    Duo 210/230: fancy artwork on early PG&E chips?

    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...

    unirom: an Old World ROM info dumper

    This is a small command line utility I've been working on occasionally for as long as I've been emulating Macs in MAME (that's 2009). It dumps out the Universal tables from a ROM so you can see what machines a ROM will recognize and some basic info about each machine. Not all ROMs can actually...
