Specifications for the sound recorder program & a low memory image for a Mac, a long request...

Dear the developers on this squeak list,

I have a desire to learn about the inner workings of the sound
recorder program that lives inside a squeak image. However, owing to
rot and poor maintenance of my ancient collection of Apple Macs, I am
almost forced to do my work on my PowerBook Duo with 4MB of RAM.
Because of this requirement, I am looking for a pre-shrunken image
with that application in to tinker with. Because of the age of the Mac
I am looking for an adequate squeak app to interpret it from (needn't
be the latest) - but even though the new squeak VMs support ancient
Mac too (I've run it on 7.6, my Duo runs Mac 7.1 and has large (or is
that: low) memory problems (=4MB).

The task I have in mind is to morph the sound recorder program from an
entity that saves the resultant audio data somewhere to something that
operates on a sound input source in memory and takes action
appropriately based on the audio "data stream" being fed to it. [1].
Naturally, my Duo might cause me some more headaches, but I look
forward to meeting them head on (so to speak :)).

Thanks,

R N Hyer

[1] If you know of an application that comes closer to the description
I need - and lives inside a squeak image - and is not the sound
recorder program - then feel free to tell me that it has already been
invented. (Or at least the major part of what I am seeking to do...)

Well I *think* Squeak 3.8.9beta7 was the last os-9 based VM. It might  
run under os-7.5.5 which was the earliest OS tested, mind 7.6.1 was a  
bit better.
Personally I found os-9.x way more stable but I'm not sure if this is  
an option for you.

You should look at the 3.8.x Release Nodes.rtf via
ftp://ftp.smalltalkconsulting.com
and decide which VM version might be best for you.

Ah, I should ask is this a 68K powerbook duo?

Really one should consider upgrading your hardware, although laptops  
are more expensive, you can I believe find G3 or G4 based desktop  
machines for  I'd think < 25 pounds, or nearly free since these  
machines are 10 years old, hint worthless in the eyes of the public.  
http://en.wikipedia.org/wiki/Power_Macintosh

I'd suggest looking in second hand stores, salvation army, thrift  
stores, computer stores, etc for oh say an 8600, extra ram again  
likely a 5 pound cost, and a monitor,  pick your size, varies I think  
from free to a few 10 of pounds, I've seen plenty disgarded because  
of people switching to LCD screens, you'll likely need a VGA adaptor  
plug to use a PC based monitor.

With only 4MB you are hard pressed to have any type of performance  
since the 2.8 or 3.x series of images were 8-9MB in size.

I did build a MVC VM for Dan in 2001  (3.0alpha9MT) which fit in 1MB  
of memory using an image he made that was a 588Kb Squeak 2.2. image  
of sept 23rd, 1998.
If you want these please let me know.  Lastly I think for 68K the  
last VM might be a 3.0.21 flavour, we transitioned in that time  
period from a classic powerpc/68k VM to carbon based powerpc/68K VMs  
to Mach-o non CFM os-x only VMs.

Perhaps I'm missing something.  But I get the idea that you think you
have to use a Mac.  Squeak runs on other platforms including Win32,
Linux, etc.  Am I overlooking something that requires that you run on a
Mac?

Dear Ken & John,

The reason I'm using Macintosh is because that's what I have at home.

In answer to John's question, yeah, it's 68k. And I know I *should*
upgrade, if your figures are true for 20 / 30 pounds for a G3, then I
will do so quite soon.

The reason, however, for wanting to work on my ancient machines was
that I wanted something that would work simply and not have major
RAM/CPU requirements. (Of course things have changed a lot since I
last bought a machine.. and this is only a test...)

Oh and I think the morphic-less Squeak-68k VM/shrunk image would be
very useful. I mean - it's not about constructing a GUI - it's about
utilising the sound recorder program to respond to input sounds.

Regards,

Russell

Ok I've posted to my FTP site a SIT and ZIP file that contains the  
mini image that Dan made.

miniImageFromDanIngalls.sit and
miniImageFromDanIngalls.zip

I think they are MVC only tho.

plus the last two 68K Squeak VM's I build for internal usage a few  
years back.

Squeak VM 68K68881NPLUGIN.sit   which is a 68K version with 68881  
math logic (extra feature)
Squeak VM 68KOT 3.0.12 Opt.sit  which is a 68K version with the new  
TCP/IP primitives that used Apple's Open Transport. (extra feature)

I'll have to look when the last 68K version was, not sure if was 3.0  
or was 3.2
