As Rick Lawhorn can testify, it's okay to knock the 3675 flat on its back while
someone is using it, it will keep on running! Actually I think that was a 3670
or a 3600, and in any case I wouldn't recommend trying it at home: only highly
trained professionals who know what they are doing can accidentally tip the
machine over without breaking it!
OK ... I'm one of those dangerous professionals ;-)
Geez Dave, this is almost unbelievable. Only certain disk
drives will keep operating with this kind of shock. I bet if
I did this to my 3670/Eagle (even with it turned off), it
would crash and never spin again.
Another tip about moving a machine: wrap packing tape around the card cages to
hold all the boards in place, and when you reach the destination, make sure all
the boards are seated properly and haven't jiggled loose. Only a trained professional
knows how to do this without breaking pins on the connectors, so be careful.
Any time you move a machine, reseat all the large boards
using my patented method:
1. Pull the board out by it's ejectors, then plug it back in
with the ejectors. **Make sure the board is seated in
it's track before trying to engage it's connectors**
2. Take a DC300 cart tape (in it's case) and place it's long
edge along the board's panel.
3. Smack the cart tape case solidly with the heel of your
palm. You should feel the board set at least another
1/16th of an inch.
NEVER trust the ejectors alone to set any large board in a
lispm. After reseating all the large boards by the above
method, make sure all the small paddle boards are seated by
pushing them in by hand.
