the Mac 512 was shut down not because the case looked like a mac, not because the analog board was a carbon copy, but because the unit that Apple somehow managed to investigate for themselves during development contained a copied Mac Plus ROM. however, Unitron's argument was that that was only being used for development purposes and the retail version would contain a reverse engineered rom. at the time, there was no law against that in brazil
development documents. this mentions the rom is for both models ("Mac512/Unitron 1024") but i don't think the sources in them are complete
the source i found has several floppy images, but also some folders that seem to be from different floppy images destructively extracted into a FAT type system so some of it might be lost
@mavica_again I'm going to have to reconsider my avatar on here
@mavica_again I see a bunch of stuff pull up on DuckDuckGo and google?
@mavica_again ah, took "two" as literally two results.
this seems to be a ROM for a later Unitron clone, the "Unitron 1024" which work was started on after the US govt threatened and forced the shutdown of the "Mac 512" project. supposedly the Unitron 1024 wasn't going to look like a macintosh, in an attempt to appease the government, but it also got shut down regardless
