MA1026 clock/temp module

Does anyone know a source that might have an old MA1026 clock/temp
module? I think it was made my National Semiconductor. These were those
modules that had an LED display and a bunch of contacts on one edge. You
added a transformer and a bunch of switch and got a nice digital alarm
clock. This version also had a temperature sensing capability.

I have one I bought from Radio Shack in the early 80's and made a clock
out of it. I even had it control a relay to turn a stereo system on to
wake me up! It died a few years ago (display is scrambled.) All obvious
voltages seem OK. I would like to try and revive or replace it, but so
far, I haven't found much information other than an Italian site that had
a partial datasheet scan (I still have the full Radio Shack datasheet.)

Yeah, I bought a bunch of these from Digi-Key when they first opened back in
the 70's. The clock modules were as handy as a pocket on a shirt. I built a
few digital clocks with them and gave them away as gifts back when
electronic digital clocks were "cool'. Not those goofy flip card things . .
although if you look thru eBay, those flip card things are fetching pretty
high bids! Can't find a single one in the junk box, guess they all got used
up. Was the chip they used a 5314, is that right? Seems like there were
three chips in the family. 5311 was the bare bones one, and 5314 had all
the alarms, sleep timer etc.
