NO NO NO NO NO!! DANGER WILL ROBINSON!!!

Before you do anything, please check one thing first!  I asked the same question
awhile back and got no responses.  I connected my 1300 to my 500 and poof!

Apparently, the -5V line on the RGBport of an a1000 is -12V on a 500.  I dunno
if it's also changed in a 2000.  It may be that the current-limiting resistors
will bring down all the voltages to a safe level, but I suspect that, 
depending on the particular machine, the 1300 would
either eventually self-destruct or not get enough current to run well in the
first place.

In any case, a better solution would be to make an adapter and externally-power
the A1300.
