Michael Woodley reported: "At the time, there were three 6502 versions of FSII. There was one for the Apple II, one for the Commodore 64 and one for the Atari 800. When the the Atari ST and Amiga were introduced (which ran the Motorolla 68000 processor), new versions were released for those machines, for the Tandy and for the MacIntosh through Microsoft. The versions of FSII for the 6502 processor DID have solid filled graphics not just wireframe."
