Good point. Just as TTL needs to be stockpiled, I think we should be in a habit of archiving virtual machines containing development software installed in a compatible operating system, so the software can still hopefully be used long after the original machines are obsolete. Much like we often use SIMH now for maintenance tasks to help bring up old machines that no longer live in an ecosystem of similar machines. -- Mark J.
