This is a vintage Intercon InterFont electronic cartridge, model WPG-PL-12E. The cartridge is made of beige plastic and features a multi-pin connector on one end, designed to interface with compatible electronic equipment, likely a word processor or printer. The label indicates it is a 'SERIES 721 IB PICA/ELITE (EQUIVALENT)' cartridge, offering various font styles such as Medium, Bold, and Italic in 10 pitch and 12 pitch. It was manufactured in the USA by Intercon International Associates, Inc. in 1984. The cartridge appears to be in good condition with minor wear consistent with its age. Functional: AS-IS / UNTESTED. I do not currently own a compatible vintage laser printer to test this hardware, so its functional status cannot be verified. Pin connections on the edge connector look clean.
