yes, as a original member of DDG, we were first to do this in Finland and one of of the first in the world. Thank you for all your commets. Mr Moonlight/DDG :)

[xanaki]

The oscillator was realtime... :)

[harleykman]

@xanaki Not really. The first digital sounds were created early on, for games like Impossible Mission

.

[fenriz218]

Jessus ... are we really that old?!?

I also recall certain "adult" games and slide shows ... man, compared to today, these were the dark, dark ages ...

[leknightcluber]

1982 home computer that could digitize music

exelent

commodore rulez

[Juha023]

Yeah, I remember when I loaded this first time on my C64... I still have this on my floppy disk, and working well!

[Abrimaal]

I have the same demo for Spectrum with the same digi music :)

[Klinker65]

C64 is like Sabrina Salerno ... timeless!!!

Thanks frome Rome (Italy)

[Mauryx971]

Grande merito al caro e vecchio C&$, ma sopratutto Sabrina sei sempre BBONISSIMA!!

[FIXTREME]

How can you play real music on an 8bit machine? Im planning on using this on my next atari lynx homebrew.

[jayelem]

I had this same Sabrina Demo , and also had one for the Billy Idol song Flesh for Fantasy.

C64  Rules

[VikutaaChyaaruzu]

This is the reason why I plan on making my original music through old computers. :D

[CRYP77]

COOOL i know this demo. Commodore 4 EVER! ^^

[eurominet]

I remember well this demo.

Watched it quite a bit !

Back to time, I loved it much because most of the digi sound put a blank screen, and this one has a picture and sprites.

But, I love even more Cycleburner's demos .. from CONTEX.

Do a YT search with "cycleburner contex"

(NOT "context")

[Filosofen88]

The fact that this is played completely on a home computer form 1982 makes it fucking fantastic! Back in the days when PC's were just dead DOS machines with plain B/W text.

[OBSysteme]

@Filosofen88 ... by the way... the Commodore 64, it predates DOS in a way... you run stuff in Basic or you feed it machine code.

[SpearM3064]

@OBSysteme The "DOS" was actually built in to the disk drive, which had its own CPU, RAM, and BIOS... basically the disk drive was a computer in its own right! It saved memory because, unlike other computers of the era like the Atari 800, you didn't have to load 'DOS' into the computer's RAM.

Of course, it would have been nice if Commodore 64 BASIC had included disk commands instead of making you type stuff like

OPEN 15,8,15,"N0:GAMES DISK,A1":CLOSE 15

to format a blank disk.

@Filosofen88

Comparing C64 voice emulation with Microsoft Sam introduced in 2001 as a feature in Windows XP, people may wonder: what went wrong in computing in this period of time?

[leszken]

@Filosofen88

Comparing C64 voice emulation with Microsoft Sam introduced in 2001 as a feature in Windows XP, people may wonder: what went wrong in computing in this period of time? There is so few improvements comparing to booth computer system parameters!

[NmGab]

@leszken

Not to mention the nice speech synth on the Amiga...

[SpeeBeta1]

Sounds like Apple 2GS

[demonfister]

Amazing

[kubel101]

this has got a soul !

[kinmanyuen]

damn..... awesome!

[thyzzie]

Holy fucking shit... That our beloved 6581 can handle such amounts of digitized sound. I need to get this demo's floppy somewhere :D

[Chrfilmer]

I LOVE THE C64 4E

[GianniA]

ahaha great Sabrina Salerno!!! Roba Italiana ragazzi!!! ;)

[SteppingWolf]

Looks like somebody missed the download link. And if that's not enough, play "Mega Apocalypse", it's loaded with digitized effects + soundtrack by good'ol Rob Hubbard.

[ELGOCHORNII]

What A FAKE Ha Ha Ha

[AY3EIGHTYNINE10]

Get an emulator and see for yourself. He did post the disk image, after all.

[djsmithy]

I just realised there that its a real time oscilloscope in the video and not an animation!

Seriously cool.

[mackhine]

There was another one that had digitized acid music playing and a bunch of smiley faces flashing all over the screen.

[randomunavailable]

Acid demo is memory serves?

[97channel]

NO WAY!!!

That's crazy! So my good ol' C64 was capable of this?! OMG, seriously? Am I missing something?

Let me get this straight, so this demo can be played on an ordinary C64?

If that's so, then I need a moment to take this in. Pinch me, this surely can't be possible!

[drammensveien1]

marvellous (-:

[randomunavailable]

I can explain how digi sound worked on a c64. The sid chip has 3 voice synthesizer channels, and 1 volume control. The volume control had 16 levels, from 0-15. When you changed the volume on the SID, it would produce a "pop" in the speaker.  People discovered this on the SID chip and basically that became the digital sound channel. It was basically a 4 bit digital sound channel, although that's not what commodore had intended at the time, people still exploited it to this effect.

[155IE]

AFAIK, playing "digital" sound required you to produce constant sound (infinite sustain phase) on one channel and then simply alter it's volume.

[DXMDEALER]

Are you sure of that info? im pretty sure this is PCM

[randomunavailable]

Hey, I wrote a small digital sound app on the c64 way back in the day, I never used the sid more than the sound volume register, and I still managed to get digital sound. A friend of mine even showed me that if you SBC #$80 from Amiga IFF sound files, you effectively converted Amiga sound files to c64 format. =D Much fun was had.

[Jawattdenn]

That's only one way to play samples. There are other methods which allow for full 8 bit sample replay and you can even use the SID-filters on the sample replay, see video 5CFCyQ7s2JQ.

[randomunavailable]

Well that is seriously impressive and amazing all at the same time. Before it even scrolled I though test bit, and they managed to pull it off.

[Jawattdenn]

No, it's not the test bit method. Test bit doesn't allow to use the filters on the samples and also has less replay quality. The replay method used there is based on using the oscillators directly.

[snake2006]

How the hell is this possible?

That's impossible. But yet here it is.

Christ this is crazy.

[djsmithy]

Christ thats extremely impressive!

I didnt know the c64 could produce sound that clear, the pcm sounds in the games were not as clear because there wasnt as much processing power left for the audio.

Im guessing you own a c64c yeah?

the 8580 sid chip would explain why you had to amplify the sound so much, PCM playback was a lot quieter on it compared to the older 6581 chip.

[maiki60fps]

even the 8580 could be somehow tweaked to have digitized sound played loud, since I used to own C64C and had it "repaired" by a technician so that I could hear those digitized drums in awesome unbeatable C-64 version of GP Circuit...

I cannot tell you what he actually did with the 8580 but it worked....

perhaps has to do something with the filters they changed or bugs they fixed following the old 6581....???

[djsmithy]

Thats interesting. The filter uses external capacitors alright, that are not in the sid, but the filter is not used for the digitized playback.

I was going to say that he may have replaced it with a 8580, but sure he'd have to of changing the voltage going to the sid then, which would be a lot of effort!

Cant figure out a ligical reason.

[ybbek]

It's easy, actually:

When the 6581 was designed, a DC offset was deliberately added to the sum signal, so that if the volume register was modified, you could form PCM samples with that (yes, it WAS intended). A decoupling capacitor then got rid of that DC offset.

And whoever "optimized" the design for the 8580 didn't know about that, and the DC offset was gone. Solution: Add it again by applying +5V to the audio in through a resistor.

[djsmithy]

Thanks a lot for explaining it!

might just save me from buying a 6581 just for listening to the sampled tunes, and doing that mod instead!

[AY3EIGHTYNINE10]

I prefer my C64c myself....but if I find myself too unhappy with my 8580, I suppose I could try swapping the mainboard with one of my many breadboxes. :P

[jci10]

That explains why the C128D's sound sucks compared to a real C64...

[bisexualbuffthug]

Thats a miracle!!! You made an ancient home computer do what it was never made to do!!! You got a 1980's commodore 64 to play regular music!! Your awesome!!

[blakegriplingph]

Proof of concept for the C64, eh?

[SegaMegadriveMic]

This is awesome! One of the best C64 demos ever made :)

[TALyeah]

Yep :-D

[inphanta]

Oh man, I remember this tune. Conjours images of men in tight white t-shirts. Probably one of the gayest songs ever recorded.

[daddlerTL]

Look in the description of the video. I added a download link there.

[matzux1978]

where can download the .d64 disk image???

greetings

[cosine303]

go to c64 (dot) ch... and search for "sabrina"

it will come up..

[matzux1978]

thanks! :D.

[p4r4n01m1a]

Bellissimo Demo con la formosa Sabrina Salerno ... Boys Boys Boys I'm looking for my good time!

[mjshikeli]

Yes 80's tehno! Times of SABRINA & C64... Boys, Boys, Boys, bo bo bo bo boys.

[drvector]

magnifico!

[Powzone]

LOL! I had the thougt right now, that this was the way techno could have been invented... Sampling 4 beats and repeating! :D

Great work anyway!

[balorduomo]

Really great
