i'm using gschem for linux, which is part of the gEDA suite.

i've converted it to b/w and rescaled it - should be easier to read now.

thanks for the info, but i want to stick with a separate chip design.
partly because i don't want to learn a whole new thing to get this project
done, and partly like i said because i want it to be possible for someone
else to build it from the plans without any fancy equipment - i'm talking
about people who have hardly any electronics knowledge but can follow
instructions to assemble a circuit on stripboard.
