Need a vintage CT7001 clock chip
If anyone has one for sale or trade or knows where I can get one, please reply to ruteng1 @ att . net
That is an old Fairchild / Cal-Tex part number (circa 1978).
IF you find old Radio Shack blister pack parts, look for part number: RS1756 -- that was the Cal-Tex clock IC.
Here is an old Datasheet / Application note for this MOS/LSI Clock Calender
Can you use the NTE2060/1 ??
These do not have multiplexed outputs.
Nullius in verba
I have a Mostek MK50252N Radio Shack 276-1751 with data sheet. Is that close enough?
Not really. The two parts are vastly different and not interchangeable.. The only thing they have in common is that they are both Digital clock chips.

thank you all for you interest and suggestions. I do need the CT7001 only as it is replacing a blown one in an old clock I made back in the 70's
