"Program" a DAC??? Why not just get one with a parallel interface and
write to the silly thing?

Bit banging into the serial DAC from the parallel port is very simple also.

For example, one I remember from cave-man days
is the MC1488, which just has 8 input pins, and when you write your
data to it

That was in the old good cave man days. In our days, you will need a
kernel level driver to access the PC parallel port directly. BTW, there
could very well be no such thing as the parallel port at all :-)

Modern OSs like to own the hardware, which makes hacking difficult.

I'll leave the company name out of it, but we did a bit banging
solution using the dos found on the windows boot disk. I thought it
was cheesy, but not a particularly bad idea. Somehow a virus got on
the boot disks we gave to customers. At that point I thought it was a
bad idea. ;-)
