i may have found previously undocumented clone mac roms
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
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
this is a screenshot that i believe to be from the Mac 512 retail ROM (it says "Insert the initialization disk" in Portuguese). in trying to locate this ROM (the only known dumped Mac 512 ROM is actually the Mac Plus copy) i accidentally found the Unitron 1024's instead.
i can only find the "Unitron 1024" mentioned online in two places:
one is in a posthumous legal study of the Mac 512 case in which it's mentioned as an addendum
the other is a supposed MAME driver for which any rom i've found are just... mac plus roms.
i actually found two roms, one larger than the other, but so far i can only get the second one to do this
@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.
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
