  Idle curiousity: under what scenario do you have

 Hand-assembled and entered, using my trusty Monitor II SPS manual by

 Are there any guides for writing 1620 assembly online anywhere?

A pen works well, but you can erase if you use a pencil. Finding the
coding sheet  could be harder ... same with a keypunch operator. :)
