The address lines of EPROM accept output of the hour decade counters and the eight data output line of the EPROM will go to the 74LS247s as data. One additional address line of the EPROM will act as 12/24hr selection via a switch. Changeover can be done at any time with no concern of any logic problem.
Question is whether he can find a way to program the EPROM with the correct data. With so little data(48 bytes) to enter, it is doable via some switches on a breadboard.
How do I make a simple eprom programmer to accomplish this task? What would the code (48 bytes) be?
