Macintosh original demo disk...
Posted by: tjjq44 on 2014-12-17 15:27:04

As Supertramp said: "Dreamer... you know you are a dreamer"...

Who knows... maybe there is still a copy of the holy disk somewhere?

So it is a system, with an auto run of some hypercard stacks that spoke.  Real history.

That would be awesome to get a copy tho.

Now I started looking and other than the video no one even seems to have asked the question if there was ever a copy.

Yes, its been asked. I think here. There was even discussion of reproducing it. The first consensus was that a 512k board would be needed, no way to run it on a 128k with how little RAM it had.

I think the conversation also discussed the custom video out card created to have the Mac display the demo on the large projector.

The bigger question, what happened to that special Mac they made for the presentation?

Posted by: Macdrone on 2014-12-18 03:20:03
Ya, seems like a lot gets lost in the shuffle.

Well, its one of those things that at the time seems like just another piece of hardware, with no one knowing how truly significant it would end up being, and how valuable it would be to preserve it for posterity.

Isn't there a story on folklore.org about it actually being slaved to a Lisa that was doing the heavy lifting?

I made reproduction see video here: 


I also know who owns the original disks and has a copy but wont share it ...

My version needs a 1 MB of RAM and Hard drive.

I never understood this. :-/

The story: http://www.folklore.org/StoryView.py?project=Macintosh&story=Intro_Demo.txt

I was thinking of a different earlier demo when they used the Mac as a Lisa terminal...

Posted by: Macdrone on 2014-12-18 12:24:01
Yes that's sad they won't share a copy.

Posted by: unity on 2014-12-18 12:28:15
I actually totally understand why the owner will not share. It would just become commonplace software. Right now its unique. Thats the problem with software, too easy to duplicate.

Posted by: jsarchibald on 2014-12-18 13:11:54
Well at least show it booting and doing its thing, and put it on Youtube.  It's like having a vintage Ferrari that you don't even look at, let alone anyone else.  I get not sharing the file, but at least share the routine with a modern HD recording.

Posted by: tjjq44 on 2014-12-18 13:58:34
In fact, the value of its original is huge for now, one day we'll probably see en auction on ebay at outrageous starting price... Maybe the next owner will be more selfless and share if not a disk image, at least a youtube video of it 😉

If he waits too long there won't be a 400 k floppy with the ability to prove its that software on that disk.

But whatever to each his own.

Posted by: uniserver on 2014-12-18 14:20:32
heck so they cheated with the Music, ( cd )

they cheated with ram ( 512k )

i wonder if he cheated and used an 800k floppy disk...

or the disk was just an HD20 init 🙂 and it had an internal HD20 ... 

Posted by: tjjq44 on 2014-12-18 22:58:07
A 800k MFS disk, maybe but I don't know if sony had double sided drives prototypes at this time...

For the HD20, it's unlikely since the DCD protocol wasn't already invented!

Posted by: uniserver on 2014-12-19 00:38:15
what came first the chicken or the egg?   I'm sure the IWM…  WOZ being the smart cookie he was… had DCD type thing in mind, after all it is supported in hardware.
