Multiplexing Nixies

I have a 3.5 digit DPM at my elbow I've written about recently that is non-multiplexed (Buroughs tubes FWIW), and a bare PCB I picked up many, many years ago at Dayton from what was most likely a calculator, sporting 10-12 Nixies (and a neon bulb minus sign) with all the electrodes wired in parallel and the envelopes (plates?) run off the board independently - obviously a multiplexed arrangement. I'm entirely willing to entertain notions that there are multiplex-compatible and non-multiple varieties of Nixies, or that care must be taken when designing a multiplexing timing circuit, but I am certain that in many if not most calculator designs, the Nixies are multiplexed. -ethan
