You need flash bracket, something like http://www.ckcpower.com/flash.htm

When you fire your A70's internal flash, the flash light will trigger the slave sensor which will then trigger your mounted flash. Flash metering on the mounted flash is totally dependent on the flash itself ( so it must have a thryistor (sp?) sensor ), or manually controlled. You'll also need to adjust the FEC on your A70 to avoid over exposure.
You can also try using a Sigma 500 DG Super or 550EX or 420EX and set them as wireless slave, triggered by your main flash. In this case, you won't need the slave sensor since this is built into the flash, but I'm not sure of the exposure accuracy. You'll probably need to adjust the flash ratio by using FEC on both body and flash instead.
