High Voltage!

I have been checking out flash voltages at the following website:-

I have got 1 or 2 older flashes but would not risk them frying my Pentax *istD internal circuitry so I would like to ask the group what is the last Pentax Model made that would not be affected by these high voltage old-style flashes? ... Would it be the 'P' series of cameras or the 'A' series or something else?

Thanks in advance to the Pentax User(s) with the answers.

I dont know the answer as to which camera series can cope with high trigger voltages. However you can purchase a Wein SafeSync which will reduce the trigger voltage.
