The First Macintosh Clones
Apple's strategy of suppressing clone development was successful. From 1986 to 1991, several manufacturers created Macintosh clones, including the portable Outbound; however, in order to do so legally, they had to obtain official ROMs by purchasing one of Apple's Macintosh computers, remove the required parts from the donor, and then install those parts in the clone's case. In 1986, Apple made a deal to sell discounted Macintosh computers to Dynamac for conversion. In 1988, Colby Systems, which had previously produced their Macintosh-compatible laptops on a trade-in basis, began selling them to Apple dealers who would then fit motherboards from their spare stock.
In the 1980s, Brazil's military dictatorship instituted trade restrictions that prohibited the importation of computers from overseas manufacturers. A Brazilian company called Unitron (which had previously produced Apple II clones) developed a Macintosh clone with specifications similar to the Mac 512K, and proposed to put it on sale. Although Unitron claimed to have legitimately reverse-engineered the ROMs and hardware, and Apple did not hold patents covering the computer in Brazil, Apple claimed the ROMs had simply been copied. Ultimately, under pressure from the US government and local manufacturers of PC clones the Brazilian Computer and Automation Council did not allow production to proceed.
