1977 (?) - RT68
1980 - OS-9/6809
1983 - OS-9 ported to 68000
1989 - “Portable OS-9” written in C (OS-9000) for X86 and 68020 and above (or was it 030?)

…then sometime in the mid 90s it was ported to Power PC, and all hell broke loose with StrongARM, Sparc, MIPS, SH-3, SH-4, and probably others I have forgotten. All of those were the portable C version, OS-9000.

For the longest time, you could request a “demo” CD of OS-9/x86 … “hidden" on the disk was a zip (or .tar, probably) file that contained the full command line Ultra-C compiler ;-) At that point in time, all development was done on Windows (Unix had been dropped). That zip file was for the hobbyists, as it was not time bombed like the Hawk IDE’s compiler for Windows was. Anyone could snag that demo CD and get it up and running and be coding in C.
