Yeah cars, not out of scope and lots of them.
Currently MAME has a driver for the talking car
which used the speak & spell chip.
I scraped up as many roms from car ECUs as I could find a few years ago due to the emissions cheating going on by VW, here they are on archive.org
Now I don't know the arch of all of these dumps, I know bosch ECUs use an MPC555
which is PowerPC and that Nissan went SuperH
In this thread I hope to collect as much tech information about car ECUs so they can be documented for the future and for people to be able to fix their "vintage" cars just like we can with arcade boards.
Any help in sorting these dumps is appreciated.
