@OP:
the AGA-2000 has a DB9 *VGA* output, which cannot be used on an EGA monitor. What you need is a DB9-to-DB15 converter cable or make your own, which is pretty simple if you have some dead IBM clone hardware laying around to grab the plugs from (a DB9 from a serial port, and a DB15 from a dead VGA card). Here are the pin-outs:
Although Microway is not our product, (Ours is HD-SUB 15 pins) but we'd like to help any users. ;-)
Wish you have got what you need.
If don't, please refer the following: DB9 for VGA pin outs. (differs from a EGA or CGA connectors)
Pin 1: Red Video
Pin 2: Green Video
Pin 3: Blue Video
Pin 4: H Sync
Pin 5: V Sync
Pin 6: Red Return
Pin 7: Green Return
Pin 8: Blue Return
Pin 9: Ground
The RGB returns are equal to the Ground.
