[Coco] (OT) Radio Shack Kits

[PaulH]

I built a couple of these clocks back in the day.  I was interested in building a few more, but RS had begun
to discontinue the chip, so I went around to several stores to purchase some backups.  Turned out that was
a good move since the chips seemed to go faulty in about 4 years of use. 


 IIRC, the 7001 was made by Fairchild and it lost the chip mask to continue production. 
 Fairchild p/n: FTK0400 (FCM7001)


So I have a few good chips left which should last to the end of the decade.    -ph

While this is not CoCo specific, it is Radio Shack related. Years ago 
(many more that I want to admit) I purchased the CC Board kit from Radio 
Shack to build the Clock/Calendar/Timer which used the RS7001 (Part # 
276-1756) and spent almost a year building it. Now that I am way older 
(and hopefully better at soldering) I'd like to do it again.

When I search the web looking for a kit that uses this chip (since it's 
been 38+ years since it was sold by Radio Shack) I have no success. Does 
anybody have a recommendation on a digital clock/calendar (8-segment 
LEDs) that uses this chip or a very close approximation?

The kit used the MOS/LSI chip 276-1756; the 277-109 PC Board; the 
277-108 Universal mutliplexed LED board

Thanks
