I would just like to say that the 68nf capacitor does work with the 16mb Jaspers as well as the big blocks. I had positioned my wires away from the coils as in the guides but made no difference, boot time was between 10 seconds and 2 minutes more often around the 2min area. Fitted the capacitor between GND and A and hey presto boot times now between immediate and 10 seconds. Well pleased with it now.
