68000, the design of the Amiga began in 1983 and The A1000 was available in 1985.
68020, first used by Commodore in the A2620 turbo, which was available in 1988.
68030, launched in 1987, implemented by Commodore in the A2630 in 1989, then later in the A3000 in 1990.
I agree, not available on day 1, but let's not stretch the dates needlessly.
Here's an early turbo from 1986 with an 020 by CSA: http://amiga.resource.cx/exp/csa1020
