- TAX161 Time Announcer - audio ad. The TAX161 was a 1.75 inch rack mount cabinet full of CMOS logic and relays. It controlled two tape cartridge machines, one holding announcements of even minutes, the other holding odd minutes. When an automation system closed a start relay to run a time announcement, the appropriate cart was played and the EOM closure routed back to the automation. If a minute was not announced in a particular minute, the system advanced the cart so it would be correct the next minute.
