A wee bit off topic but hopefully the areas of interest will overlap enough
for some....

For many years (20+ ???) I have had an interest in the possibility of
building a motion simulator but it has been one of those things that never
quite happened.
I am not a great games player but would love a decent rally driving
simulator which allowed one to "suspend disbelief" in that environment.

I now have an opportunity to buy a "RocknRide" motion simulator "used only
on weekends for demonstration purposes by a little old lady who owned a
computer store" (not quite) for about 1/4 of the new US equivalent price.
For those who haven't met them this is a 2 axis (front/back and left/right)
chair with a swing in each axis of about +/- 26 degrees. Operates on
pneumatics with its own small compressor and has RS232 or joystick control
Extremely simple but workable and appears robust enough.
Offers possibility of interposing a device between eg PC game or whatever
and simulator to modify response in various ways.

MAY be the only one in the country.

Not too much general comment on the web that I have been able to find
although what I have found has been generally positive.

Has anyone met these?
How "good" are they?
Any thoughts on reliability or any other aspects ?
I'm being slowly enticed by the prospect but some independent comment would
be of interest.

Y'All welcome to play occasionally if I buy it but it's a long way to swim
for most of you :-)

For what it's worth - specs of apparent acceleration at 26 degrees tilt
angle are attached.

TIA
