How much a brazilian mac clone is valued?

Jason McBrien wrote: That is an extremely popular misconception, even among those who actually lived through the infamous "reserved market" policy. Due to the huge foreign debt crises, all imports were banned in Brazil at that time: from cars to chocolate bars. What was unique about computers was that in addition to imports being illegal, foreign companies were forbidden from making micro or minicomputers locally (either for local sales or for exports). Long established companies such as IBM and Burroughs continued to make their mainframes. It wasn't the industry that I would have liked to see, but since the whole world standardized on PC clones not as much damage was done as I had feared. In retrospect, I see that the lack of venture capital and the huge economic turmoil created a situation where all of the reasonably funded companies had people from outside the industry in charge. If you want to imagine how bad that can be, think of what result you would have if you made someone from Pepsi or Nabisco president of a US computer company ;-) Another negative factor was that the rules were made for minicomputers and didn't take a third party software industry into account. Copyright was only extended to software in late 1987. With nothing but piracy (importing software was illegal, but copying it was not) a clone has a tremendous advantage over an original design (like the ones I worked on). Brazil had a very weak semiconductor industry, with the bulk of it being one small factory by Texas Instruments and another one being built by Ford. The government killed that off, in exchange for promises of private investment in locally owned factories. That didn't work out well (Brazil has never had a semiconductor factory since) but at least the "no import" rule was never extended to components. But in terms of revenues, the local industry did grow from scratch to an impressive size by the end of the 1980s. A lot of companies were killed off in the increasing economic mess, so practically all that were still around when the reserved market policy ended in 1992 are still with us (another popular misconception is that in 1993 the foreign companies swept in and killed all the locals). Even most collectors are probably not interested. As for numbers, Unitron never got the permission to sell since Apple applied government to government pressure to keep that from happening. There is one Unitron partner who likes to give interviews saying they had a warehouse with 300 machines ready to ship. I really doubt that and have indications that the actual number of prototypes was below 60. But since this was an active development project, there were many variations. One was the "Turbo Mac" which used the PAL equations I designed (not reveresed engineered as many texts claim) instead of the Apple ones (cloned through reverse engineering), as I described in http://www.merlintec.com/lsi/mac512.html There were variations with two internal floppies (like the link Alexandre gave), but most had just one like the original Mac. Some floppies didn't have the mechanical eject button, but most did. A few had black keycaps and mouse button, while others are closer to the original in color. Almost all have EPROMs copied from the Apple ROMs, but a few have an expansion board with RAM that is loaded at boot time and which runs the software that Rainer Brockerhoff was developing. All of the Unitron boards, as far as I know, have a socket for the SCSI chip (like a Plus) but it is unlikely that more than one or two prototypes had the actual chip and the software to use it. I saw one version which had an external 9 inch monitor and looked like a tiny PC. When the analog board of my Unitron machine went bad, I had to take it apart anyway and so took some pictures of the inside.
