Citroen Ax Gt "Quick" at the time, rather than fast. Used reliable 1.4 engine in a body that weighed about the same as a paper napkin.
Citroen Visa I had a friend who had the GTI version. In order to squeeze the Peugeot 205 1.6 unit into the Visa, they had to increase the wheelbase. Something that Citreon decided was only needed at the front, the rear wheelbase was a good 6 inches thinner. Quite a hilarious car. But akin to driving around in an origami car, with suitable thin metal panels.
Commodore Amiga The A1000, A500, A1500, A2000 and A600 all had the 32-bit 68000 processor. But it had a cut down 16bit bus architecture. Hence the 16/32bit description.
The A1200, A2500, A3000 and A4000 all had full 32bit architecture. They had 68020, 68030 and 68040 processors.
Commodore 64 GEOS, the GUI for the Commodore 64 came out in 1986. The Apple Macintosh was out in 1984. So the article is wrong.
The disk drive option was as expensive as the computer and most people used the standard Commodore Datasette 1530 tape thing.
