| Taʼrif |
English: A digital clock/calendar built of TTL parts, designed in the late 1970's as a real-time clock for a process control computer. Because of the high current draw, the standby power was a 12 V 8 AH lead-acid battery. The photo shows some loose TTL chips and a well-known manufacturer's catalog of TTL parts.
