They have survived on a "divide and conquer" basis. Watchdog might
have finally broken this down

Unless someone could offer them a tried and tested re-engineered
solution that works. Would save them some of the R&D.

Ah, but they already now have the Mk III PCB which is a completely
different pcb with half decent technology and makes Potterton a tidy
profit

... still doesn't work that well though

The actually functionality of the old boards when they work (which for a
minority of people seems quite a while) is adequate (the boiler makes
primary HW and does not catch fire). The problem must therefore be that
the components are under specified or the manufacturing is lacking.
