LisaList2

...Well, maybe not.

Was there a Pepsi system? The only thing called that was the floppy interface board for the Lisa 2's, no?

Wasn't "Pepsi" the code name for the machine with a built-in hard drive? IIRC they hired a manager who previously worked at that soda company, and he created this project.

Right John Sculley, who became the CEO, but that machine just sounds like the Lisa 2/10 to me, I don't think it was a separate non-Lisa machine by that code name as far as I know: https://en.wikipedia.org/wiki/List_of_Apple_codenames (I absolutely could be wrong here.)

There was the bouncing pepsi demo mentioned here: https://www.folklore.org/StoryView.py?project=Macintosh&story=Bouncing_Pepsis.txt and you can see it in action here: https://www.youtube.com/watch?v=FzDB16Zgodw

(There were also Whopper and Big Little Machine as alternates to the Lisa.)
But yeah, the only thing named that was the "lite" controller for the Lisa 2 as far as I know, and I'm not 100% sure on that either as it was renamed to Lite.

Wasn't Pepsi the codename for a Lisa 2 with 400K Sony drive?
