The POWER C software made by BetterWorking from Spinnaker Software
Corp. has a Copyright Date of 1986 on the box.

The box says it's a "disk based true C language compiler for the
Commodore computers.".

Is that the compiler You were thinking about?

And speaking of the Apple ][ , I've seen a C=64 PRG that some Apple ][
BASIC Programs could be ran with.

I can't remember if the PRG was called a Apple ][ Emulator or what.....
