Ok, I do seem to recall the tacho dropping like a stone. Friday night I'll
run the engine in the garage (with the doors open) till the fault is
manifest. I'm expecting it to be the pick-up rather than the coil. I'll also
see if
I can work through the advice on the MG Cars bulletin board and put my
multimeter to some use.

Unfortunately, the tach is your best diagnotic tool at the moment. Since the
tach is monitoring pulses at the coil, if the pickup ceases to turn the coil
on and off, the tach needle will drop like a rock, even though the wheels
are still turning the engine. OTOH, if the coil stops generating the
high-voltage sparks, the tach should still register, since the low-voltage
side of the circuitry is still functional.
