Hi Ron - seems your brain also does "cool computing", letting you stay that calm. ;-)
Well, I do understand the frustration, but I think nobody gains anything if this thread leads to even further frustration - i.e. also on Ron's side.
Unfortunately, I'm sometimes myself quicker at posting than at reading carefully and thinking before, too, but maybe it would be more benefitting if this thread would get an update just weekly? Even Ron can neither perform miracles nor does he have a voodoo puppet of Mr. Dellert to remote control him from Rotterdam.
Of course no-one will be surprised if I say this, but I do so anyway: I think it's great by Ron to sort this out (especially since he really has already enough other tasks at hand in parallel), and I wish there would have been a "Ron" back then as well, when I had myself an Amiga in repair at another place many years ago.
