Interesting notes from the seller, mentions slight ghosting. The clock-chip
does the multiplexing, though it was probably intended for LEDs which dont
have requirements for blanking time.
The PC board is typical of consumer products: single-sided phenolic. Even
do-it-yourself PCB kits used
Indeed...

The Panaplex display most probably sees the whole voltage span 56V + 137V =
193V, the circuit is just built this way to provide lower voltage to the
MK5017 and as bias voltages for the transistors driving the display. Have a
look in the book I mentioned above, if you haven't done so already, on
