I do not know much about this unit, though the person who owned it purchased it brand new back in the 80's. He told me it worked, though he never used it much, or very little.
I did plug it in, hooked it up to a TV to use as a monitor, and key pad seemed to work. I did not study it enough to learn how to operate it.
