The first one looks to be 680x0, with each 'x' being a number -- data
registers for the Dx, address registers for the Ax. When I first read it,
it appeared to be somewhere around PDP11, but PDP11 did not have
Moveq (Move Quick), did not have Suba (Subtract Address), and
did not have Byte (.B), Word (.W) -and- Long (.L) extensions.
The second would be something in the *80* series, like Z80 or 8080 or
80x86. The 'de' registered had appeared by the time of the 8086, but
I wouldn't swear it existed at the time of the 8080. I'm going to
guess Z80.
