I decided to give my very old Apple ][ model an upgrade by adding a Monitor II and Disk Drive II! Very simple prints - check the colors from the pictures. Take care in applying only a little glue to the monitor screen frame when you glue it to the monitor body, as you want to create a nice clean channel for the paper screens to slide in and out of.
