SA does have AG, right?
In any event, if you have AG, you can do this:
As you closer to a gravitational source, time slows. So, if you get closer to anti-gravitational source, time should speed, no?
Make as "high" a chunk of space-time as you can, then put a computer at the top. Depending on the AG design, you may or may not need your computer to handle serious amounts of gravitational stress.
