Khalid,
The first signs of power supply problems due to overloading usually come in
one of two ways, depending upon the supply.
1. Complete shutdown of the supply, sometimes requiring you to switch off/on,
sometimes resetting itself.
2. Erratic errors.
In the first case, the supply detects an overcurrent condition and "crowbars"
itself off, while in the second case the supply is not so well protected, and
as the current goes up, so does the amount of ripple. Also, as the current goes
up, the regulator may not be able to maintain the voltage.
If you have bene running for two weeks with the configuration you mentioned,
I wouldn't worry about it.
The Amiga's power supply is quite robust. A friend of mine, who is building
an add on peripheral was making mods to his design, and made a wiring error
that shorted +5 to ground. When he turned on the Amiga, it literally shrieked!
(I know, because I was talking to him on the phone at the time). It took him a
few seconds to realize that he should hit the power off, and when he found out
what happened, he corrected it, crossed his fingers, and powered up. No damage
was done. Obviously a well designed supply.
Regards, Larry.
