Wanted - 7 segment clock chips CT7001 or AY51224
Many years ago I built two 7 segment clocks with these chips. Has anyone got any floating around in their junkbox? These chips are not made any more, or any equivalent as far as I know, unless anyone can advise me otherwise. Both these chips had multiplexed outputs and used transistor drivers for the displays.

OK, thanks Maurice, I will wait to hear from you further. Any other clock chips will do, they do not have to be the ones I specified as long as they have 7 segment outputs. NTE2060/1 are fine but they do not have multiplexed outputs and these are also getting difficult to find. I could use BCD chips and then BCD to 7 segment decoders but this involves too much effort.
