I'm sure all thats in there is a couple of single shots, maybe some SCR's and a 555 timer.



It's more complicated than that. There is an A to D converter that reads the throttle position sensor, a ROM containing a set of digitized advance curves, a timebase oscillator, a number of counters, and some embedded processor to run it all.

You may be in luck though. There was a batch of bad igniters (official Triumph service manual terminology) and Triumph issued an unannounced recall to replace them free if they failed. Yours might be one of them.
