That’s what [Scott] did , and he put it in an enclosure that would look right at home in a late 70s engineering lab. The impetus for this build was [Scott]’s discovery of the KIM-Uno , a kit clone of the KIM-1 using an Arduino Pro Mini. The kit should arrive in a few weeks, so until then he decided to see if he could cobble one together with parts he had sitting around.
