Any Lisp screenshots?
I believe fibonacci is a required exercise for occations like this.

Hi Al
Many programmers use the +5V to switching boost for programming voltage because
the needed level has a low current load for the programming level. The
additional wire might be for a negative level, such as RS-232 or DRAM. These
are still things that can be traced out with and ohm meter and

first, a big "thank you" to all of you who support me with my attempt to
