Hello everyone,
Drdave recently contacted me about the sounds and bonus countdown on the Cheetah in the video I posted many years ago here:

His sounds like this:

My Cheetah is a bit different from most of the others I've seen over the years; it has the blue cabinet (as opposed to the far more common black), purple and blue bonus inserts, and different (aka way better!) sound.

Anyway, Dave convinced me to dump the roms and send him the files, which I've now done. We're calling these "proto" roms, although I'm sure that's a misnomer. Scott C. looked at them and he says they're quite a bit different from "production" roms, although I can't comment on specific differences other than the sound and bonus countdown.

Anyway, I'm going to send these to the IPDB to have them posted, but in the meantime if anyone wants the files, shoot me a line and I'll email them. Steph at Hobbyroms.com also has them, if you want to order them on 2732's or whatever.

Interesting. My Cheetah looks and sounds like yours. Blue cabinet and the sounds are the same. I did a pf swap with a better playfield and noticed that the bad playfield has blue and purple bonus inserts whereas the better playfield are green (as well as a few others that were different). The second Cheetah video you have does have weird sounds compared to mine too.

Interesting. I also have an earlier blue cabinet with I guess the earlier sound roms. I've never heard the later version sound roms until now. Didn't know they existed. I think I almost kind of like the later version sounds better.

Well, let's call these "blue cabinet" roms rather than proto.

The roms available currently on IPDB and elsewhere are "black cabinet" roms. I installed them in my game once a long time ago and didn't like the sound change, so I went back to the originals. The blue cabinet sounds are among my favorite in pinball and a huge contributing factor to me keeping this game around for as long as I have. I only have space for three or four machines, and Cheetah has been one of them for nearly a decade.

Can anyone shed some light on why there were two "versions" of this machine produced?

Can you send me a copy too please?
I'll drop them off at Gaston for adding to PinMame.

The sounds for the blue cab game sound pretty similar to Flight 2000. I wonder if blue cab Cheetahs used leftover cabs from Flight 2000's run?

[edit]: Hmm...maybe not. IPDB indicates Cheetah was produced in June 1980, and Flight 2000 was produced in August 1980.

[edit]: Actually, maybe there is some merit to that--Cheetah was produced from June to November 1980, and Flight 2000 was produced from August to December 1980. So maybe there was some crossover because of parts availability just to keep the production lines rolling?

[edit3]: I wonder where the serial numbers fall for blue vs black cabinets.

Beautiful game Mike!

Here's a video of a Flight 2000 with good audio for comparison to the sounds on the blue cab Cheetah (caution--video is loud, so turn down your volume)

Well, I just did a diff comparison between the blue cabinet ROM files and the Flight 2000 ROM files, and there was very little in common. So, it's safe to assume the Flight 2000 ROMs were not simply reused in Cheetah, even though the sounds are similar.

Comparing the blue cabinet and black cabinet ROMs, U1 is very different, U2 has a couple small differences, in U5 the blue cab file has a few more lines than the black cab U5 file, and U6 has a few differences but mostly is the same.

Now I'm wondering if there are any rule differences between the two sets of ROMs.

Fascinating stuff. I'd also be curious to see if there are any rule differences, but I don't think there are. I've played both and have never noticed anything different, as far as the rules are concerned. But then again, I wasn't really looking for any differences either.

The blue cabinet roms have been added to PinMame.

cooke, great find!
Is there any chance you can post a clear picture of how these ROMs were marked (label markings) from factory?

The details are interesting from a documentation perspective.

Thanks in advance.
