No, but since a return can be as much as 18" and the head weighs about a
pound, it can seriously shake the stand its on to kindling in 20 minutes if
its not had the screw in every nail hole treatment, along with some

I had forgotten that. I should get that, but the pc it would have to work
against runs linux. The only windows around here is a 20Gb XP install on my
lappy, kept only for testing purposes if I have to take it to CC or someplace
for service. It no longer autoboots XP although it is in the boot menu.
As CC has announced to close the other 500+ stores (bankrupt) my extended
warranty is probably toast, and I will probably blow that partition away the
next time I update the linux on it.
I wonder if wine can run your pc stuff? OTOH, I have a 1GB drive on the coco,
so all I really need is a working comm link to it. Cabling is already there.
