Inspired by golden_crystal
(http://goldencrytal.free.fr/M68kOpcodes-2.3.pdf)

I try to map the 68080.
It is not complete, work in progress.

Disclamer: this is the work of an individual not related to the apollo-team.
Just trying to make the information more clear (mostly for myself)
with the use of color.

tab_1_68k
Is the base 68000 with colored later instructions, privileged and some 080.
no line-F.

tab_2_fpu

tab_3_p
procesor specific

tab_4_apollo
all apollo 080 should go here.

tab_5_dc.w
ammx read as dc.w

tab_1_68k & tab_4_apollo is the focus.
big:

sources used:
