Components: Help With Photo

[Caliban]

Can anyone identify the two (literally) black boxes in the bottom photo of
site http://www.gcw.org.uk/rover/igniter.htm ?

This is a photo of the "guts" of a 1991 Honda Civic ignitor (a.k.a. ignition
module and igniter).

My guess is that one of the black boxes is an NPN transistor. The other may
be a signal converter. But I could be way off. These guesses are based on a
lot of reading about car ignitors and the following two schematics:

That at http://www.markl.f9.co.uk/howto/electrical/igniter/igniter.htm .

And that at the bottom of http://www.rustpuppy.org/ignition/Ignition1a.htm .
The latter is a General Motor car's ignitor etc. schematic. It may at least
resemble the Honda's and be helpful.

Comments on the other parts are welcome.

The 8-pin DIL SMC is a Telefunken (TFK) U2226B. Has anyone
got a description and pin-out for this device, please?

Thanks
