I'm a huge fan of TIM, and I own just about every shape and form of everything related to it, with the exception of some console-only stuff. I would be honored if GoG could make use of any of this information, or if there are any resources I could provide them (as a lot of the stuff mentioned here is pretty rare).
I haven't bought this on GoG yet, but based on available information, there are some things I can assume about it. TEMIM and TIM 2/3 have CD-ROM versions available that add enhanced music and speech, and from the filesize, the enhanced music has definitely been axed, and possibly the speech too.
==The Even More Incredible Machine notes==
Here is a brief, fair-use protected sample of the enhanced audio from TEMIM CD-ROM:

There's one technical issue with this, though. Being a DOS game, one must emulate this through DOSBox, but after finishing one level, Professor TIM's voice starts sounding like a broken record. Through much trial and error, I was able to find a solution. In the DOSBox config, under [sblaster], set "sbtype=sb1". The default of sb16 will cause the broken record problem, but sb1 works perfectly for me.
==The Incredible Machine 2 / 3.0 notes==
This pack seems to include TIM 3.0 but not TIM 2, and is missing the redbook audio. Contraptions has the same tracklist, and it's in mp3 form, so you should be able to hear TIM 2/3's enhanced music by playing that game.
As far as I can tell, TIM 2&3 are exactly the same game, with the sole difference that TIM 3.0 is ported to Windows and has an interface consistent with Windows paradigms. This is actually a disadvantage. TIM 2, being a DOS game, can be emulated with DOSBox, which means greater control over the system's environment. There's no simple way to make redbook audio work with a DRM-free Windows game, but with a DOS game, you can just configure DOSBox to mount a CD image.
So, I would consider TIM 2 to be the more desirable version.
==Sid & Al's Incredible Toons==
This is a spinoff game with the same gameplay as TIM, but with a cartoon motif. I think it's a must-have for any TIM fan. It's a floppy game and runs on DOS, making the matter of running it trivial.
But, there's also an enhanced CD-ROM version called "The Incredible Toon Machine." This version runs on Windows, has redbook audio, an intro FMV, and before each level, Sid and Al, fully animated, will walts onto your screen and narrate your objectives as they mutilate eachother.
Here's the FMV on Youtube:

Getting the redbook audio would be tricky, but worth it IMO. I guess a music CD image could be provided, with instructions on how to burn or mount it. The one gotcha is that if you have more than one drive, the disc must be in the drive that is lowest alphabetically. For example, if you had a Blu-Ray drive at E:, a DVD burner at F:, and a virtual drive at G:, then you would need the disc in the Blu-Ray drive.
All that said, the DOS version does have a certain intangible charm, so I wouldn't discard it in favor of the enhanced Windows version.
In summary, I think the ideal TIM Mega Pack would include these:
* The CD-ROM version of The Even More Incredible Machine, configured to run through DOSBox
* The CD-ROM version of The Incredible Machine 2, configured to run through DOSBox
* Sid & Al's Incredible Toons, configured to run through DOSBox
* The Incredible Toon Machine, with the FMV and speech files
* A CD image with the above game's soundtrack on it, that customers can burn or mount so the game can be played with redbook audio
With the possible exception of the last item, and as long as there aren't any rights issues that would get in the way, I know it's feasible to implement all of these according to GoG standards. And even if the CD image isn't, I still believe it would be better to offer it as an unsupported bonus than to not offer it at all.
I do own legit copies of everything described above, and if there is anything I could do or provide that could help make these ideas reality, I'd do it without hesitation.

Totally agree. It should also include the original TIM -- even if most puzzles from it were reused in the later games it still has some nostalgic value for the fans of the series.

I'd be perfectly happy if The Incredible Toon Machine was sold separately, but it should definitely be offered.

Actually, all of the puzzles from the original TIM are included in TEMIM. TEMIM is the original TIM, but with more puzzles, more parts, and more music.

Yeah, I agree with you about TIM 2. From what I remember, TIM 2 has a much nicer interface. The Windows 95-era interface of TIM 3 is just ugly. And if it's missing the CD soundtrack, that's really a dealbreaker for me. That soundtrack was great.

Damm man, obviously you are.
I've never played the game, but I know what it takes to know that kind of detail about something. If it's THAT cool, I'm buying it now...

I agree. As excited as I am to see these great games on GOG (and I will definitely buy them), I wish they had made the pack a little more complete. I already own the TIM2 CD, but I'd love to have the full CD version of TEMIM and The Incredible Toon Machine.

Heh, ironically sound problems with TEMIM aren't exclusive to DOSbox at all. I recall the whole reason I never played very much of the CD version on my old 386 desktop was because after every level the music would gradually get louder and the sound effects would get quieter. It got very unplayable very quickly.
Personally TIM3 is the one I most hold a soft spot in my heart for since that was how I was introduced to the series, but I'll admit TIM2 has its charms. Unfortunately either it's not very DOSbox friendly, or the game's got horrible loading time issues. I never played it on its native hardware so I don't know, but waiting 2 seconds each time you click on something or move a puzzle piece isn't very conducive to fun.
What's really a damn shame, though, is having the redbook audio and speech cut from TEMIM and TIM3. I mean, the midi music is fairly nifty too but not nearly as nice to have playing while you're trying to figure puzzles out.
Don't drop a hog in the parts bin, ye'll be forever tryin' to find it! Huh-huh-ho!
I mean, GOG's already pulled a trick with several of their releases wherein they chuck the contents of the original game disc in with the game files as a ".gog" file and make the game read from that, couldn't that be applied here too?

TIM2 works perfectly on DOSBox for me. No delay when moving puzzle pieces here.

I just purchased the pack today and was very disappointed when I learned the objective narration wasn't included. Turned a fantastic purchase into a decent purchase. Still nice to be able to play these games again.

Sid & Al's Incredible Toons, is by far the best in the series, so it's sad it's not included.
Then again, i wouldn't mind buying it as a standalone game.

Totally agree, I'd even be ready to pay extra for it

Gamecard?
It doesn't.

I found the reason why TIM2 was not included - possible licensing issues.

Few music tracks present in TIM2 were not included in TIM3. For example, one of them is known as "Space Theme" - 2001: Space Odyssey main theme. I know that, because I found TIM2 on one of abandonware websites and tested it myself.
