As you aware a well known chip made by MOSTEK during 1970's were very successful and then it was purchased by United Technologies Corporation in 1979 then it destroyed by bad management and greedy.
Nowadays, MK-5017 clock chip (later added with calendar feature) was impossible to find in any vendors and so many eBay purchased and destroyed because they had lack of experience in electronics. Same with Beckman Sperry SP display series (Panaplex Neon Display) were so popular during that time. Nowadays, no one to have a remanufacturing that wonderful displays with easy to read even far better than LEDs.
I struggle collected Beckman Sperry SP series and collected electronic components. But no luck with MOSTEK MK-5017AB or BB chip.
I wonder if you may have more experience to create PIC to provide a printed circuit that have pin to pin compatible with old MK-5017 and compatible to drive circuits and run three SP-352 displays.
In fact, there are three different versions of MK-5017 during that old days were:
MK5017 P AA - Alarm Clock
MK5017 P AN - Clock Radio Alarm
MK5017 P BB - Calendar Clock
Hopefully, you may able to create "clone" with PIC microcontroller to act exact what MK-5017 series provided to support the circuits.
Thank you
