Hi
Does anybody know a site that has 8086 machine code info.
I’m trying to machine code an Eprom and have lost my
training notes.
I need to make a jump back 53d bytes. If I remember right you
add one to the jump from location, count the bytes back to the
jump to location, convert to hex, then find the reciprocal.
This then becomes the displacement in a “direct within
segment expression”. For a jump back 53d I make it EBAC.
Can anyone confirm this.
Regards
Scommstech.
