Well, seems as if I’ve done it again. My apologies to fergycool and to Ranier. But, as the Forum software still will not allow me to Split Topic > Select posts to split I then created a new topic: Hot Mini (Thermal Pad) and sent related posts there using Split topic after and including this post. Problem is that two posts that needn’t have gone along DID. I was able to delete Ranier’s post (my sincere apology) but Forum software won’t allow me to delete fergycool’s as it IS the FIRST post under a new topic.

So with again with all my apologies, here's the content of those two posts that should have remained under this topic.

And looking at the red-outlined area, the white-ish looking areas are where the thing remained “stuck” to the processor (green dots). While the smoother, dark grey areas (yellow dot) might represent where actual heat-exchange contact was no longer in effect. (i.e. baked and separated.)

I removed everything and very carefully also tried to clean the top of the CPU (although not too hard!).

Again, it would have been interesting to note the exhaust air temperature of your mini before replacing the paste. But big congrats on a job that many simply choose not to attempt!

Thanks. The exhaust air temperature was not too hot before, although I this was just tested with a wet finger rather than a thermometer. Now you can barely feel any heat at all.

Forceps are in my computer tool box now. There's two other pairs in my fishing box anyway :-)

Thanks again.

Thanks for this excellent tutorial!
Clear, detailed instructions and commentary. Helpful illustrations/photos.
I wish every hardware-oriented tutorial was this well done.
My G4 has original paste. Time for some surgery.
Thank you!

For Hot Mini (GPU Thermal Pad) see: https://macos9lives.com/smforum/index.php?topic=7499.0

i believe it should technically be no problem to create your own GUI kits in codewarrior which use GL2 for example so that you can move stuff around with normalized coordinate values and transparency, i am just not sure about making custom windows and boxes.

hoping for modified OS version for the 12" someday

many thanks to everyone for all the good info in this thread!

i wanted a quick way to boot my OS9 partition with a specified fan speed, so i spent some quality time with OF and came up with the following...

a year later, i am putting OS 9 on a PowerBook6,8 which has a different partition setup, and i noticed there is a mistake in my fans9 code. there are two problems:

1. my boot device syntax is wrong, should be " hd:,\\:tbxi"

2. i tried to pass the device to the boot command via typical Forth postfix notation, forgetting that it is one of those commands that parse the remainder of the command line instead of popping from the stack. so the boot device i gave is actually ignored and i guess it picks the first one found. this happened to work on my iBook, not so much on the PowerBook

luckily, there is a more Forth-y variant called $boot. so the fixed fans9 becomes:

: fans9
dup 0 ff between if
    " set-speeds" " fan" open-dev dup >r $call-method r> close-dev
    " hd:,\\:tbxi" $boot
  else
    ." speed must be between 0 and ff"
    drop
  then
  ;

(on my PowerBook i actually need to specify " hd:9,\\:tbxi", which this version successfully lets me do)

I am laughing.
 
I think I remember you relating that Swiss “trade office” story before. And that is truly funny that my oft-now foggy brain remembers that. That bit about Ellen Petry Leanse led me to some blog post of hers concerning Jobs and the Think Different campaign - which I always considered the complete creative brainchild of the ad *agency (that my foggy mind can’t seem to remember at this point). But the creative “guy” behind it was Lee Clow.

And I once belonged to a now long-defunct Mac User Group here back in the 80’s and I know that some MUGs are still around. But good luck finding those old coots.

Now it’s just these young whippersnappers!

Get-offa-my-lawn!

* Chiat/Day ad agency…now TBWA\Worldwide

I am trying to use my Ti with wlan. Works well via modem and wep encryption or free. Now I wanted to use it with a hotspot from my new KaiOS phone. Therefore I open an unencrypted hotspot. The TI can connectto the phone. I can surf via Classilla, but airport is in a kind of loop and displays "searching for status" and 5 seconds later "status not available" and so on.

I can download only files up to 232kB, than it stops …
There are no adjustments possible for unencrypted hotspots at KaiOS.

Any ideas?

Finally got back to this after Wozniattack’s post above concerning the old thermal pad replacement in the G4 Mini. And I finally got a dual probe temperature meter to use for the eventual copper vs. normal heatsink comparisons - so I used that here for my baseline temperature results from a 1.5 GHz Mini. AND since I do not have Dungeon Siege to run and monitor temps with, a comparison with W’atak’s temps is sadly not completely valid for comparison. However when (and if) I ever get around to changing out that thermal pad, the numbers noted below should / could be (with temps taken again after a thermal pad change).

It is interesting (to me anyway) that W’atak’s recorded temperatures of 41˚ & 43.3˚C [106.16˚ & 109.94˚F] are so close to the HIGH maximum exhaust air temps that I recorded back in 2023. http://macos9lives.com/smforum/index.php?topic=5955.msg52638#msg52638

“Initially, all tested Mac mini fan exhaust temps (mini case covers off) here reached 84˚ (maximum) soon after boot and remained there steady. With the exception of two Minis here that quickly went to just above 100˚F almost immediately. [There’s a BIG clue.] Renewed the CPU thermal paste and those temps then matched the 84˚. (And all with no White Case adapter covers in place ~ “naked”.)”

Now here today with a lower ambient room temperature AND the mini’s cover-in-place, the max exhaust temp was only 82˚F (after 30 minutes). So undoubtedly, ambient room temperatures have some bearing on all of this too. It’s still quite “Winter cool” here. When my previous exhaust temp tests were done, the room was 76˚F. (Nearly 10˚ hotter.) And really all under no load other than displaying the desktop on a monitor in millions of colors. Baseline testing.

Anyway, ATAB = Ambient Temperature @ Boot. And I used the T1 Sensor taped directly underneath the center of the thermal pad on the rubber bottom of the mini. The T2 sensor was placed inside the exhaust air vents on the back of the mini. Minutes noted are elapsed runtimes after a cold boot...

I love this "software archeology" ;)

The most advanced thing I ever did in this direction was to give the swiss "trade office" a call, ask for the names of the former owners of the cleared company, and subsequently found them via the public phone book. I even got the permission to give away the software "as is" and for free from them, but sadly never found a user with complete copy and serial.

You're most definitely welcome. I enjoy a good mystery and a possible rare find.

Sadly again, no reg or serial number but “GrabbyWindow MetaPro” might be what you seek. Found via dogpile.com AND duckduckgo.com search engines. Both hits lead to the Internet Archive (as you had already visited). However https://archive.org/details/tucows_294628_GrabbyWindow_MetaPro delivers one to two trial version .sit downloads. The first one is MetaPro v2.0.6 (for OS 9). The second .sit is for OS X which likely means that the first one listed is the last one for OS 9?



AND as the files originated from Tucows, maybe someone there might assist you in tracking down registration and serial numbers? Or even the software’s creator?

You possibly remember tucows from those thrilling days of yesteryear? If so, wait ’til you get a load of their website and current foci. Guess that 30 years can have quite a change over what once was a fledgling concern? https://www.tucows.com/ If it’s even the same company?

So perhaps as the collective we once did, if the Trial Version is a limited, timed-use bit of shareware, we simply uninstalled and re-installed the software - or set clocks / dates back. Unless someone here actually has the software and valid serial number. Hopefully the trial version is not feature limited.

And as with every quest such as this, I tend to discover other things… like the 87-88 Apple User Groups listings .pdf from COMPUTE’s Apple Applications Spring/Summer issue which I’ll also attempt to attach here. Some few of those MUGs might still be in existence today AND someone could have more of what you seek.

Also interesting to search “Ellen Petry Leanse” to see what she might still be up to these days.

Steve Jobs and Ram Dass?
(Ahh, grasshopper.) Be Here Now, indeed.

Well, thanks aBc, this is a first step. It seems to be a trial of the non-pro version. Where did you find it? Any hints what the latest version is?
