early 10V Turbo ignition signals

[Christo Atanasov]

May someone give me Voltige/Time diagram of ECU trigger signal Vs Ignition Coil primary voltige.
I need this to detirmine what tipe of transistor is ignition driver of this early 10V turbos (2 pins connector)
In fact if Colector of this transistor is grounded (TO-3 body always has colector on tab) it must be some P-Channel darlington, but whole last night I searching in internet info for high voltage P-chanel darlingotn and there is no such element.. Most powerful P-channel has Vec max 160V which is not enough.
Now I think that may be this hitachi igniter on original coil is maybe a combo of PNP and NPN transistors.
