As part of research for the upcoming addition of all of the 68030 and 040 Duos to MAME, I ran across this page https://www.dobreprogramy.pl/@macminik/powerbook-duo-best-of-both-worlds,blog,39291 with an interesting photo of a Duo 210/230 logic board. The PMU chip doesn't have the normal text-only markings, there's what appears to be line art of a power station with lightning bolts coming out of it. Does anyone have a Duo 210/230 where the chip has those markings and can post a higher-res picture? I know that sort of line art was common internally at 90s Apple, but I haven't seen it out in a production machine before.
